air suspension sinks in back , wiring schemetic help
02-15-2004, 07:11 PM
Have a 1999 Lincoln Navigator and I can not get the back to lift. The check suspension light illuminates. Two wire harnessess seem unconnected on the left rear rail and right rear rail. This may be why. However, I do not see a connector running back from the front to the reae to connect these to. Please advise,. :eek7:

I would guess that the two plugs should go to the air vent selenoids (connected to the air springs). I have a wireing scematic if you need it. Let me know and I will e-mail it to you. My Navi had the same problem. I noticed that there was no signal coming from the computer to the compressor. Once I replaced the height sensor in the rear, all was good.

Air compressor is underneigh your washer fluid tank. Replace it, that will fix it. damn things are faulty.

Thanks guys, i havent been on here forever. Anyways. we have had the compressor replaced 3 times and were getting sick and tired of it. Just as i was about to go back to the dealer and rip them a new one. the battery died so i put a new one in and the back end rose right up. lol The Air compressor was running almost every 10 min like clockwork and it ended up ruining the battery. but ever since i replaced it all was well. its for sale now. 199,000 miles.

You need to call up someone with athorita, and talk to them about the lemon law.
Depending on where you live, they will give you a new navi, or replace it with one of = or lesser value or something like that

If the wiring that is not connected is near the taillights it is too far back to be anything with the air suspension. The Last thing electrical is the hieght sensor. Your pump turns on or not. If not and the pump is good then it prob is the relay. If the pump works you need bags and height sensors.
Can you describe the symptoms in more detail?
