I believe whoever designed this system was shot before a firing squad.

It double reverses to work.

Probably someone said, "Oh, we forgot the cowl motors. Here is the mounting footprint, draw something"

Basic design would suggest not exercising the wiring harness and connections with each movement...until they break.

If you can, have a friend blip the cowl flap motor (open/closed) while you are observing its actual direction of movement.

Once you have observed its movement, and made what will become 'obvious' adjustments on the switch positions, try to secure the wires in such a way that the soldered termination on the motors isn't being twisted and bent each time.

Also, toss in a 2 amp (or less) fuse inline with the motor to save you some grief, should it go past a limit.

Lastly, as I recall,the turbo rear flaps are supposed to be 1/4 inch open when closed.
