Signs of a malfunctioning heater motor

Before starting the disassembly, make sure that the problem is in the fan of the heater. Symptoms often overlap with malfunctions heater resistor, fuse F37 (30A) or climate control unit (J255). Here are the key signs pointing to a motor:

• 🔊 Noise/grinding when working the stove - worn bearings or getting garbage on the blades.
• 🌀 No airflow at 1-2 speeds, but work at 3-4 is a typical symptom of wear of motor brushes.
• 🚫 Complete refusal fan in all modes (check the fuse and relay) J317!).
• 🔥 Burning smell from deflectors - a sign of burning the winding or jamming the shaft.

For accurate diagnosis, disconnect power connector motor (available from the passenger's leg) and apply to it +12V directly from the battery. If the fan doesn't turn, the problem is it. If it is spinning, but weak, check it out. resistor (located next to the motor).

Another common problem is squeak after replacement. It occurs if:

• Not lubricated bearings New motor (use silicone lubricant).
• Poorly fixed snail - Check all the clips and bolts.
• Got it dust Between the blades and the body - blow with compressed air.

⚠️ Attention: After the replacement of the motor on the machines with Climatronic an error may appear 01314 (no signal from the fan). To reset it, perform the procedure. basic settings through VCDS or OBDeleven (channel 08, adaptation 10).
