Impala Blower Motor Resistor Removal

blower motor resistor need replaced

It's on the bottom left side of the engine at the fglywheel. It is round and about a foot long. Follow the large red power wire down to it.

The blower resistor is part of the blower module which is located on top of the blowercase under the hood. Just by the blower motor , hope you find it.. It will also have 2 plugs on it..

is it HOT or just not as cold. If its HOT, like heated air, there is a door problem, if its just not cool, the a/c refridgerent is low and will need a recharge, most likely the comp is leaking.

Automatic climate control uses a temperature sensor to detect cabin temp. I would look at that circuit for the problem, as it may be getting erratic readings from the sensor to the control unit, causes the blower to become confused to the air temperature in the car. You could probably find the entire climate control unit in a salvage yard to swap it out for a low price.

I have the same problem on a 1988 lesaber Climate control and was told to change the climate control as the was the problem. A have the climate control but have a problem to take of the cover that covers the control and the radio. If any one can tell me how to remove it I will put in the new control and see if that will stope the fann.Thanks

check the fuse box and under hood ,check one by one with the climate control on and radio lights on , and you will see when the radio its off or on.

The resistor is located on the blower housing on the firewall under the hood under the relay center boxes.
