The Blower Motor Resisotr Pack is defective. Replace it. diagnose the blower motor resistor circuit... read up on how... everyone should have a manual for their vehicle, and a professional shop manual should be available at the library in the reference section for FREE...make copies of the right pages and fix your vehicle like a PRO! :) good luck Dave :)
The blower resistor controls the speeds of the blower motor Hi-resistance lower motor speed Lo-resistance higher motor speed
Probably your blower motor speed resister is burned out.
If the one speed it works on is high speed, it is the blower motor speed resisitor that is bad.
The fuse. The blower motor speed resistor. The blower motor relay. The blower motor switch. Check for power at the blower motor connection.
Replace the blower motor speed resister.
Your blower motor resister, which is a circuit card located in the bottom side of the blower housing ( just over your front passenger's toes ) is most likely partially cooked - replace it.
usually mounted on or next to blower motor
Need to know what year. FYI, the relay for the blower motor only operates the high speed function. The lower speeds are operated by means of the blower motor speed resistor.
sounds more like blower motor resistor cost about $30.00 from dealer and 2 screws hold it in place
blower resistor is bad
The blower motor speed resistor is burned out. The resistor is usually found close to the blower motor. Auto parts stores carry that part and it is easy to replace.
The blower motor speed resister is burned out. This part is available from your local auto parts store.
