I know EAS problems are pretty well documented on this forum, but I couldn't find one with my symptoms. Hopefully someone has seen this before.
I noticed the front sitting a little low in the morning, more so now that it is winter here in New England. No obvious leaks, so I figured it was in the valve block and I would rebuild it at some point. But then the compressor stopped working, and the up arrrow and all of the lights on the indicator were lit but no fault was indicated. I checked all the functions through the connector at the EAS and the thermal switch is ok (12 volts across pin 1 and pin 16), the compressor pumps up the system when pin #8 is energized, readings at the the pressure cutoff showed it was functioning (12volts across pin 13 and pin 18), but the compressor didn't won't work on its own. I lifted the car up through the solenoids using jumpers and let the car sit with the EAS all hooked up overnight. This morning, the front was down a little but when I started the car and shut the door, it leveled itself. The up arrow is still lit, the level indicator lights are all on, and the compressor never came on. The valve block seems to be working, as are the height sensors if it levels itself but it won't activate the compressor. The dash now shows EAS fault, but it isn't a hard fault.
I'm a little baffled. Could there be a fault that prevents the ECU from activating the compressor?
