Previous owner replaced all four air shocks. Compressor failed soon after. I replaced the compressor and burned fuse. Rear was not holding air and compressor running too much. I was leaning towards the possibility of air lines not sealing properly and causing leakage...but...before diagnosing
*that* problem fully, I took it for an inspection sticker...and the real fun began.During the inspection, the idiot masquerading as a mechanic jacked up the front of the car, neglecting to turn off the suspension control as required. (This wasn't his only faux pas, just the most serious at this point.)
After this, the right side stayed up overnight and the left side deflated (the front slightly less than the rear). I started it and the left front came up but the left rear stayed down. I moved the car in an attempt to get the system to equalize but it did not. Then I reset the switch and tried again- the LR stil did not come up, and the RF over-inflated. Now the left front and right rear are holding air and appear normal. The left rear is apparently not getting any air at all and is completely deflated while the right front is over inflated- holding it and will not deflate as it should.
Unfortunately, my Chilton's is rather sadly lacking in specific information on troubleshooting the air suspension system. I'd be grateful if someone could provide a few more details on the operation/control of this system.
If I didn't know that the system was funcioning normally (at least as far as pressure being directed to the appropriate components) I might think that the LR and RF air lines had been switched at the compressor. What else could account for this? Only the control module?
And just how much pressure will the LF hold before it pops? Just curious, I know I'll need to bleed it off before I let the compressor run again.
