The only problem I've had with the slides on my Windsor is when the bay door switches break the circuit. Most of the time I can open and close each one and the problem is solved. I know I need to adjust the switches on the bay doors but just haven't gotten around to it.
You might want to remove the push-on terminals from each switch and put an automotive fuse between them to complete the connection. That's an easy way to find out if the switches are causing the problem.
