It was 22 degrees this morning, 58 degrees yesterday. When I started the car this morning there was no sound/static from the AM/FM radio bands. However XM radio (not currently subscribed), the CD player and Aux input work fine. I can also hear the turn signal. The radio was working normally yesterday. Any thoughts? I will try later when it warms up a bit
Temp was ~21 degrees this morning. Same problem no AM/FM and Seek/Scan not working, so probably no signal being received by radio. The Equinox has a roof mount stubby antenna. There is a small gap between the antenna base and the roof. I will pull down the rear headliner and check for water intrusion and check and clean the antenna wiring connectors. Thank you for the suggestion.
