How to replace the heater motor on a Nissan Almera Classic: detailed instructions with photos

Owners Nissan Almera Classic (especially models B10 2006–2012) sooner or later they encounter a problem: the stove blows weakly or stops working altogether at speeds 1–4. In 90% of cases it is to blame heater fan motor - its brushes wear out, the bearings jam, and the winding burns out. Replacing a part seems complicated due to the need to disassemble the dashboard, but with the right approach, the job can be completed independently in 2-3 hours.

In this article you will find step-by-step instructions with photos, tips for choosing spare parts (original vs analogue), as well as unique disassembly nuances that are not mentioned even in service manuals. We will figure out how to remove the motor without damaging the plastic clips, what tools are needed, and why the 4th speed may not work after replacement (and how to fix it).

Signs of a malfunctioning heater motor

The first symptoms of a breakdown are often ignored, attributed to a clogged cabin filter or problems with the thermostat. However, if you notice at least one of these signs, the motor requires diagnostics:

• 🔊 Extraneous sounds (creaking, squealing, knocking) when the stove operates at any speed. Most often the cause is worn out bearing or dirt that has gotten into the impeller.
• 🌀 Lack of air at 1-3 speeds, but work at 4th. This indicates wear brush assembly or oxidation of resistor contacts.
• 🔥 The stove operates jerkily or turns off spontaneously. The culprit is winding overheating due to an interturn short circuit.
• 🚫 Complete lack of reaction to change speeds. The fuse may have blown F30 (10A) or the motor winding is burnt out.

Before you mess with the motor, check:

1. Cabin filter - if it is clogged, air flow is reduced.
2. fuse F30 in the block under the steering wheel (to the left of the steering column).
3. Heater resistor (located next to the motor) - its contacts often oxidize.

⚠️ Attention! If the stove does not work only at 4th speed, the problem is fan relay (located in the fuse box under the hood). On Almera Classic This relay often gets stuck due to moisture.

Which stove motor to choose: original or analogue?

Original heater motor for Nissan Almera Classic B10 has an article number 27350-4M000 (for models with air conditioning) or 27350-4M001 (no air conditioning). The cost of a new original is from 8,000 to 12,000 rubles. However, there are proven analogues that will cost less:

Brand	Article	Price, ₽	Features
Nissan (original)	27350-4M000	8 000–12 000	12 month warranty, fully compatible
Valeo	696133	4 500–6 000	High quality bearings, quiet operation
Febi	27350	3 800–5 000	Budget option, possible noise when worn
Blue Print	ADN102001	5 000–6 500	Good price/quality ratio

When choosing an analogue, pay attention to:

• 🔄 Direction of rotation - must match the original (on Almera Classic - counterclockwise, when viewed from the impeller).
• 🔌 Power connector — some analogues come with a universal connector, which will have to be soldered.
• 🎵 Noise level — cheap motors often “whistle” at high speeds.

⚠️ Attention! If you buy a used motor, check the shaft play - it should not exceed 1 mm. Also inspect the brushes: their length should be at least 5 mm.

Tools and preparation for replacement

To replace the heater motor with Nissan Almera Classic You don’t need specialized tools, but you can’t do without some devices. Here's the full list:

• 🔧 Set of sockets and ratchet wrench (sizes: 10 mm, 12 mm).
• 🔨 Flat and Phillips screwdrivers (for plastic clips).
• 🔪 Knife or plastic clip remover.
• 🔌 Multimeter (to check the voltage on the connector).
• 🧲 Magnet on the telescopic handle (so as not to lose the bolts in the cabin).
• 🧴 WD-40 or equivalent (for treating rusted bolts).

Also prepare:

• 📦 A box or bag for small parts (clips, bolts, screws).
• 📸 Phone for photographing disassembly stages (useful during assembly).
• 🧤 Gloves - the plastic in the interior is sharp, easy to get hurt.

Before starting work:

1. Disable negative battery terminal (to avoid short circuit).
2. Set the steering wheel to its highest position (for easy access to the dashboard).
3. Remove glove compartment - this will simplify access to the motor.

Step-by-step instructions for replacing the heater motor

The most difficult stage is dismantling the old motor. On Nissan Almera Classic it is located behind the glove compartment, but to get to it you will have to partially disassemble the dashboard. Follow the instructions:

Step 1: Removing the glove compartment and trim

1. Open the glove compartment and remove all items from it.

2. Click on fasteners on the sides glove compartment (they are located inside, below the hinges) and pull it towards you. It should come out of the grooves.

3. Unscrew two screws in the lower part of the dashboard trim (under the glove compartment) - they are hidden under plugs.

4. Gently pry with a screwdriver plastic cover under the steering wheel (passenger side) and remove it by snapping the clips.

Step 2: Removing the motor

1. Disconnect power connector from the motor (it is black, with 3–4 contacts).

2. Unscrew three bolts attaching the motor to the stove body (head size - 10 mm). One of the bolts may be hidden under a rubber plug.

3. Carefully pull out the motor along with impeller. If it does not come off, twist it counterclockwise - sometimes it sticks to the shaft.

What to do if the bolts do not come off?

