Re: 91 Olds 88 Blower motor/resistor Question
it is not attached to the blower motor- the resitor is in the HVAC case held in by two 7mm screws- the purple wire runs from it to the blower motor- trace the purple wire backwards to the resistor-- now what are your symptoms? no high speed blower? no low speeds on blower? or no blower at all? do not forget that tthe ground wire is as important as any other-- did you put 12 volts to the blower at the same time you provided it a good ground? Most blower fail by being intermittent- does yours come on when you tap on it? if so it has a dead spot and needs replaced.........
