My radio and blinkers will stop working at times. I jiggle the keys and all works fine. I have been putting of changing the ignition switch but haven't. Tonight while driving it happened again but with an added buzz under the glove box. This time jiggling the keys were a no go. I turned the heat off and no buzz. Turned the heat on and buzz is back. I pulled over and cut off the Jeep then cranked it back up. The buzz is gone but no radio or blinkers. Hazzard do work and fuses under glove look good. Changing the switch tomorrow but not the actuator. Any ideas or anything else I should consider?
