Question about 2003 GMC Envoy
Hi my A/C isnt working to well. I had the system flushed and recharged. The problem i have is its not turing on all the time. And when it does come on it shuts off on its own. Im thinking its an electrical problem. There are no leaks in the system and there is the proper amount of gas. Also when i turn the ac on sometimes i have to keep turing it off and on to engage. Could it be a bad sensor? maybe the clutch? or my heater controls as i have the auto dual climate zone heater. any help would be appreciated. Thanks
The only thing causing this problem thatn i can think of if, will be a defective or intermintant a/c compressor relay, or
if you have the check engine light on or the envoy is overheating
it has a systmes than will shut the a/c system of to prevent engine damage and take load away from engine, so let me know if you have any of this symptoms or if not try to locate the cycling switch most of times it is located on the side of a/c acumulator, if it has two wires only, by pass the wires with a paper clip and if the systems keeps on with no problem the have this switch replace, most of times you don't have to remove the refrigerant to have this sensor or switch replace just turn the a/c on, by oassed like i said and that will keep the pressure low in the system so you can replace the sensor, just make sure it is the low side swich and not the high but if you don;t know how does it looks like i recomend you to buy one and look for the similar on the envoy, any way if you do not need it or not use it
you can always returned with the purchase receip, tht's why i love america always on the customer side, good luck and let me know
