I just finished having my heater hose fittings replaced, when I got home from the garage; I noticed that my a/c fan kept going even when the car was off. I removed the key, restarted the car, messed with the a/c controls but nothing worked. Finally looked up online and saw someone post that the blower module could fail and cause the problem. Its called a Blower Motor Resistor, part number: 18306-07038930. Its found under the passenger side, removed by scrapping off the plastic screw holding it in. Its a rectangle shape with metal plates sticking out from one side. I removed the resistor and bought a new one cheap at partsgeek.com, after the 4 days for it to arrive I replaced it and had my a/c back to normal.

Initially, the fan would not turn off . The mechanic unplugged something so we could use the car for that day.

After he "fixed" whatever it was (he said he replaced the blower fan I think), it worked okay for a few days. Then the fan wold not work at all. He said it was a defective part & replaced it. I took it back 2 more times with issues. Finally sold car to my sister thinking it was fixed & she told me it wasn't working again!! She had it fixed. Mechanic told me he took cover off (not sure of what) & LOTS of water came out. He replaced whatever it was, put a different gasket on (he said it was a better one) and he says it is working now.

I ran my car through the car wash on a cold day, and the next day after starting it up the blower ran on high. The speed control was gone, and when I shut off the car and pulled the key, the blower continued to run on high until the battery died. Since then I've been pulling the 30 amp fuse on the panel under the hood on the passenger side. After doing an Internet search, I've found that this problem happens to many GM car owners. I pulled every fuse and relay on the fuse panels on both sides of the dashboard and under the hood ... no luck. I also pulled the glovebox off and checked for an obvious burnt relay or fuse under the dash and found none. I finally took it to a dealer to get soaked in the wallet for what appears to be an obvious design flaw of some kind. Just check out the Pontiacs on this site that have had this problem. Sheees!
