Electrical problem
2004 Pontiac Grand Prix 6 cyl Automatic 120000 miles

I have a 2004 Pont GP. My blower will not shut off even when the engine is not running. It will only blow on #5. I have pulled every possible fuse in both electrical panels and nothing shuts it off. I took it to a mechanic and the only thing that he could do was to disconnect the blower all together. Now, I am without heat & window defroster which is a necessity. Please give me the magic CURE that's not going to cost an arm and a leg. Thanks in advance.

There is a bulletin that might relate to your problem, 05-01-39-001.

The cure was to install a capacitor at the blower motor control module connector. The bulletin describes how to install the capacitor.

There is a fuse in the power distribution center, under the hood, bat main 4, 30 amp fuse. I thought that would kill the blower?
