98 Xj stock radio. If the key is turned on the radio works fine. Once I crank the reception goes out. Sometimes it works while the jeep is running. If it does, it normally goes out when I turn on the blinkers or windshield wiper. In the past I have been able to hear the blinkers through the speakers. Has anyone had these issues. Also if the reception hoes out. I can normally turn it over to a cd and listen for a minute then switch back over to fm and it will work.

 

Sounds like you have a bad ground somewhere

 

I'm thinking the same thing. But where would I check. Where would all those come together. Radio,blinkers,wipers?
