I bought a 1997 STS with a HG blown and unknown other problems. After fixing the HG with a Timesert kit I found that the rear suspension had a leaking strut. I bought a Arnott replacement kit and put in 2 passive leveling struts with the by-pass. Then about 2 months later the system stopped working again with a code for the leveling pump solenoid was shorting to ground. I checked it out and found out that the solenoid in the compressor was bad. I replaced the compressor from a junk car and installed it. The system worked fine for about a week, then nothing.
The rear is now just not inflated, I never hear the compressor run, and there is no codes. I checked the level/height sensors and they give almost identical readouts at the same height.
Anyone have any ideas about where to look? I need to take the car on a 5+ hr trip one way in a week and a half and would like to have the suspension up and running.
Additional testing I have done:
I have ran the compressor manually to make sure it will still fill the struts (hooked power to the compressor from its wires under the car)
