Fm radio problems

[Flatbed224]

I have a 2500 Ram it would Dale's driving down the road radio is working just fine hit a bump radio quit working there's no static no nothing just a slight hum when you turn the volume all the way up and it's only on the FM side not the a.m. side. a.m. side works just fine I've checked the antenna and it is plugged into the back of the radio I've checked all the antenna connections everything appears to be fine there. anybody got an idea?

Might want to take a look at the bulkhead connector up on the fender, thats a two piece I think and it may appear tight while not actually being tight. Otherwise, you may be stuck replacing the coax all the way from the antenna to the radio. As AM doesn't need much of an antenna at all, i'd definitely be looking at that cable and antenna for issues.
