Where is the blower motor resistor in a 98 Grand Prix?

Answer 1

I did this job on a 1999 Grand Prix, and I believe the location is the same for the 98 year model. First of all you will have to remove the blower motor itself. It is located on the passenger side floor board below the glove compartment, up against the firewall. It is an awkard job and I found that what worked best for me was to lay on my back with my head up against the center console. Once you have removed the 4 screws that mount the blower, disconnect the electrical connection and remove the blower. It is a tight fit around a wiring harness that is in the same area, but with some effort, it will come out. The blower motor resistor is located inside the duct work where the blower motor goes. There are 3 screws holding it in place, one of which is hard to see. A mechanics mirror comes in handy to locate the hidden screw. I would also advise that you replace the blower motor along with the resistor so that you don't have to go through the aggrevation later. I bought both parts through the local Auto Zone, which was much cheaper than the dealers cost. Both worked just fine. Good luck.
