If the heater fan starts to whistle at age 6 of the first generation, you must perform the following steps:
- Eject the motor-heater's heater in the hull. He is behind the glove box and is fixed by three bolts.
- Next, we need to extract the motor from the body.
- Carefully disconnect the fan by unlocking the retaining screw at the back of the motor, and removing the handle.
- To make out the motor, you need a little hammering to push off the clamps.
- There are bearings inside. They're probably targets, but they're not much lubricant. We need to trim the compaction neatly, wash the bearings and put in a thick lubrication (for example, a lithole).
The assembly is in reverse order.
