My a/c recently started only working on one speed and is super touchy. It only works on the third setting. I don't think it's the fuse because I would assume it wouldn't work at all of that were the case. I've had to replace the blower motor resistor on previous vehicles where I've run in this same problem. Only thing with this is I don't know where that is on the car. I've also seen people replace the whole climate control set up but would like to stay away from that if that's not the issue. Any advice would be appreciated.
