2003 GMC Envoy stalling w/ AC on when stopping

My 2003 GMC Envoy is trying to die when I stop w/ the air conditioner on. Doesn't do this if the A/C is off.

    If A/C is on when car is started runs fine and doesn't try to die at stops. If car is turned on without A/C on and A/C is then turned on later compressor kicks in and out and motor tries to die when you stop. Pressures in A/C system have been checked and are fine and low pressure switch has already been checked and is fine.

Try turning up the idle ajustment screw also have alternator checked, another solution would be to have your car tuned up weak spark from your coil worn plugs wires etc. not enough power is being produced

When air conditioner comes on the engine wants to stall

Sounds like the idle air control valve is not working or the air journal supplying air to the IAC is stopped up with sludge. I usually try tapping on the IAC with a small tap hammer first. If that doesn't help you may need to give the intake manifold a thorough cleaning

I have a 2006 Envoy, my heater and air conditioner dont blow out the correct spots, when you turn the knob you dont hear a change, but the main problem is my Envoy when slowing will just die on me at a...

sound to me like a manifold vacume problem. your enviroment control is ran by vac and vac leak or low vac will create a stall condition. ck vac. at switch at heater core box. you will notice a vac line that moves the flap to cover core,for ac, or open for heat
,if no vac, ck firewall in engine compartment. you will see a vac line that travels thru the fire wall .trace back to source checking for cracks and breaks.

07 gmc envoy denali ac stopped blowing air, replaced the blower resistor but now still no air comes out, like no powere through... so what next, what module needs replacing?

You have three possible things left, check fuse #35 in the underhood fuse panel, wiring harness going to resistor pack (look for burnt wires or melted connector), or a bad blower motor.

2003 envoy changed battery out and now when i put on ac truck stalls and dies

The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean. Make sure to clean the front and back sides of the throttle body. Also, disconnect the battery during the cleaning process to allow the computer to reset and relearn to the cleaned throttle body.
When you changed the battery, the computer was reset back to factory settings and with a dirty throttle, the fuel/air mixture is incorrect.

2002 envoy battery died - replaced and now wont start on Driver 2 and wants to stall at all stops on Driver 1 - also stalls when the air conditioner is used

Very common problem with Envoys and Trailblazers. For Driver 1 Clean your throttle body with throttle body cleaner while the battery is disconnected. After this is done, re-connect your battery, drive around for 5-10 miles while the computer resets and relearns. Do the driving with the A/C off and the defroster off. Your problem will be solved. I've never heard of not starting in a different driver mode with just changing the battery.

GMC Envoy A/C Problem

I'd remove my idle air control (IAC) motor, and clean it & re-install to see if that helps. Use throttle body cleaner on pointed part of motor (pintle) and shaft , as well as spray into hole (port) it came out of . If it helps for a while, then start to do it again, I'd replace the idle Air control motor.
