Heater blower won't shut off
Hi, I've got a 2001 A4 Fronttrak and my heater blower won't shut off. A few days ago I noticed the heater blower was just blowing full blast, so I hit the off button to stop it but the blower won't shut off. I've tried changing temperatures but that doesn't really change the speed at all. As the car warms up and the cabin temp warms up, the fan doesn't really slow down. The only way to get the fan to stop blowing is to pull the fuse out.
I'm thinking there could be a relay that is stuck closed, but other than swapping relays out, not sure how to troubleshoot this.
