You probably have a leak in one of the air lines going to the airbags in the coil springs, or the compressor has failed to produce air pressure.

The back end is lower than the front end, like the shocks are broken, maybe something about an air shock?

Looks like it.
Go to each corner of the car, press it down as much as you can and let go quickly. The corner should bounce up a little, down a little and then stay at the mid point - that is a 1.5 bounce. If the car is bouncing more 1.5 times or doesn't bounce at all, then the shock at that corner is bad and need to be replaced.

Shocks don't have a valve for the driver to fill with air. They need to be replaced with new ones.

Based on what you describes, the back corners will not press down and of coarse will not bounce - a definite shocks problem that need to be replaced.

My 2002 envoy will not lift back up

Sounds like the air bag pump went out. I replaced mine and got it on line and saved hundreds. It is located just behind the right rear wheel well just over the muffler.Hope this helps.

I have a 2004 GMC Envoy xuv and my rear shocks keep losing air. I think they are made w airbags. I was just wondering if they can be patched up or do they need all new airbags and where can u find new ones...

The air bags should be strong and not leaking themselves. It may be a valve on the bags or the plastic line going to the back that is leaking.
Some soapy water sprayed on the air ride items may show bubbles from where its leaking. Like checking a tire for leaks.

HEllo I have a 2003 GMC Envoy SLT and evey morning the rear end is down practecaly on the floor but when i turn it on the compresor lift the cars rear end back up. I do hear the leak of air in the rear...

well have you determined where the air leak is coming from???? Get soapy water and locate, could just be a fitting loose and a snug with a wrench is all. If this vehicle has an air bag and it is leaking from a puncture or crack in the bag then it has to be replaced, but check air line and fittings with soapy (dish soap ) water first.

I have a 2003 envoy where the rear end is riding realy low any ideas

I had the same problem with my '02 Envoy 4x4; had the soap test done and there were no leaks; also had the air compressor motor checked and mechanics said it was fine. The rear air bags were worn and cracked so I had them replaced. It lifted and rode at the correct ride height for a few weeks.
After having the rear air bags replaced I noticed that it was starting to not lift as before. Had another diagnostic check; the air compressor was not forcing air through the system in order to lift the vehicle. The air compressor motor was replaced. Compressor comes on and shuts off now.
Vehicle is at the normal ride height now.
Rear air bags and air compressor motor were dealership parts; unable to find after market; not recommended to replace with used parts.
I had the dealership to run the diagnostics and had another mechanic to replace the parts. Total repair for bags, motor + labor = $1500

Removing rear air suspension on GMC Envoy

Just behind right rear tire up in the wheel well. Air inlet is inside right rear quarter near the accessory inflator. Compressor runs 3 lines one for the accessory inflator and one for each air bag.
THere are also 2 sensors, one on each trailing arm that senses load and then raises and lowers accordingly.
