engine will begin to die when A/C is on and car in or out of gear. I turn off the A/C and it runs fine and if it goes dead it will crank back up with no problem.

My 2004 GMC Envoy vibrates when I turn the air conditioner or heater on . It stalls while I'm driving it and it scares me and makes me think that I'm going to break down . I just put a brand new battery in and it still stalls . I smell fumes of gas.
cannot turn on the air or heater the car will shut off
i had this problem for a while( my personal vehicle). The truck would go into reduce engine power mode at first. Turn the engine off and restarts with no prblem. I ignored it just didn't use defrost or A/C. Than as time went on(months)it got cold here in Philly and i needed my defrost.This time the truck shut off. turned off defrost and it started right up and ran normal. i looked for vacuum leaks. not many hoses to check. finally found advice via youtube to remove throttle body and clean it. I used Brakekleen and cleaned throttle plate very dirty. reinstalled and checked. Problem Fixed!!!! Quick!Easy!and Cheap! Thanks Youtube

The vehicle will shut down when A/C is in use, I have not tried with the defrost. I get an alert for low oil pressure and it will stop in the middle of the road. The steering wheel will lock up and I have to put it into Park. It does always restart.
2004 Envoy.. When turned on A/C or defrost engine would stall & cut off. I turned off A/C or defrost, cranked & ran fine as long as both were off. Took to shop; had throttle cleaned. No problem since.
