Default Heres a fun electrical prob for ya

So my battery was going dead for no apparent reason. That means sumthins drawing on it right? First thing, I check the fuse box. The 25a CB for the power seats is red hot and melted that black piece of black tape that covers it. So I pull it out. Well battery problem fixed, but what the heck is wrong with my seats? Is there a common problem anyone knows about or do I have to do the unthinkable and yank my seat out and start ohming out wires and all that fun stuff. Anyone else have this problem?

I haven't heard of a common problem. Check for stuck switches caused by accidental spills, etc.

If it actually got the relay that hot, I'd almost be willing to bet real money on a short somewhere. Unfortunately, that most likely means getting under the seat(*) and checking connections/wires

did you run over a wire with the power seat? Pinch a hot lead and you are grounding it to the body ground? I'd look for the easy and obvious. Check the routing of the wires under your seats first. Then yank the carpet up on the d/* (usually where all the power runs on GM'*) and see if something chaffed or rubbed the coating off.

You are looking for something easy but sometimes tough to find

did they work before you pulled the fuse out? (If it was dead shorted they wouldnt)

I would be willing to bet really bad connection at the fuse causing arcing or maybe a screwed up fuse/fuse holder causeing arcing.

If the seats still worked i would say arcing/intermittent shorting in the fusebox.

If the seats didnt worked.. then get out that multimeter

f you like the position that your seats are in then just pull the fuse and dont worry about it till you grow/shrink/sell the car

Go Brandon... that'* the painless, easy way out. Me on the other hand...I wouldn't care if the car blew up. Seat'* gotta work. And the first person that messes with my seat gets a serious smacking.

He might have a point. If the alternator gives off too much voltage then SOMETHING has to eat that. In my dads truck it was the headlight switch that caught fire one fine evening. The fusebox coulda been what ate it on his... maybe?

Worth a check so that it doesnt destry anything else.
