OK need some help here with a schematic or maybe someone knows this already. Daughter has a 96 convertible base with 3.8. Sometimes the electrical system shuts down some items. I know there is either a short somewhere or a relay cycling. So far the systems that don't work when this happens is the stereo, power windows and the power top. Eventually a few minutes later they start to work again. I looked in the Chilton's manual but according to those schematics there isn't any wiring in common with these 3 circuits. Anyone have better schematics or an idea of what's causing this? thanks a lot for any help.

 

sounds like it could be the body control module, have a look here

How To Fix Intermittent Windows, Radio and Locks

 

The RAP (Retained Accessory Power) supply is in common with all three. Like craby says, most likely the BCM since that controls that supply. A very common problem.

 

Thanks guys, the BCM was exactly the problem, I think. Took it out and in fact did find a cracked solder joint. Checked them all with an eye loupe and only found the one where it was guessed to be on the back of a relay so hopefully that's it. Now on to engine problems. Thanks again, I never would have found that otherwise.
