Caprice 2000

whenver I trun on the right left signal or flasher signal or AC the wipers will start by themselves, also my doors lock will sometime work and sometimes not

The first problem is in all likelyhood your multi-function switch. Have a good mechanic check it out. If it needs replacement don’t try to replace it yourself because the airbag system is involved. Your second problem is probably the main door lock switch on the drivers door. That’s the one that gets the most use.

I found something called a Body Control Module when I disconneted two plugs namely A and B everything was normal except that the car doesn’t start without these two plugs inn, what I’ll do I try to clean it with a CRC because the circuit board is fulll of dust maybe this will solve the probelem …any suggestioin
