Electrical Problem?
 
I have a 91 s10 Blazer Tahoe and I have a electrical problem I think. When I'm driving down the road, my lights on my instrument panel flickers rapidly. I remember a few months ago that a friend of mine said that some connection to the battery or something wasn't right and that's all I heard from him. He's out of town and I can't seem to find anything wrong electrical wise. When I changed out my thermastat a months ago, I remember that the ground wire from the lights on the instrument panel connect to the screw on the thermastat. I've also noticed that the engine has also been running funny lately. Does anyone have a clue what my problem might be?

have you taken you instument panel or the dimer switch for it apart yet. it may just be loose on the switch. I also have seen when people put new radios in the panel flickers or doesn't work at all.

I taken everything part and nothing seems wrong or loose. I had the instrument panel repaired about 7 months ago so I know it's not that. I did however recently put in a new radio but don't see why it would be that.

alot of factory radios have dimmers in them to, after market usualy don't, the wire might be floating around or you may even be using the dimmer wire for the radio as a ground on mistake, many do because it is a ground wire but not intended for power source grounding. take the radio out and see if the wire is taped up and if it is then you are good on that. if you can't find it, then you or who ever hooked it op accidently used it. That is were I would go next! let me know if this doesn't help. I may have a few more ideas.

FYI If it is in the radio this can couse engine problems due to shorting the electricle system, I know from my dumb messups

Think I found the problem. It's not the radio becuase I taped up all the wires before I installed it. I was messing around with a few wires in the engine compartment and something reset my milage on the instrament cluster. I messed around with a few wires on firewall right above the blower moter for the ac, the battery, and on the alternator. Something reset it and I'm going to mess with each one in the morning to see which one it is. Maybe it's also causing some of my other problems.

see if any fuses are blown in fuse box and check all wire connections going to it. if you have a multimeter and know how to use it check battery for charge as the alternator might be shot. good luck
