I'd concentrate on IAC (idle air control,)motor, or AIS (automatic idle speed) motor. I believe on your vehicle, it's probably referred to as IAC motor, but either way, same thing, they control your idle during load conditions such as your experiencing. Have had good luck just removing it & cleaning the pintle on it & port (hole) that it comes out of with throttle body cleaner spray. If it cures it for a while, then starts to act up again, replace it. Should be mounted at front/side area of throttle body. be careful not to damage, or lose, "O'" ring at the base of where it mounts to throttle body. If you look the part up online at autozone, or pep boys, you'll know what to look for if not familiar with it.

Car idles down when you turn defrost on


Check that you car is not climate control as this will turn on the ac compressor as well as the heater to give you controlled temp in the car. If that is the case the idle speed sensor and ambient sensors in the cpu may not be doing the job as the engine speed should increase to compensate for the extra load of the compressor. Have a fault code reading done.

My envoy idles up and down when i turn my defroster is on


When you place your controls on defrost it turns your air conditioner on - depending what the heat level is set on the air conditioner will cycle on and off to regulate temp. Anytime the A/C runs the idle sensor will bring the idle up

Hello my name is fernando i have a 2002 gmc envoy im having a problem with my car took it to shop and they cant find the problem wen i turn on heater or ac the car idles up and down then turns off as long...


Easy one. Probably does this with either your A/C on, and OR your de-froster. The de-froster uses the A/C to dry the air. You must of either put a new battery in recently or disconnected it. Clean your throttle body with throttle body cleaner while the battery is disconnected. When finished drive around for 20 minutes or so with all accessories off. At this point your computer will re-learn a properly functioning throttle body. Your computer learned some bad habits with that dirty throttle body, so when the battery was disconnected for one reason or another, it thinks the throttle body should be functioning properly, which it is not. I'd find a new mechanic, this is a very very common problem with Envoys and Trailblazers. If you decide to do it yourself, it will cost you just a bottle of throttle body cleaner, about $7.

When you turn on the heat the vehicle idles up and down then it cuts off


Check for a vacuum leak! It must be bad enough that the idle air control cant keep up with it and the engine stalls.

Good luck and be safe!

Cuts off when I turn the heat on. when the truck is idling or stationary and the heat is on, it will shut down. However as long as I am driving everything works properly.


I would guess your battery cables are loose or dirty, either at the battery or on the starter or ground. Either that or your alternater is on it's way out. It works fine until the AC pump cuts in,which takes a lot of amps, and it kills the engine.

Replaced battery on 2002 gmc envoy. now it goes dead when air is


your alternator may be the problem here. When the AC is on, the motor has to work harder, and the fans need eletricity to spin (unless they are powered by a belt, unsure). If the alternator can't keep up the battery will die.
