I have a 2004 Silverado crew cab with shortbed. It also has the dual control option for the passenger and driver. The problem is with the A/C - the driver side is cool while the passenger side blows hot air. What do I need to do to fix this? Thanks in advance.
I have a 2005 and my # 4 setting on ac doesnt work
Hi,
May or may not help... I've had ongoing issues with my heater/ac, where it's like a vapor lock or something, sometimes the selected vent etc. doesn't work right, etc., like the vacuum control is f'd up.
I topped off my coolant, and things cleared up. Air in the coolant lines???
Hope this is a cheap fix for you.

Same model, same problem. Unless the passenger control slide is all the way down, it blows warm air. When all the way down, it blows cool air, but not quite as cold as drivers side.
same problem. Turn both sides down if on heat and have patience. It will self correct.
My 2004 silverado blows cold air on driver side hot air on passenger replaced control panel did not help i have dual control
Air is cold on driver side...hot air no matter what the setting for the passenger side. Really leaning towards it not being a ducting issue, but perhaps a bad temp. switch? Can't think of much else it could really be...anyone with more insight; would be good feedback!! Thanks!!
Mine does the same thing, A/C works fine when you turn it on and drive down the road. Starts blowing hot air all of a sudden, not just outside air, but heated air out of the driver's side vents. I tried replacing the A/C control unit, then purging and recharging and neither solved the issue. Anyone figure this out?
