Chances are you have a split in the plastic line to the rear suspension bags - I repaired mine (found it near the left side wheel well under the hood) with a compression fitting purchased at a hardware store - cost about $4 total, plus a few minutes looking for the leak...
A problem has been detected with the air suspension system Take it in for servicing
If the check suspension light is staying on in a 2000 Navigator, it is probably because some part of the suspension is malfunctioning. This could be that the shocks need to be replaced or a ball joint is bad. Either way, it is a dangerous situation.
A suspension check is a review of the parts of an automobile that constitute the suspension system. These include CV joints, shock absorbers, and struts.
A malfunction with the air suspension system has been detected
May be the air suspensión switch isn't on position check on passenger side under the dash must be the switch put in on position
there can be many different problems but it could be a bad relay switch to check it get on the floor on the passenger side and check to see if the air suspension relay switch is on, try that for now, usually if someone uses a jack to raise the car and the tires have to come off the ground,they switch it off, so the height sensors don't mess up. but it this causes the check suspension light to come on.
I just fixed the air suspension on my 2006 navi, we changed the compressor and read the Manuel and fuse number 111 was out. Check your fuse box its one of theo 20's its a long fuse almost like when your pulling a tooth.
AnswerI just got a navigator so I don't have too much experience but I heard you need to disbale the air suspension before trying to change tire.___________________________________________Check Owners ManualIf you dont have one, check related link below...
rear bags are bad or there is a leak going to the rear. you can check at the pump and see if the tube for the rear came off.
If you have figured out where it is leaking from then here is a link to check out. I haven't used these people yet, but I am planning on it if I need to replace the air shocks in the front...
If you fix the problem with your air suspension
You can reset everything in the Navigator by disconnecting the battery - waiting a few minutes and then reconnecting. Of couse, the vehicle will have to relearn how you drive, the trip clock will reset, etc. I have used it to reset the check engine light many a time.
