Climate control fuse blows
 

Hey all, been having a problem with my 92 LS-l lately that the 30amp fuse for the climate control (and whatever else may be on it) keeps blowing.
When I got the car the heat/etc did not work. I replaced the fuse and it worked for several days with no problem, then blew again. After that, I replaced it again and looked around for any bad grounds and couldn't find anything obvious. It worked again for a few days, then I remember hitting a hard bump and the heat went off and the fuse blew again. Since then, it blows as soon as I turn the ignition with a new fuse in..
Anyone have any idea on where to start troubleshooting where the problem may be? Thanks!

Hi, welcome to the site. It's not going to be a bad ground causing the fuses to blow. (if that helps)

I have a short somewhere in my car that I'm going to try to find this weekend. I'll let you know what I find.

However something supplying power grounding is bad. check all the power wires back there and knowing full well I need to do a similar task of finding out why my radio keeps turning off(but only the top half)

How long does your radio turn off for? That's the short I need to figure out. I also get flickering dash lights but I know it's not the alternator this time.

disconnect the radiator fans - probably wrong, but I think that's the only 30amp fuse relating to climate control.

maybe someone better at schematics can help.

I had a short in my cigarette lighter that caused my climate control to blow it's fuse. Do you frequently use your lighter?

The lights on my (factory) cd player occassionally dim out also, yet it still keeps playing, dunno if that's related at all....
As far as my lighter, I don't think I've ever used it.
I took almost the entire dash apart the other day and checked the connections behind everything and all seemed well there also.
I need to get a service manual. Anyone know a good source?

Depending on which fuse keeps blowing, it could be the wiring for the vanity light on one or both of you sun visors. I would take a look at them.

the dreaded vanity light short - wierd how many things those lights seem to affect.

Well, my drivers side visor doesn't even exist (anyone have one they're selling?) and I have the wires taped off... I'll have to check on the passenger side today if this rain would stop... Damn lack of garage. Thanks for the tip.
