How do i perform the 2007 Buick Lucerne air suspension reset?

To reset the air suspension on the 2007 Buick Lucerne first make sure the switch is on (under the passenger side dash board). Next check to make sure the relay is good (black little box under the right front bumper there are two switches/sensors 1 is behind the left front tire the other is up behind the spare tire. If You take the spare tire off it will give You tons of room to work with. The sensors look like MINI shock absorbers with black rubber and can be compressed and pulled easily by hand. Moving those will simulate the suspension going up and down and should trigger the compressor. If the compressor doesn't come on (and all the above is fine) it means Your compressor is bad and should be replaced.
