Not blowing hot air when idling

We have a 2004 Z71 Surburban With dual zone climate control the truck stopped blowing hot air at idle. When you push on the accelerator the truck will start blowing hot air again. that is until you stop at a red light then it starts blowing cold again.

Why does 1 side of dash blow hot and the other cold when ac is on with the dual climate control?


Check the actuator motor on the heater it directs the air into the vents. There is probably two of them be sure to check both. The motor makes the vents move and again directs the air where you want. Hope this helps.

No hot air on driver side. Pasenger side has hot air.


if it has dual zone climate setting it could be stuck in the cool setting. if it is not blowing any air it could be the duct came loose and it is blowing the air inside the dashboard. it will require you to pull the dash apart to inspect what the exact cause is. it could be anything from a bad temp setting switch in the climate control panel to a bad vac line that that switches the air from hot to cold. any other info you could give me may help such as if it is full electronic climate or manual knobs, dual zone, is it blowing any air or just no hot air.

Intermittant hot/cold air from heater


Had the same problem with my Mazda6 awhile back. Took it to the dealer and they found the radiator wasn't holding pressure. They replaced the whole radiator under warranty (WHEW!). Not sure how to check for that kind of thing, but it's a start.

Dual climate control


There is a thing called a blend door, it controls air temp, that is where the problem is, most common issue is the motor that operates the door fails.
