The average replacement cost of a blower motor resistor is between $90 and $175. Expect to spend about $40 to $100 on the part and another $50 to $75 for labor if you can’t perform the replacement yourself. However, you should bear in mind that the most common reason for a bad blower motor resistor is due to a bad fan motor. That would increase the amount of troubleshooting you can do before you require an AC tech. Check the following things. Start the car, turn on the AC with the fan speed set to 4, and set the temp dial to the coolest setting. Look through the kidney grills and ensure that the AC fan it working. Connect an AC pressure gauge to low pressure 1. Yes, the mechanical fan is out, and in it's place is the Behr electrical fan, but the Aux fan has yet to be removed to troubleshoot the lack of normal fan operation. 2. Yes, I have installed the 5 speed Behr fan in the proper place between the radiator and the engine where the Mechanical fan used to reside. 3. The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all. The average cost for a BMW 525i Blower Motor Resistor Replacement is between $131 -$264. Learn More.
The most common causes that hinders normal operation of air conditioning system on your BMW 228i are dirty cabin air filter, refrigerant leak, dirty or clogged condenser, dirty or clogged evaporator, bad blower motor, defective compressor, faulty blend door actuator or any fault in the electrical system. 1. Dirty cabin air filter.
If low speed does not come on: With the aux fan low temp (green/black to black) switch jumped, check for voltage on both sides of fuse 3. If you have no voltage, the K1 relay is suspect. If there is any appreciable difference across the fuse, replace the fuse. Check for voltage at aux fan resistor on the black wire.
