Hello,
This my first try at posting a question. I have a1997 Z28 Camaro it has about 68,500 miles on it. My problem is the power windows and the radio. What happens is the power windows will go down then stop like no power to them. Or they will go up and stop the same way with me pushing the button like I am raising or lowering the windows. At the same time the radio goes off; I mean no power at all it does not even show the clock time. If I hit a bump sometimes everything will work for awhile. Some people told me it sounds like a ground problem. The dealer wants $138.00 an hour to look at it . Any advise would be appreciated.
Has anyone else had this problem ? Other than that , the car runs great ! This started about 6 months ago.
Thank you,
Johno58
