I've narrowed it down to the few components between the antenna circuit and the tuner. My CD and Tape work. But AM and FM do not. I swapped out the radio with a good one and it worked fine. So it's in the radio. When I hit scan it can't find any thing. This began a few weeks ago but it would come back. Now its not. From other posts this is not an uncommon problem. I have not been able to find a fix like the dim LED or climate control fixes that i've used with great success. Has anyone see a fix posted?
