one day it just stopped doing it's job - I live in the high desert and it's HOT... so this sucks!

It first started not shutting off... I'd have to restart the car and then turn the car off a couple of times before it would stop too. Then, it quit blow cold air, then no heat no cold, finally just hot air.

started to be an issue from not turning off it was wearing down the battery. Finally, I disconnected it... but I need to get it fixed.
