I have the electrical gremlin!!!Have read posts, been to 2 dealers and a gm mechanic friend of mine which had my car for 5 months with no success. I'm very fustrated .The Thread i read on the 13 grounds and dirty connectors, ETC. All gauges, windows, air, codes such as loss of power, etc. go off at random, turn car off and restart and every thing is fine for awhile. I noticed when I turned the stock radio on it would set things off instantly. Had dealer take radio out and they thought they had fixed it. No codes thrown at dealer then within an hour later it went crazy again. The dealers ran diagnostics on bcm and said the problem was before the bcm. I put a door control mod. in passenger door and it fixed power window. drivers power seat never worked since i bought it used. trunk lid popped open one night on its own in front of the mechanic whom had it for 5 months. said also ignition chime came on with no key in ignition. new battery was completely drained on two occasions overnight. car drives great regardless of these problems but cant use electrical components in car when this all happens. The radio was the only thing when removed seem to eliminate the trigger for awhile .Dealer says it will take many hours to find issue and laughed. I'm not laughing with him. Some body help, please. Did have most grounds and coplugs cleaned and seal from water issues. Note that waterdrains were clogged with leaf debris and water had gotten onto bcm and pcm but were opened and inspected for water entry. didn't seem to have entered either. CLEAN CARFAX ALSO.

 

did you do a carfax on the car before you purchased it? sounds like a flood vehicle having all those grimlins

 

Bought it off an individual, the water was slight on bcm and pcm, could see where the water traveled. came from windshield area where there are drains that can get clogged, then run behind firewall.

 

didnt do carfax though. can still do that though. a little late I know.

 

nice pic by the way

 

Checked carfax is clean. But noticed car had electrical checked at 2 local dealers 30k miles ago. Will check with them to see whts up. You actually led me in a direction that may have helped. We'll see. Thanks.

 

Be sure and check G105, ground under the block, drivers side. That one can be a cause of a million problems. Take it off, clean, dielectric grease it, new lock washer, etc. Contact Bill Curlee as well. He is on this forum and knows more than most everyone on electrical probs.


Good luck and don't pull out to much hair!

 

There is also a therad with the wires on the door causing all kinds of codes to pop up. I can't remember exactly which thread that was though.

 

Thank you. I will as my mechanic didn't clean all the grounds, just in the engine compartment on top. This may be difficult as its cold and i have no lift for ease of access. Will figure a way though. Bill curlee is the posts i was reading. Will go back to that. Thanks again

 

Wires in the doors looked good but none were tested.

 

Would be nice to know someone in cincinnati like bill curlee whom could check it out. This has gotten exspensive and still no resolve.

 

I suspect a grounding problem first then a crimped or frayed wire next. Only long diligent work inspecting it in total. Using a multimeter would help.

Good luck. If you were closer I would help as I'm retired and like to solve those pesky troubles.

 

I appriciate the help, bring all you got fellas. I have been quite alone in my new venture here. I bought this 2000 vette in july of 2010 and have driven it all of an hour if that since i bought it. Its my 1st vette to boot! What a good looking car , just want the gremlin to go home.lol

 

Didn't mean to forget the lady vette owners out there. bring it on ladies!! pics are welcome!lol just kidding. back to gremlins. haha
