Hello:

I have a 2001 Navigator 4x4 - the problem is the air ride - check susp warning light had been coming on intermittently and is now on - I turned off the switch under the glove box.

When the switch is on the compressor comes on as usual when you shift into drive - it runs for a long time, despite the truck feeling like it is "up"

I crawled under today - the rear air bags look totally full - the height sensor is connected to the axle and the floor of the vehicle - nothing looked obviously wrong

I also peeked at the compressor end - again I could see the two lines going into the dryer - dryer looks intact I don't her any leaks and the back is holding air as the switch has been off for a week and the back is still fully inflated.

Any ideas? How can I trouble shoot this? Should I just take it to the dealer?

Thanks in advance

Electrical gremlins can be hard to find. I'd take it to the dealer to get a proper diagnostic done. Might be as simple as a faulty ground
