Been having a lot of trouble with my 2009 Chevy HHR. The dash gauges turn off intermittently and the dash lights will randomly turn on and off with it. I also have been having trouble with my aftermarket radio receiving power. If I take the radio fuse out and put it right back in, the radio will work fine for about 5 minutes. The fuse itself is fine, I even replaced it to be sure.
I began to think this may be an issue with the body control module, but I noticed something else today. When I take the radio fuse out and don’t put it back, I’m given a “Service Tire Monitor” warning, but then absolutely no dash gauge problems at all. I drove it for 3 hours today with the fuse out and had no problems. So, is this still an issue with the BCM? Or could it be as simple as needing to replace the aftermarket radio? Where should I go from here?
