I was driving my car the other day when I noticed that only the heat was working. If i put the climate down to 60 with the AC on it's still shooting out 90 degree heat...Also the sensor that shows the outside temp is showing ----F. It started at 104 and worked its way up to 127F and now it only shows ----F. Is this the Auto Heat/AC Control Unit or something else...Could it also be something as stupid as a fuse somewhere in the car to cause this?


Thanks

 

Check the online FSM, sounds like you've got two failures:

One is the ambient temp sensor, the other would be your "door mode" actuator or motor, which switches the door in your blower housing to either give a/c or heat. Sounds like it's stuck on heat.

There's a diagnostics/error code "tree" you can access right there on your auto display screen, but you need the pages from the FSM to confirm what's failed.
