The outside temp sending unit is located just behind the grill on the left side. The grill is real easy to pop out of it's attaching grommets by pulling evenly on the top...just be careful that once you get the top free that you don't let the grill tilt too far forward or it will snap the bottom plastic tabs that are inserted into slots. Once you get the top free, tilt the grill slightly forward and lift straight up. It should lift free real easily. The temp sensor is on the right as viewed from in front of the car. The top support frame is semi-square so look under it near the radiator and you should see a small short probe sticking through the metal. It's about 1/2" diameter and sticks out only about 1/2". It's actually installed from behind the semi-square frame with a push-through-snap-in-place plastic housing with a detachable plug on the back of it. You'll have to reach behind it...where the fan is and snake your hand in there to pull it out while squeezing the plastic snap-in-place tabs from the front. The wires should be long enough to pull it out to use both hands to unplug it. Now, take it to the dealer (that's the only place it's available unless you find it online) and get a replacement. Be careful though because they'll try to sell you an assembly that comes with a bracket that you don't need. I bought the one with the bracket because there was none in stock without the bracket but the cost was only a few dollars more. Anyway, I think it was only about $25. Reinstalling it was a lot harder than getting it out because you have to twist your hand in a hard way but it just takes some patience to blindly find the hole to push it into. A flashlight might help but probably not. I read on a bulletin board somewhere that you would need to have it re-coded at the dealer but I didn't and it works fine. I think the temp read out on the mirror is a little off but it's close. I also read that the temp sensor is tied in with the A/C so it's important that it functions. All in all it was easy and no tools were needed...really. Hope this helps.

2002 envoy fan clutch siezes


What is the outside air temperature when it locks up? Summer temperatures will cause it to lock up much sooner which is normal. If this is not the case you can get a replacement fan clutch at any auto parts store

2002 envoy outside temp does not register


Its usually a faulty temperature sensor. Its located to the left side of the rad behind the plastic covers. It may be directly in front of the rad attached to center bracket. Its a small black plastic sensor clipped to the bracket with 2 wires going to it. They can be replaced, no recalibration is needed. Sometimes it will appears as 3 dashes (- - - ) on the temp display.

Air conditioner comes on briefly then stops. The temperature gage on the panel which shows outside temperature is inaccurate sometimes giving a display of -27 degrees.


Well the outside temperature gauge is generally not wired into the a/c. The internal temperature is more important but is not displayed as such. The 'internal' temperature sensor is used to regulate the a/c blending door and blower speed.

When did the cooling problem start?

Ac on 2002 envoy not working. temp on inside says 50 when it is hotter outside.


Ambient temperature sensor is not reading correctly. This will affect whether or not the a/c can be turned on.

Gmc envoy 2002 recomennded oil type?


The overwhelming response on GM Envoy forums is Mobil 1 Synthetic motor oil.

The recommend includes using Mobil 1 0W-40 all year. It will give you outstanding protection at low ambient temperatures as well as at high operating temperatures.

Envoy enthusiasts also recommend K&N or Mobil 1 Extended Performan oil filters.

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).
