Electrical???????

I am having a problem with a 2000 GP/GT, it started with the blower motor coming on all by it's self in the middle of the night, I just happened to be outside and heard it and pulled the HVAC high fuse.then about a week later the gauge lights started going off and on intermitently. I looked around for a short, but everything seems OK, also when I put the fuse mentioned eariler, back in the fan seemed to work fine. Any sugestions on what to look at next would be greatly appreciated.

Did you ever find the problem?... my 2000 GTP just started doing this.
thanks

I have a 1998 Grand Prix GT and recently the all the interior lights went out except for the radio. i have been trying to figure out where the short is coming from or if it is a faulty ground somewhere. someone suggested looking into the wiring for the moonroof as it caused severe problems with his electrical system. have you figured out your problem and/or could you give any advice on your findings?
