Heater blower resistors
Heater blower resistors
I am getting ready to work on my daughter's '92 RS, again. The heater blower has been making noise on the lower speeds. Last night she said it quit all together and the burned smell in the car was unbearable. I have a blower motor coming already, but the question is this; Is the smell coming from the motor or do we have low-blow resistors or relay burned up too? She is out of town with the RS, so I don't have it here to inspect yet. Also, where would I find those resistors/or relay? Thanks in advance!

You could apply +12 volts to the blower motor and see if it spins or smells burnt. If her motor doesn't work at all, on any speed, either the motor's burnt or there's a wire that's part of the climate controls that can get hot and burn. Something about using a plastic connector that heats up and causes more resistance and heats up more and causes more resistance and heats up more and ....

most likely it is the motor. i fot smelled real bad before it quit, it is usually the motor. when the resistors go bad, the motor will just quit on all speeds but high.
