I have a similar problem,whole panel a/c, radio goes in and out, I've replace the BCM (body control component) after market $80.00 and so far I have exchange it x2 and have not found one to work well with my specific vehicle. these cars have diferent parts for the same car year and model. no kiding. I took my 1990 buick riviera to GMC dealer paid $83.00 for labor. and they were able to tell me the BCM is the problem and checked all the wiring, althoug is pricy it is worth having a pro tell you what is wrong. Make sure you tell them to look for the problem ONLY and find another reliable shop to do the work for you, shop around on the phone for labor prices, and sure you are the one buying the parts your self, yes it is time consuming but you can save your self a whole lot of money.
Good luck.
