My 2000 expedition will trip ck susp light when idling sitting still for about 4-5 minutes, during this time compressor cycles on / off before tripping light.
Most recent condition is that when riding down the highway the ck susp light will come on and the rear susp will drop slowly in about 3-4 miles while traveling @ about 60mph.
I can start vehicle on level ground and it will lift up and maintain height, if I put weight on each corner the compressor will cycle on / off as weight is applied then removed.
Vehicle will sit all night and not drop. I see 3 height sensors one on the rear susp and one on each front and they are properly connected.
Any advice on troubleshooting & testing to determine faulty part would be of great help.
Thanks!
