Entry Step problem

[fred89sp]

Under Files check Air Step. This is information I put together to fix
the step on my 89SP. I suspect it applies to the 91SP but check to
see if you have any prints for the step in your blue box to see if
they are the same.

By way of supplement, puncturing the wires permits moisture to enter
which will rot the wires and cause failure down the road. Perhaps
sealing with silicone is the answer. Also my cylinder seized up
eventually. Without air pressure it should move freely, if not it
must be replaced, it cannot be rebuilt.

It is frustrating to trouble shoot this system. After checking the
door switch and the cylinder, the prime suspect is the valve assembly.
With the history you give it could be the cylinder. The positioning
of the mercury switches is also a problem. Suggest you take some
digital photos of same before you start.
