Randall ask me for some assistance on this one.These q-syncs are a bear. You can spend all day and find that one of the reed switches is stuck. You can manually retract the slide by putting the motors in bypass but it will take four men and a mule to do.
Here are a few things to look at.
You probably have looked at all of the links but I included them just in case.
Motors will not run. Check all connections.
Check fuse (F1-F2-F3-F4.) Not likely as these are fuses for each motor
Check that harnesses are connected to proper plug.
Magnetic reed switch for room locks is faulty (stuck closed,) bypassed, or magentized. Highly likely
Room locks are not disengaging,
caused by magnetic switch problem (open) or
faulty room lock.
Fuse blown (Fleetwood circuit #329.) Possibly
The 12 volts at the switch comes from the controller. My guess would be one of the interlock switches have it held out.
Let me know how this works out and I will try to assist you further.
Good luck, Ronnie
