I have a 2006 Cobalt, about 82,500 miles on it. Been a good car - just done basic maintenance and changed batteries and tires periodically - no serious issues until last month when timing chain skipped and bent valves - had to have upper part of engine rebuilt. Before it was brought in to the shop, the radio worked completely fine. When I picked it up, the display was blank, so no clock, no showing what radio station you were on etc. The knobs would work so you could turn the radio on and off and switch the channel - but had to wait for station identifier to tell what station you had since the display was blank…none of the actual buttons worked, except the one to eject a CD.
Mechanic said the wiring in the radio is fried . . . somehow. This seems just a little coincidental to me. He told me they had to jump it because they left it sitting outside for several days (it was in the shop over 2 weeks). Could this “frying” have been done when they jumped it? Or is it REALLY just an EXTRAORDINARY COINCIDENCE. Of course he said he could find me a replacement radio and install it for me - I’m just not sure I want to be a repeat customer. Appreciate some feedback!
