Ac only blows hot

Uxi · 09-20-2015, 08:44 PM

Ac went out today. 103, of course. Took a short trip earlier and was fine. Couple hours later now only blows hot. Wtf. No dummy lights. Turned off and on a couple times. No change.

Guess back to stealer tomorrow?

Possible blend door actuator problem. But then again..who knows. My car was throwing a code and idling high because it needed a battery. Never heard of that before. If you have a warranty I would definitely bring it in.

Check and make sure the compressor is running. If not, look for blown fuse. Or it could be interlocked on low pressure (see nismo13807's comment above).

If compressor is working, I'd look into GunWorxx's door actuator. Not sure how the doors work on the Z but there is a LOT of info in the FSM (see link in my sig).

I had the same problem with my 2006 350Z before and had to take it to at least 3 Nissan dealerships before one finally found out. They initially replaced the fuse, added freon, replaced blower fan but none of those helped. The last Nissan dealership I took it to found out it was a broken relay. I got charged around $200+ for replacing the relay plus labor cost.

They replaced the condenser.
