OK, so here's the deal. I got ticked at my 94 air ride, so I chucked it for coil overs, but then I saw how everyone seems to know so much about the air ride system, so now I have a problem with the wife's 95.

Front suspension goes to full height and "Check Air Ride" comes on. Rear is fine. Bags are pretty good, hold air for a month when parked.

Took it up to Go Fast's place and he put the Ford scanner on it, and it said Vent Valve, but I wasn't sure if that could be it because the rear still works fine. But, I pulled the pump and disassembled it, checked the vent valve for cleanliness (ie: rust, foreign object) and it's clean. Tested with 12v source, and it operates fine. Compressor runs fine too, albeit a little noisy. Compressor cylinder smooth and clean.

So here's the thing. This literally happened overnight. It was fine one day, not fine the next. I have a hard time believing that both ride height sensors took a dump simultaneously, and that they cough up the wrong code on a scan.

Anybody else heard of this? Help me out before I commit the unthinkable, and yank ANOTHER air ride system out.......
 
Mine did that, it was the drier on the pump got restricted, air could go out to the bags but not from the bags to the pump. I think its a fairly common issue.
 
I just checked the compressor with the drier installed and I believe you are right. The compressor section got rather hot right away from compression, and when unhooked on my bench, I would think that it would just blow freely.

So where can one get a drier for the compressor???
