The air flow,is changing mode,looseing air flow, and getting blended air too?Is the flow going to the defrost mode under acceleration? Maybe looseing vacummn to the doors and the water valve if it uses vacumn to change modes.Might be electrical problem.Check fuses in panel.Do you here a hissing in the cab,near the control head area?Or the brake booster?Do you here a scraping like the a/c clutch is slipping?

I have a 1998 Chevy lumina 3.1 that when you started it starts at idling in the red zone if you try and t hich the gas it automatically kills the engine so it doesn't blow up


You have a Vacuum Leak that is sucking in AIR and that is causing the Increased RPM.

Does it slow down after it warms up?

I once had a Idle Air Control that was causing it on a 3.1 and when I replaced it, the Idle went back to normal....

2010 mustang air conditioner blowing warm air and hesitating


Very strange.
Usually the ac compressor cuts off if the computer detects a major problem with the engine such as a power loss on more than one cylinder.
And if that happens the computer should store trouble codes for the issues.
Is the check engine light staying on ? Will the ac work if the engine idles ?

Car blows warm air when idling


It sounds like your AC unit could be overheating or even damaged.

AC units have a sensor that will turn them off automatically to prevent damage from overheating. If there is an insufficient amount of air flow, the unit will heat up, and then eventually turn off.

When the car is moving, more air is forced over the unit, likely keeping it cool enough to run, however, when the car come to a stop, it loses that air flow, and quickly heats up. Thus, the AC would work while the vehicle is in motion, and overheat and stop when the car is stopped and idling.

However, the AC unit could be completely blown. The cold air while moving could be just a case of air being forced into the car. Think of a house fan, the fast the wind blows on you, the cooler it gets.... Thus, it could be an illusion that the AC is working when car is in motion, when it really isn't.

Hope this helps.

2005 sante fe a/c blows warm air when idling @ stop light - works ok at higher speeds


You need to recharge your a/c, and check its fuses. It's not blowing cold air at all, even when you are driving, because when you are driving it is blowing in the cooler moving air from outside your vehicle.

2005 Pontiac Montana SV6 heater blows cold when slowing to idle


How cold is it there and does your engine cool down any while going slow? If it does it may mean you need a hotter thermostat installed, My first thought would be to check the coolant level in the radiator and the coolant reservoir! Hope this helps and Merry Christmas

Map sensor


that is not a map sensor(mass air flow) it is a barometric switch also know as a mps(manifold pressure sensor) if your vehicle idles fine but when you try to accelarate. i have a question? is it a throttle body or a carburator type fuel system?
