I had the same problem with my 02 Envoy. Check to make sure contacts inside the sockets are intact. I had to replace both of mine. Contact were corroded and rusted out.
no
You will need to remove the seat belt bolt on that side along with the screws located at the bottom at the floor of the cargo area.
In 02, the Envoy was a trim package for the Jimmy.. it didn't become a separate model until the next year, IIRC. So, you would have the 4.3 Vortec, and I have some unfortunate news for you - the oil pump is an integral part of the engine. By which I mean, it's inside the engine, and, to replace it, you'll need to pull out the engine, remove the oil pan, and access it that way.
re: 04 Envoy - my service 4wd light came on in the middle of a 10" blizzard. I researched it and took it to Jiffy Lube and had the front & read differential fluids changed. Light went off and has stayed off. Now my "service engine" light keeps coming on - I'm concerned that I may have a crack in the gas tank as I have read many many other Envoy owners have experienced.
i had an 02 envoy and the dealer replaced a module in the door for the auto mirror. I believe you are asking how one should deactivate the auto mirrors when using the remote. You will need to scroll through the menu located below the speedometer and just above the steering wheel. This will give you the options you will need.
