How do I reset normal travel height on an 88 Buick Electra T-Type with the

auto leveling air shocks? My 1988 Electra T-Type came with the auto leveling rear air shocks. Always worked great. However, we noticed that after a tire dealer lifted the car to rotate tires, the rear shocks went to maximum height, and did not reset to normal ride. I've heard there is some way to reset the auto-level to normal ride height, but I don't know how. This is a really cherry 88 Buick with all red leather and great features. I want to keep it all original.

I do not believe there is a reset switch. Your year model uses a mechanical valve that is bolted(fixed) to the frame just above the rear axle and it has a pivot arm that is attached to the rear-end.The arm probably came off or broke when the vehicles suspension was raised.You will have to lay under the car and look directly above the center of the rear end and see if the arm is attached .If the arm is not attached you can manually move the arm and adjust the ride height.It may have a ball and socket joint that popped off.Once you determine the arm is not attached you should be able to figure out how to fix it.You may want to go to a shop that can raise the whole vehicle without suspending the wheels and inspect the lever .It is best to raise the rear of this car by lifting the rear end and not the Chassis. Good luck!

Like you said, it's automatic. The only thing you can do is release the pressure inside the shocks if there is any pressure left. I would think if everything is working, the controller would have tried to exhaust the pressure. The air hoses come off very easy by squeezing the clip so try that first. There is a possibility that the air shocks overextended when lifted and are now humped. The other thing could be is that the ride height sensor has been damaged and thinks the ride level is low and constantly demands full height. You'll have to look at the sensor and the arm to the suspension under the car to see. The other thing is the controller could be humped and just keep pumping air into the lines for no reason. You'll have to start checking to see which has crapped out. Good luck.
