Message The TT has 85k miles on it. No idea of when this started as I've only had it for 20 miles.

Has hot air blowing out of vents when heat/AC is off and when trying to turn on heat/AC the blower won't turn on.

For the blower I'm going to check fuses/relays and I'm 80% sure it's just a fuse but for the heat through vents.. This is my third Z and every one of them has had this issue. All are between 60-85K miles.

Is this a normal thing for Zs? Setting the temperature to 60 takes away most of the heat from the air in the other 2 Zs, but on this TT it doesn't do anything.

Am I looking at the gruesome fix of replacing all the climate control motors?
