INOP Susp Dump Switch - 87FC35

[Ron Hazlett]

Alan,
I'm was hoping you would get an answer to your question. I have the
same problem. Both of my Susp Dump Switches are not working. The
switch at the outside door has voltage, I have not pulled dash to
check the inside switch. I am not sure if I am looking for an air
pilot-operated valve (not sure what that looks like) or a bad
solenoid. I tried toning out wires, but no luck. I hope someone
chimes in,as I feel uncomfortable using the bus when things are not
operating as they should.
