This part controls the speed of the blower motor on vehicles equipped with an automatic climate control system. Usually when these units fail, either the blower motor will run constantly, even with the key off, or the blower motor won't work at all.This part is the same as you would get if you walked into a GM dealer's parts department and purchased it. The only difference is that it's way cheaper.This part is usually very easy to replace.
