In this video, I am trying to diagnose and adjust the rear air suspension sensors on a 2003 GMC Envoy. The ... images for envoy where is the air suspension switch

This is a very complicated and expensive system to maintain. I would strongly recommend doing a air suspension conversion on your Navigator and be done with the problem forever.

Have you checked the height sensor ?

One of the AIR springs is punctured.

I am sure you are not a dumb woman.
The parts on this site are for the '05 Navi.

The two shocks they show have a small "air bag" on them. When you hear the pump running they should be filling up with air.The line should be connected to all of them to fill each air bag.
Next time you try it, have either yourself or someone else stick their head near the bottom of the vehicle and listen for leaking air. So either one of those is damaged or the line has a problem.
These may help too?

If you lived in San Diego, I would come over and help.
Sorry.

is it doing this while driving or while parked?

you need to check your real axle sensor it may have come loose or broken

There are level control sensors they look like little arms (with joints like your elbows) mountesd on lower control arms. They may be at fault they control the height and turn the pump off when the height is reached. try adjust height first before you replace, they can be adjusted. Good Luck