If the bolts are rusty, treat them with WD-40 and wait 10-15 minutes. If they still don’t work after that, use an impact screwdriver or drill them out (you’ll have to cut a new thread).

Step 3: Installing a New Motor

1. Check shaft play on a new motor - it should not exceed 1 mm.

2. Place the motor in place, secure it with bolts (do not overtighten, so as not to strip the threads!).

3. Connect the power connector. Attention: On some analogues the wires may be reversed - check the polarity with a multimeter!

4. Before assembly, turn on the stove at maximum speed and make sure that the motor runs without vibration.

Step 4: Assembly

Reassemble everything in reverse order. Pay special attention to:

• 🔄 Plastic clips - they break easily. If broken, replace with new ones (clip part number: 73201-4M000).
• 🔌 Connecting connectors - on Almera Classic The connectors of the temperature sensor and the motor are often confused.
• 🔧 Bolt tightening — overtightened bolts can deform the stove body.

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes that lead to repeated disassembly or breakage of new parts. Here are the most common:

1. Incorrect impeller installation. If you put it on the wrong way, the air flow will be weak and the motor will overheat. Correct position: the blades must be directed up (in the direction of rotation).
2. Ignoring the heater resistor. If the motor does not work at speeds 1–3, but works fine at speed 4, the problem is resistor (item: 27355-4M000). It needs to be cleaned or replaced.
3. Damage to plastic clips. On Almera Classic Dashboard clips are fragile. To avoid breaking them, heat the plastic with a hairdryer or use a puller.
4. Failure to check fuse. If the stove does not work after replacement, first check F30 (10A) - it often burns out during a short circuit.

Another typical problem is noise after replacement. If the new motor hums or whistles loudly, the reasons may be:

• 🌀 The impeller touches the housing — check the gaps.
• 🔧 Insufficient bearing lubrication - add a few drops litola.
• 🔌 Incorrect connection - Swap the wires on the connector.

How much does a service replacement cost?

If you don’t want to bother yourself, you can contact the service. Cost of replacing a heater motor Nissan Almera Classic varies depending on the region and service station level:

Service type	Cost of work, ₽	Lead time	Warranty
Official dealer Nissan	5 000–7 000	3–4 hours	12 months
Multi-brand service	3 000–4 500	2–3 hours	6 months
Garage craftsmen	1 500–2 500	1–2 hours	No warranty

Is it worth overpaying for official service? Only if you have warranty car or you are afraid of damaging the plastic of the dashboard. In other cases, it is enough to contact a proven multi-brand service.

You'll save money by replacing it yourself 3,000–6,000 rubles, but be prepared for the following difficulties:

• 🕒 Time — the first replacement takes 3–4 hours.
• 🔧 Tool — you can’t do without a 10 mm socket and a clip remover.
• 🔄 Nuances - for example, on some Almera Classic you will have to remove the steering column.

Prevention: how to extend the life of the stove motor?

The average service life of the heater motor is Nissan Almera Classic — 100,000–150,000 km. But with proper operation it can be increased by 1.5–2 times. Follow these tips:

• 🌬️ Change the cabin filter regularly (every 15,000 km). A clogged filter increases the load on the motor.
• 💧 Avoid moisture — if there are puddles on the carpet under the passenger’s feet, dry the interior. Moisture leads to corrosion of the motor shaft.
• 🌀 Do not turn the stove on high right away. In winter, let the motor warm up for 1–2 minutes at speed 1–2.
• 🔧 Lubricate bearings every 50,000 km. Use lithol or silicone grease.
• 🔌 Check the resistor contacts once a year. Oxidation leads to overheating of the motor.

If you notice that the stove has begun to make noise or blow weaker, do not delay diagnosis. In the early stages it is often sufficient clean the brushes or lubricate the bearingsto avoid complete replacement.

FAQ: Frequently asked questions about replacing the heater motor

Is it possible to repair an old motor instead of replacing it?

Yes, if the problem is brush assembly or bearings. To do this:

1. Disassemble the motor (carefully so as not to damage the winding).
2. Replace the brushes (suitable for any DC motor with similar dimensions).
3. Lubricate the bearings lithol or replace them (bearing number: 608ZZ).
4. Check the winding for open circuit with a multimeter.

However, if the winding burns out or the commutator crumbles, repair is impractical - it’s cheaper to buy a new motor.

Why does the stove only work at 4th speed after replacing the motor?

This problem is related to stove resistor (item: 27355-4M000), which is responsible for speeds 1–3. To troubleshoot:

1. Remove the resistor (located next to the motor, secured with two self-tapping screws).
2. Clean contacts from oxidation (use sandpaper or WD-Contact Cleaner).
3. If the resistor burns out, replace it (cost: 800–1,500 ₽).

Also check fuse F30 (10A) - it can burn out if there is a short circuit.

How to remove the heater motor without removing the dashboard?

On Nissan Almera Classic This is possible, but extremely inconvenient. Alternative way:

1. Remove glove compartment And trim under the steering wheel (passenger side).
2. Unscrew the motor, but do not pull it out completely - turn it 90 degrees.
3. Disconnect the connector and pull the motor out through the glove compartment opening, carefully bending the wires.

Disadvantages of the method: high risk of damaging wires or plastic, as well as the difficulty of installing a new motor.
