In winter, every owner Nissan Qashqai faces the problem of icing on the side mirrors - even after a short stay, a crust of ice forms on them, impairing visibility. The heated mirror system built into cars from the factory is designed to solve this problem, but often owners do not know how to use it correctly or what to do if it fails. In this article, we will analyze the structure of the system, signs of malfunctions and step-by-step instructions for diagnosis and repair.

Feature heated mirrors on Qashqai (like first generation J10, and the second J11) consists of integration with the rear window heating system - they are activated simultaneously. This simplifies control, but complicates troubleshooting: if the mirror does not heat, the problem may lie in the heating element itself, or in the power circuit or control unit. We will analyze in detail all the components of the system so that you can identify and fix the breakdown yourself.

How does heated mirrors work on a Nissan Qashqai?

Heated side mirror system Qashqai is activated automatically when the rear window heating is turned on. The heating elements are thin resistive films glued between the glass and the plastic base of the mirror. The heating power is about 5–7 W per mirror, which is enough to melt ice in 2-5 minutes depending on the temperature.

The electrical connection diagram is simple:

  • 🔌 Food is served through fuse F37 (10A) in the interior mounting block (on J10) or F40 (10A) (on J11).
  • 🔄 Management is carried out through rear window defroster relay (located in the same block).
  • 🔌 Mirror heating elements are connected in parallel to the rear window defroster circuit.
  • ⚡ Voltage is supplied to the mirrors only when the ignition is on.

On models with automatic climate control (For example, Qashqai 2.0 Tekna) heating can be activated without the driver’s participation - when the temperature drops below +3°C, the system turns it on for 10–15 minutes to prevent icing. However, on most trim levels the control is manual: the rear window heating button (with the symbolic designation 🔥) is located on the center console.

📊 How often do you use heated mirrors in winter?
  • Every day
  • Only after washing
  • As needed
  • I never use it

Signs of malfunctioning heated mirrors

The main symptom of a breakdown is lack of heating of one or both mirrors when the rear window heating is operating. However, there are other indirect signs that will help more accurately diagnose the problem:

  • ❄️ The ice on the mirror is melting only at the edges - this indicates a partial break of the heating film.
  • 🔥 The heating works, but the mirror gets hot unevenly (one side is hot, the other is cold) - the film may peel off.
  • 💡 When the heating is turned on fuse trips - short circuit in the circuit.
  • 🔌 Only one mirror heats up - the problem is in the connector or power cord on the side of the non-working mirror.

On Nissan Qashqai J11 (2014–2021) a specific malfunction occurs: the heated mirrors stop working after replacing the battery or resetting the BC settings. This is due to body control module (BCM) malfunction, which requires flashing or resetting errors through a diagnostic scanner. In such cases, an error may appear on the dashboard B2555 (malfunction of the heated mirror circuit).

💡

If the heating of the mirrors stops working after washing under high pressure, check the tightness of the connectors on the mirrors - water could get into the contacts and cause corrosion.

Heating system diagnostics: step-by-step instructions

Before disassembling the mirrors, check the power and control circuits. You will need multimeter (or warning lamp) and a screwdriver for removing the door trim.

Turn on the ignition and activate the heated rear window (button 🔥)|Check the voltage at fuse F37/F40 (should be 12V)|Measure the voltage at the mirror power connector (pins 1 and 2)|Test the heating element for an open (resistance ~1–3 Ohms)|Inspect the connectors for oxidation or moisture-->

Detailed instructions:

  1. Checking the fuse:

    Open the mounting block (located under the steering wheel on the left). On Qashqai J10 this is a fuse F37 (10A), on J11 — F40 (10A). Remove it and check its integrity. If a fuse is blown, do not replace it immediately - first find the cause of the short circuit.

  2. Relay test:

    Heated rear window relay (on J10 — K37, on J11 — K40) should click when you press the button. If there is no click, replace the relay or check its control contacts (pin 85 - ground, pin 86 - +12V from the button).

  3. Checking voltage on mirrors:

    Remove the plastic door trim (snap off the clips) and find the mirror power connector (usually black or gray). When the heating is on, there should be voltage between contacts 1 (+12V) and 2 (ground). If it is not there, the problem is in the wires from the mounting block to the door.

    ⚠️ Attention: On Qashqai J11 the power wires for the heated mirrors pass through flexible transition between door and counter. They often fray - inspect the insulation in this place!
  4. Checking the heating element:

    Disconnect the mirror connector and measure the resistance between pins 1 and 2. A working element should show 1–3 Ohm. If the resistance is infinite, there is a break; if it is 0, there is a short circuit. On Qashqai J10 There are mirrors with two separate elements (2–3 Ohms each).

If the heating element is faulty, it can be replaced separately (see next section). If the problem is in the wires, restore the circuit and insulate the damaged areas.

Replacing the mirror heating element

If the diagnostics showed a break or short circuit in the heating film, it must be replaced. On Nissan Qashqai this can be done without removing the entire mirror - just remove the glass.

Required tools and materials:

  • 🔧 Plastic puller or flat screwdriver
  • 🔥 Construction hair dryer (to soften the glue)
  • 🧴 Glass glue (for example, 3M 08609 or similar)
  • 🔌 New heating element (article for Qashqai J10: 26500-JM00A, for J11: 26500-4M00A)

Step by step instructions:

  1. Remove the plastic mirror cover by prying it with a screwdriver from the inside (door side). Be careful - the clips are fragile!

  2. Disconnect the power connector and remove the mirror from the bracket by unscrewing 3 bolts (usually a Phillips screwdriver).

