INOP Susp Dump Switch - 87FC35
Ron, Alan,

A thought here...are your coaches equipped with the Clippard
12V/pneumatic switches? Our '87 PT has 6 of them. One each for sure work
with the two dash suspension up/down switches. I've replace a few of
them over the past 2-1/2 years. On our coach the Clippard units are
located directly behind the drivers front vent. With the front vent open
and running down the road, they get road debris piled on the the top of
the breathers and they either stop working or give an intermittent
failure when airing the suspension up/down.
