I have the stock AM-FM dolby cassette radio in my 95 xj. The AM side works good the FM does not. (most of the time) Seldomly it will pick up a signal and work and it sounds great. It was like this when I got the jeep. I pulled the unit out, cleaned it and made sure the antenna had a good connection, still the same. I'm wondering if the FM side has its own separate receiver or booster as I think the problem isn't the radio itself. I'm not into crazy loud boomin systems, I just want something to listen to and I'm a fan of stock OE stuff. If worse comes to worse, I'll just have to put in a new unit. Help anyone?

 

behind the passenger side foot kick panel there is a connector for the antenna after it comes through the inside of the fender. Mine split open and the plug fell out killing all FM reception. I stuck it back together and used a hose clamp to hold the split socket around the plug. Works great now.

 

Yeah I checked that and it was OK, I didn't think that was the problem because AM works all the time and FM works when it wants to (seldomly)

 

check the antenae wire it may be bare and rubbing on metal causing bad reception
