What is the Heater Blower Motor Resistor all about?

The heater blower motor resistor is located underneath the dashboard in the heater/AC compartment. The resistor enables the heater blower motor to change the speed of the fan. Without this part you will not be able to change the speed of the airflow from the blower motor. It is also possible that the heater motor blower may not work at all. If the resistor has gone bad, it is likely that the fan will work only on the highest speed.

Keep in mind:

*If no air is coming out of your vents, you may have a problem with the heater blower motor as well as the resistor. * Mechanical resistance to the fan (such as when something gets stuck in the fan), can often cause damage to the heater blower motor resistor.

How it's done:

Inspect electrical circuits to verify faulty resistor.
Remove and replace the faulty resistor.

Our recommendation:

The air and heating system in your vehicle is a closed system, so it won’t be inspected during servicing and routine maintenance. If you notice any part of the air and heating system behaving bizarrely, however, you should always schedule an inspection. If your fan is stuck on high, you likely have a bad heater blower motor resistor, and should schedule to have it replaced.

What common symptoms indicate you may need to replace the Heater Blower Motor Resistor?

Blower motor only operates at 2 speeds instead of 4 speeds.
Blower motor is not functioning (no air from vents).

How important is this service?

To ensure proper operation of the blower motor, the resistor has to be working correctly or else you may end up with either no airflow from the fan or your fan will be stuck on one speed.

Mercedes-Benz 300SD L5-3.0L Turbo Diesel - Noise from engine or exhaust - Mountain View, California

Robert is good or even better than the other reviews. He does not only solve your problem but he ensures that your car is at its best before he leaves. He tries very hard to make your car perfect. When parts are not available he will try to make it. I regret very much not to hive him a tip when he left. It seems that Robert has a very busy schedule. Perhaps, his devotion to perfection takes extra time and make him a little bit late on schedule.
