This is a known problem with the Remote Control system on Montanas (and others). There is a "failsafe" circuit to keep the user from using the remote switches and the manual switches at the same time. The connections on the receiver in the front compartment only affect the landing gear and stabilizer switches. The failsafe will not provide a ground to the manual switches when the remote system is energized and will sometimes get "locked" in that position.
You can buy a new control unit for the remote system or you can circumvent the problem. To circumvent the problem, join the Montana Owners Club forum (free to join) at www.montanaowners.com and go to the link

This "trick" has worked for many Montana owners.
