Not a very good mechanic but a worse electrician.

Got a 2000 with no windshield wipers, no rear taillights, and now starting to overheat but can't tell when.

Car repainted recently so has been apart some but was always running.

The windshield wipers have a good fuse. Far as I've gotten. I need a wiring diagram. I bought one of those DVD manuals but I can't get the dang thing to work on Vista.

Haven't done much more with the taillights. I know where to crawl under to check but thought I'd try to do it post diagram.

The reason to post here about the overheating is I don't think the fan is coming on properly for one. But it is coming on some. It won't run for very long after cutting the car off even though the engine is hot. I don't think that is right.

Also the car has a driver side only hvac climate control system. At times the outside temp reads -32*F, others normal, and others goes up and down. The AC on when working definitely causes the car to run hot sometimes but not consistently. At times the AC and the engine is running fine. I don't see a repeated pattern except that it does seem to run hot more often when the AC is running. (The water pump is working and I've got plenty of fluid in the radiator).

I need a diagram to figure out where the outside sensor is to keep the AC on and I wonder how it relates to the engine fans. The high engine temps should override the climate control and the fans. I don't even know if they are remotely related.

And if someone knows all the answers I'm not adverse to being spoon fed the answers to correct this stuff.

Thanks all. Looks like a great forum.

The electrical system on newer Corvettes is very complicated, more so than an ordinary vehicle. You have described yourself as not an electrician. In that light I might suggest that you take the car to a qualified mechanic. Re: the fan, it is controlled by the cars computer and uses various inputs from different sources to determine when it comes on and at what speed it runs....very complicated.

P.S. I'm not trying to be a smart #ss, but when Corvettes start having electrical problems they can be a real bear to run down. Since it has recently been painted and somewhat apart you need to first look for proper grounding. Make sure all ground connections are in place and in good condition.

Good advice and you're absolutely right about being a bear at times. If I had an electrical diagram I could probably do a little esp with the ground problems which I bet is part of at least one problem. I'm not going to take it to my corvette mechanic first this time. I'm trying to find someone who does this kind of thing around this area. I'm also new to the area which is probably my worse problem. Knowing who to let work on it is the problem right now.

Thanks for the reply and no you didn't come off as a smart aleck. Just friendly.

Just a word of advice, be very selective on who you let work on the car, especially a Vette. Go to car shows and talk to people and ask who they use for repairs. Most rodders know someone who works at home specifically on rods.

Check the grounds that go to the BCM first.. on a steel car that can make them go haywire, let alone, having a composite body which doesn't pass a current

Hadn't thought of that. Super idea. Probably too easy to be the problem but something I can do.
