Navigator leveling system
#2
On my '97 Expy, there was a switch under the dash on the passenger side footwell that would disable the LL suspension. Your '99 Navigator should have one in the same area (looking towards the front of the vehicle the switch would be to the right where basically the floor, the firewall, and the right side of the truck all come together. If you have the owner's manual, the location will be listed in there.
Keep in mind that this will cause a warning light in the instrument cluster to come on.
