My Roadmaster bogs down and sounds like it's trying to die when I use my wipers or when I turn the a/c on. Had this problem before and I had a local garage check it out. They said it was a bad ground. They fixed it. Everything worked fine for a week or two and then the same problem came back again. Any ideas?
Car bogs down when wipers or a/c is turned on on 1993 Buick Roadmaster
how is your alt diode? that would be my first check, after that take it to a diff shop and have them run an electric test to make sure your not drawing power excessively from the wipers/ac.
Problem fixed. The distributer went out and was replaced and now the problem is gone. Strange eh?
