I have an 05 DeVille with of course the ride height air suspension. I am not happy with the height the car rides at. I want to raise it up just a little. I have read that you can adjust some nut or something. Can someone break down in english what to do, if possible. And can you help me locate the ride height sensor? Thank you for your help.

 

You could try to adjust sensor attached to rear control arm (RT) I think. It won't be much. no adjustment for front. Car has air shocks in rear not air suspension.

 

One option is to replace the air pump with a manual air line. In other words, instead of the factory air pump (which is prone to fail due to excessive use), put a line in that has a valve similar to a tire valve. That way, YOU adjust the ride height with a separate air compressor. When the ride height goes below a certain range, inflate as needed.

Years ago, my dad owned a nice 1984 Buick Riviera, which is similar in body style to the Cadillac Eldorado (but the engine is FAR more reliable than the infamous HT4100 in the Eldo). One of the previous owners did just that: removed air pump and installed the line. When the rear air shocks were low, I took it to the gas station and inflated, problem solved for the time being.
