Air suspesion - acting strange - 98 Navigator
Welcome
Small question about air suspension in Navigator.
Previously I owned the Range Rover (2 actually), so I'm aware how the air suspension works and what to look in case of failure. However...
My Nav, when not used a few days, stays high, do not drop, so I assume that airbags and valves are ok. But:
- when driving, the compressor turns on rather often - maybe every 2-3 minutes, and continues to operate for 1-2 minutes...Then goes off, and after another 2-3 minutes turns on again. When driving longer distance - say over 20-25 miles, the 'check susp' lamp is coming on on the cluster (car still is acting normally - no dropping). But when I stop and start engine again - this light disappears again. My theory is that compressor has too much work and gets over heated... But it's just the theory
- when the compressor turns off (while driving), I can hear from the compressor short 'puff-psst' of the air - the same kind of sound like you can hear from the bus or big truck from the air break system. It sounds like it was over pressurized and releasing some air.
- just after the Nav is parked and engine turned off, I can hear clicking sound (that's normal), and then long 'ppssssssss' of the air, coming from the front passenger side (can't tell if it comes from under the hood or from behind the right wheel). After 15-20 seconds, the Nav is 3 fingers lower on the passenger side than is on the drivers side (the wheel arch is 3 fingers closer to the tire). And it stays in this position, doesn't drop further.
I know, that when parked, it should drop a bit ( 1 inch?), but shouldn't that be evenly and not just one side?
I ordered the appropriate manual on dvd, but maybe you would have any idea?
