2002 GTP with Electrical Problem

[Marc48017]

Ok wife has a 2002 Grand Prix GTP. Well she calls me from on her way home and tells me that the car has a problem. When you turn the blower vent fan down to low the headlights and dash lights go out. If you turn it to more then low the lights are on and fine. Any ideas?

Ok..
Anyone know where I can get the wiring diagrams for the car?

alldatadiy.com could be an ignition switch problem or a bad ground.

I will have to look into the ground because we just had the Engine block to the idler coolant elbow replaced last week.

There are no grounds that would have to be removed to do that.

Yeah I know but I was thinking maybe the ground to the battery or something with the fuse box that is out there.

Is there somewhere online I can get the electrical drawings?

How hard are they to change and where do you get one?

And thanks everyone for the help.

I got a used one from moradpartscompany.com ... or you can go get one from a junkyard. It requires one or two "female" torx bits as well.

I would like to thank you guys for the info. I replaced the switch and it works fine now.
Thank you.
