Your vehicle is new enough that I would say one of your components is defective,diagnoses from a dealer or auto electric shop would be recomended.Sounds like your sensor outside is defective.

Outside temperature on rearview mirror is sayin OC on 2002 envoy

Have you used the handy search feature? You would find that this is likely caused by one of 2 things. First, the ambient air temperature sensor may have gone bad. Secondly, wiring from the sensor to the mirror may have gone bad. Either way, you would get OC (which stands for OPEN CIRCUIT).

2002 gmc envoy xl air bag light is on

You will have to be very careful!!! There have been cases where the airbag lights come on because of an internal computer problem. If you go to your dealer, or maybe a local shop, they will have to hook it up to a computer to determine the problem. Not to get too excited, but some people have had the bag actually deploy, so I usually make that known to anyone I help with an airbag light. Hope all goes well, and please be safe.

the a/c will run based on the pressure switch adn has nothing to do with the temp of the vehicle and or the engine.

If the freon is low initial stages you will hear the clutch clicking on and off and when it becomes extreemly low will not engage the a/c clutch at all/.
