I have a 01 Navi and the rear suspension doesn't work at all. The check suspesion light isn't on but the back is so low to the ground and causes the bumpiest ride ever. The switch under the passenger dash is on and everything, can't figure out why the back won't raise. Any help or advise would be helpful. Would love to try to fix it myself , since I don't want to take it to the shop and pay loads of money.:disappoin

first thing does the compressor run - if not check the pump relay - mounts behind the front bumper on the right hand side - 4 wire plug - remove it from its mount and look at the back - lots of them will split open on the back from corosion.
