I'm not sure how the fuse/circuit breaker set up is on a Forrester. On my Lexington there is a removable panel to the power management box which has the battery cables running to it. Inside the box are circuit breakers and fuses for the heating pads for the tanks, and mini circuit breakers, one for each of the 3 slides on the Lexi.
If you Forrester has some kind of box like this, check for a bad circuit breaker. The slide motors should be protected bu a circuit breaker, not a fuse, as the slide motors work directly off the 12 volt batteries.
The box is made by Precision Circuits Inc, and is labled as a Battery Management System.
