2003 Navigator - Suspension Suddenly Stopped.

I have a 2003 Navigator, and something weird happened today when I was out driving. I took two trips today, and during the first trip, the truck said "Check Suspension", but everything was working fine.

Before the second trip, however (later on during the day), the truck didn't raise, and the ride was severely bouncy and the air bags did not raise up. I pulled into a lot, and turned off the car, and turned it back on to see if it was a fluke, but no. The compressor(s) aren't turning on either.

I checked all the fuses relating to the suspension, and everything is fine with them. I made sure the suspension switch in the back of the truck is on.

Any ideas on what the problem might be?

Also: I did a search and most of the suspension problems I found here, and on google don't quite match my problem.

Thanks in advance for any help.

You can check the air compressor for continuity. If it doesn't check out then replace it. Electric air compressors do have a life span. I'd also get the system checked for a possible leak, which can lead to premature compressor failure as the compressor has to work harder to keep the air pressure up. If you have a means to get under the vehicle you can check for this yourself. First, get a new compressor and bring the air pressure up. Shut the vehicle off and get underneath with a spray bottle filled with a cup or so of pink/red hand soap. Spray all the air line joints and fittings and watch and listen for small bubbles or any signs of an air leak.

I don't recommend driving without the air suspension bags inflated, as you can tear the bags increasing the repair bill. You may get lucky and find a compressor at a salvage yard, or check out Ebay or other online stores before purchasing one at a premium price at the dealer.

It sounds like the airbags got holes or cracks in them causing the compressor to work over time therefor killing the compressor. Air suspension is never truly 'fixed' the only true fix is coilsprings. I would recommend going to strutmasters.com and taking a look at the conversion kit. This converts you from air to powder coated, American made, steel coil springs that are guaranteed to last the life of the car. I posted the link below if you want to take a look.

Good Luck!!!
