Air Step Diagram

[Wilhelmus Schreurs]

Larry:

I have redrawn a diagram for the 1990 step diagram, is there any difference from that year?

The redrawn wiring isa schematic rather than a wiring diagram.

You could use that for troubleshooting and then give us some indication what you find.

Subject: [WanderlodgeForum] Air Step Diagram

I have been fighting my air step for a year now. All the diagrams
posted on the forums appear to be for earlier birds and do not match
my wiring. My blue box does not have any diagrams that include the air
step.
I have two issues now. The extending cycle works but the retraction
cycle does not work. The solenoid valve is not retracting when power
is applied. That I can fix or replace easily.
The real problem is that no power is coming through the retraction
circuit under any combination of switches and door condition.

I can not trace the wires after they enter the front panel. The air
handlers are in the way.
Any suggestions? Anyone have a current wire diagram?
