I have noticed the AC blows warm air until the truck gets going. When I first start it and if I'm stopped at a long red light the air is not very cold. Any Ideas?

 

Mine does the EXACT same thing. I was thinking of installing a fan over-ride switch so it could be forced to run while idling and the AC is on at my decision.

 

Mine is just the opposite. It I'm on the highway moving fast then I'm hot, if I stop and idle, I cool off. Mine has to be topped off with coolant about 2 times a year, very little added, or else it freezes up and will not cool at all.
