View Full Version : heater fan doesn't work

I have a 1998 Olds Intrigue. The speeds on the heater fan are going out starting with the lowest two speeds first, then the third and fourth fan speeds. I have been told that it is the relay switches but I cannot find them in my car. Does anyone know where they are?

HI debradk,

We don't make a manual for your vehicle, but if what you're saying is that the blower works only on HI, that's typical of a bad blower motor resistor. The resistor is located right next to the blower motor.

Obviously, we can't diagnose problems from a remote location, but like I said, that's a typical symptom of a bad resistor. That's if you have a manual HVAC system, not an automatic climate control system. Diagnosing an automatic system is considerably more involved.
