This is a sure sign of bearing or manifold wear. heater fan.

When choosing a spare part, it is important to understand the difference between the original and analogues. The original article is often overpriced, but the build quality is excellent. Cheap Chinese copies may be louder and have a shorter lifespan. Pay attention to the type of connector and the number of contacts - sometimes different versions of motors are installed on the same model.

• 🔍 Check the voltage at the motor connector with the ignition on and different fan speeds.
• 🛠️ Evaluate the play of the impeller - if it dangles, the motor cannot be saved, a complete replacement is needed.
• 💰 Compare prices: the original is expensive, but branded analogues (for example, Denso or Sanden) are often identical in quality.

⚠️ Attention! If the motor hums but does not spin, do not try to “swing” it by applying increased voltage. This may short out the windings and burn a fuse or climate control unit.

Place a rag or rug under your feet in front of the passenger seat to avoid scratching the floor or losing small parts. Nuts and screws often roll off into the most unexpected places.

Removing the glove box (glove compartment)

Basic access to stove motor carried out by removing the glove box. This is not just a box for documents, but a complex assembly with shock absorbers and clamps. Start by opening the glove compartment and removing all contents.

On the sides of the drawer you will see stoppers that limit the opening angle. They need to be squeezed out carefully. They are usually plastic pins that fit into slots. Use a flathead screwdriver to gently pry the clips up or to the side, depending on the design.

After disconnecting the limiters, the glove compartment will open as wide as possible. Now you need to unscrew the screws holding it suspended. There are usually three of them: one on top, two on the sides or bottom.

• 🔧 Unscrew the screw at the top of the drawer interior.
