SOURCE: battery removal on a 2004 GMC Envoy

The battery is on the right side behind the fuse box. You need a metric set to undo the 3 screws. Theres one that attaches to the body, one to the bar that goes along the top, and theres one on the left side below the vacuum hose and air induction. After you've taken out those three, you should lift the whole thing out(battery and shroud) together. It's hard to take the shroud off before you lift the battery out. After that, you have to pry the shoud off the battery. The two terminals in the back make it hard. Then just go to any auto parts store and they'll give you a new one.

SOURCE: 2002 gmc envoy shuts off when i turn on the ac whil ideling

If it does it when idling I would suspect an IAC motor (Idle Air Control). If it is opening too slowly the added air the motor needs will not be supplied fast enough and the engine will kill.

It could be other things also but this is where I would start.

2004 gmc Envoy HVAC system AC works great for about 20 minutes then just starts blowing hot it's the digital climate control if you let it sit for a while it runs great for 20 min then blows hot again

Rule one thing out.... make sure you're coolant reservoir is full

The compressor has a thermal switch, if it gets too hot in the engine bay, will turn off, then back on when it's cooled off.

My 2004 gmc envoy is giving me ans oil pressure low warning and then shutting off my engine

It needs to have the oil pressure manually tested with a mechanical pressure guage. If good oil pressure is found, you most likely have a bad sending unit.

The air conditioner has 5 speeds and it will not turn on until its on 5

Sounds like the blower motor resister. I believe your's is located right there at the switch and comes as a complete unit (don't quote me on that though). Common thing. I hope this helps and good luck.
