Thank you to all why replied so far.
Since Racerguy has a 97 Endeavor and we have a 98 chances are they work the same. There is a red light next to the switch, I have never seen it lit up. I never thought of a connection between the leveling system and dumping air.
So in the morning this is the plan of action. Measure the distance from the ground to step. Push dump bottom for 30 seconds while in acc, and with leveling system on Measure again. Start engine and let air pressure build up. Measure again.
Does this make sense to anyone?
Thanks for any input.
