My rear air bags did not air up for me after I jack-up our Class-A Gulfstream too high using wooden blocks so the back tires were a couple inches off the ground. Underneath the rig between the wheels, there is a rod with an elbow (shaped like an "L") coming-off the driver's side airbag and going to a controller. Apparently this rod helps the air bag controller mechanically know how high up or down the aisle is extended or tracked from the chassis. In our case, the RV had been jack-up so high (on wooden blocks so the wheels were off the ground) to get it leveled, the normal shape of the "L" rod had gone to a straight line (or "I"). When we let the jacks down the rod reversed itself to a "backwards L". The "on-shoulder of the highway" solution was to jack the RV back-up on blocks until the rod was straight and use a broom stick to guide the rod to go back into its normal position. Watch out, the air bags with "Suddenly" inflate with a "loud pop". We have never jacked the RV up the high again. I hope this help you.
