Trouble With Suspension Air Bags Sign In

2004 Buick Rainier - Rear weight management air bags are fully inflated (with no load on vehicle) and will not purge.
Pump and bags work and do not leak. I suspect load sensors.
Is there any way for me to purge air from the bags because it rides like a hay wagon while fully inflated?

If you want something till fixed and don't let all air out look up front where most pumps are or better IMO to see a broken mechanical arm/rod something to a sensor for rear air height. Undo and tie it in the middle of full range for now. Turn on vehicle and wait for it to adjust which shouldn't be instantly,

You're going to need a professional level scan tool capable of accessing the suspension module.
