Guys I know there have been several discussions about the DCCV and other failures in the AC system but this one has me puzzled and could use some advice...


Yesterday I returned home from a 14 week hiatus (work travel) the car was fine when I left but when I started it up to come home my ENTIRE dash was blowing hot and not just hot but heated air....

I had the DCCV valve replaced 2 years ago and the circuit board inside the dash has been repaired. I don't have some blowing cold and some hot all are hot beyond just outside air temps... This is definitely air from the heater...

Any ideas???

BTW it's hot and humid here in Ohio!!!

 

Is external air temp sensor OK?

On my car, its reading is on the LCD panel at console bottom, near ashtray.

Cheap part, about $15 from dealer. Behind where front licence plate is / would be, 5 min fix.

 

Okay... Now tonight it's blowing cold again???

I did nothing, I changed nothing it just started as mysteriously as it stopped...

Anyone seen this before?
