Climate control problem. I only have hot air when I put the thermostat at 90°. I don't have any cold air from a/c.
Here's a link to a thread I started. You'll learn a good bit.


More than likely your cabin temperature sensor above your left ear is bad. You can try resetting the HVAC control unit like I did in the thread if you have dual zone AC. If you have the manual dual zone then I have no idea. Good luck.
