1999 Volkswagen Passat • Automatic •

My 99 VW Passat suddenly started blowing warm air after picking it up from the mechanic. It was in the shop for a throttle body reset after having the battery disconnected while I was replacing some parts. When I first picked it up it blew warm air for 15 mins then cold air for about 10 mins until I got home. I parked it. Next time I got in the car hot air again.
