So, about 2 days ago my HVAC cluster went from working perfectly to not having any fan speeds at all. I've had this issue before and I thought that it would kind of just fix itself like last time, but this time around seems to be a little different. 3 days in and no blower. I don't really even know what to check.
I read that there could be a bad ground somewhere that would stop the fan from working, and I think I have something to support that, behind the instrument cluster there is what looks to be a loose ground wire connected to the body but loose on the other side. It is Mopar branded and has that weird orange/yellow foam stuff around it that the temperature selector cable has.
I don't have a power station or anything to try to feed the blower 12 volts, and I don't think the relay is bad. I recently replaced the resistor (like 2 months ago) and the cables going into it are just fine, not melted. Matter of fact, all cables seem to be not melted.
Any help on diagnosing this would be awesome. I hope it's not the whole HVAC cluster, the slider-control style ones that I have are so much more expensive than the dial controls. Am I able to replace just the selector switch? It seems like it would come out easy.