  3. Place the mirror with the glass facing up and heat it with a hairdryer around the perimeter (temperature ~60–80°C) for 2–3 minutes. This will soften the glue.

  4. Carefully pry the glass with a plastic puller, starting from the corner. Try not to damage the old heating film - it will be useful as a template for the new one.

  5. Remove any remaining adhesive from the plastic base and degrease the surface with alcohol.

  6. Glue the new heating element, aligning it with the contacts on the base. Apply a thin layer of glue around the perimeter and press the glass.

  7. Leave the mirror under pressure (such as a stack of books) for 12–24 hours to allow the glue to dry completely.

On Qashqai J11 Since 2017, mirrors with integrated turn signals have been installed. When replacing the heating element, be sure to disconnect the battery to avoid a short circuit in the LED circuit!

How to check performance after replacement?

Turn on the heated rear window and after 1-2 minutes touch the mirror with your hand - it should be warm. If only part of the surface is heated, check the quality of the film adhesion (there may be air bubbles).

Common repair mistakes and how to avoid them

Many owners Qashqai encounter repeated breakdowns after self-repair. Let's look at the most common mistakes:

Error Consequences How to avoid
Using the wrong glue The glass will fall off in 1–2 weeks Use only specialized adhesive for auto glass (for example, 3M 08609 or Permatex 81878)
Overheating of the mirror with a hairdryer Deformation of the plastic base or damage to the turn signal Keep the hairdryer at a distance of 10–15 cm and do not heat one point for more than 10 seconds
Wrong polarity when connecting Short circuit and fuse blown Before assembly, check with a multimeter where “+” and where “–” are on the connector
Ignoring contact oxidation Poor contact and repeated open circuit Clean the contacts with sandpaper (600–800 grit) and sand LIQUI MOLY Kontakt-Spray

Another common problem is moisture getting into the mirror connector after washing. To avoid this, after repair, treat the connector with silicone grease (for example, WD-40 Specialist Silicone). On Qashqai J11 Since 2018, the installer began to use sealed connectors, but on earlier models this is a weak point.

💡

If after replacing the heating element the mirror stops heating after 1-2 months, most likely the problem is poor connector contact. Check the reliability of fixation and the absence of oxidation.

Alternative ways to combat mirror icing

If repairing the heating element is impossible (for example, there are no spare parts), temporary solutions can be used:

  • 🧴 Anti-icing sprays (For example, Liqui Moly Anti-Ice or Sonax Xtreme). Applied to a dry mirror in the evening, it prevents ice formation for 12–24 hours.
  • 🧊 Heated scraper (works from the cigarette lighter). Helps quickly remove ice, but does not solve the problem completely.
  • 🔋 External heater on clothespin (For example, Philips HF3420). Attaches to the mirror and connects to the cigarette lighter. Power ~150 W, heats up in 3–5 minutes.
  • 🧤 Mirror covers made of neoprene. Prevents icing, but requires removal before travel.

On Qashqai J11 with the system NissanConnect you can activate the heated mirrors remotely via a mobile application (if the car is equipped with a module NissanConnect Services). To do this:

  1. Install the application NissanConnect to a smartphone.
  2. Log in and link the car by VIN.
  3. In the "Climate" section, select the "Heated mirrors" option (available only when the ignition is connected).

This method is convenient if you want to warm up the mirrors in advance, but remember: prolonged use of the heating with the engine off will drain the battery.

Frequently Asked Questions

Is it possible to install heated mirrors on a Qashqai if it did not come with it from the factory?

Yes, but you will need:

  1. Buy mirrors with heating elements (suitable for mounting).
  2. Lay the wires from the mounting block to the doors (use corrugation for protection).
  3. Connect to the rear window heating circuit (in parallel).
  4. If necessary, modify the control button (some equipment does not have it).

The cost of such an upgrade is from 8,000 to 15,000 rubles (including spare parts and labor).

Why does the heated mirrors work, but the ice melts only after 10–15 minutes?

Possible reasons:

  • Low voltage in the on-board network (check the battery and generator).
  • Worn heating element (resistance is higher than normal).
  • A thick layer of ice or snow (heating is designed for a thin crust).
  • On Qashqai J11 As of 2019, the BCM firmware may limit heating power to save energy.

Solution: check the voltage on the battery with the engine running (should be 13.8–14.4V). If below, recharge the battery or check the generator.

Which fuse controls the heated mirrors on the 2010 Qashqai J10?

On Nissan Qashqai J10 (2007–2013) the fuse is responsible for heating the mirrors and rear window F37 (10A) in the interior mounting block. Relay - K37. The connection diagram is the same for all configurations (including Visia, Acenta And Tekna).

Is it possible to repair the heating film if it is torn?

Theoretically, you can try to restore the conductive layer using graphite glue (For example, Done Deal DD6700), but this is a temporary solution. The film consists of microscopic resistive tracks, and even a small damage leads to a break in the circuit. It is safer to replace the element completely.

Exception - detachment of contacts from the film. In this case, you can carefully solder them back using low-temperature solder and aluminum flux.

Why did the heated mirrors stop working after replacing the battery?

On Qashqai J11 (especially 2014–2017) body control unit (BCM) can reset when power is turned off. As a result, the heated mirrors stop turning on, although the fuse and relay are working.

Solutions:

  1. Reset errors via diagnostic scanner (eg Launch X431).
  2. Disconnect the battery for 10 minutes, then plug it back in - sometimes "resetting" the BCM helps.
  3. Contact an authorized dealer to reflash the unit (if resetting does not help).

If the problem persists, check the circuit between the BCM and the heater relay (pin 85 on the relay).
