One more problem DIY SELF LEVELING SENSOR anyone!

[ftgambit]

My Car looks like its jacked up on roids, the rear end is up really high, my battery was dead this morning and had to get a jumpstart, the rear end is up as high as the shocks will allow, last thing I heard was the compressor running and then puttered out as battery was dead. Now car is running fine but the suspension will NOT lower the back to the proper height.
If anyone can type up a DIY w/ or w/out pictures on how to replace the self levelling sensors that would be much appreciated
