Hi I'm new to this forum so I haven't seen all the airsuspension posts.

I have a year 2000 Lincoln navigator and the air suspension is acting strange i want to know if it is normal or not. 1st I was putting a few boxes of tiles in the trunk around 500lbs and the rear suspension went all the way down there was no rubbing I thought the suspension is supposed to level the car so this dosent happen. When I park the car over long periods of time the suspension dosent lower or anything so i don't think its leaking.Also I don't feel like the car really goes up or down at all I can hear the compressor working after I turn the car on and turn it off the car maintains a normal ride height however, when I park it, it dosent feel like it lowers for easy access also when i put it in drive i stood outside the car while somebody was in the seat and heard the compressor but it didn't seem to go up at all.Also when i brake sometimes there is a lot of nose dive and the rear end comes up and sometimes the car deals with it fine,same story in corners sometimes there is a lot of roll and other times not so much. On the occasion when I'm driving the check suspension light comes on but if i turn the car on and off it goes away.

BTW this car is not a daily driver i only drive it once or twice a week
 
Sounds like it's behaving like a 15 year old vehicle that needs normal maintenance. The "Check Air Suspension Light" comes on when the system has a problem--I had that happen on my 1996 Town Car, it's air springs had cracks. The air suspension does develop air leaks after ten years--more time if you're lucky. It all depends where the suspension or seals have cracks. As you add weight to the vehicle, the cracks are placed under additional pressure and leak. The air compressor runs longer and will also fail unless the air suspension is repaired. Your problem could be simple to repair or costly. You must find the leak to determine what is required to fix this.
