electrical problems I have a 2000 Camaro Z28. The radio some on and off whenever it wants to. My windows also don't work (I think its just cause i don't know heavy window) anyway. I took it to the dealership and they said i had "major electrical problems" that would also be shorting out my window motors. were they right or do you think its just a bad radio.

Your dealer is either trying to get rid of you or wants to make as much on service as possible before going bankrupt. They obviously didn't really look at your car or else they're just incompetent.
The problem has nothing to do with your radio. Your Body Control Module (BCM) is going bad. The worst case scenario is that you have to buy a new BCM for about $200 (you can install it yourself in just a few minutes). But, if you have a little electrical experience (or have a friend that does) you can probably fix the BCM for nothing. Check out this thread for more information about the fix.
BTW, this problem will not damage your window motors in any way (which is a good thing considering how bad the motors are to start with).

No, a used BCM can't be reprogrammed to match the resistor pellet on your ignition key. So you'd have a 1 in 15 chance of getting a used one that would let you start your car. There are ways to work around that...you can bypass the VATS system or you can get the dealer to scan the used BCM to determine the programmed pellet value and then cut a key just like you have now except with the different pellet in it.

I have been to other mechanic places and everyone seems to think I'm talking about a throttle body. A dealership would know exactly what I'm talking about?

If you get a used BCM, you would probably have to get a new ignition key that has the same cuts as your current key but with a resistor pellet that matches the used BCM (there are 14 different resistor values so you have a 1 in 14 chance that your existing key would match). There are two problems with this option - even if your dealer knows how to scan the BCM for the correct code they will probably charge a lot of money to do so, and the used BCM may still have the same bad solder joint problem. You would be far better off to fix your current BCM using the method described in the link posted earlier. Even if you don't feel comfortable doing the soldering, you could remove the BCM and have a friend or somebody else do the soldering for you.

I was just about to post this exact same thing, glad i did some reading before doing so, I'm actually a tech at a gm dealer and this through me for a loop since they don't share a ground, splice or anything else except the bcm and didn't really want to buy a new one of those cuz ya fml they are expensive. Thanks for the input!!!!
