Dumb Blonde here, I have a 2010 chevy traverse, dual climate control, the passenger side is blowing hot air when the air conditioner is on. The drivers side blows cold air. Sometimes when I start the car it blows cold out of both sides, and sometimes when I start the car it blows hot out of passenger side. I have already tried to reset by removing fuse and replacing, (didn,t work). I am thinking now I need to replace the actuator on passenger side, so, where is it and, how much does it cost. would it be cheaper to order from the internet, and if so where is a good place to order from. Any pictures or videos would be very much appreciated.
