2004 Tiffin Alegro gas engine LOW milage.
Emergency Brake on. Ignition to ACC. House and Veh Battery full charge. LEVEL NOT IMPORTANT.
Neither front nor rear slide will open... assume no power.
At rear slide switch. EXPOSE. Run 12V positive wire from house battery. Touch pole #2 to exposed 4 plug/contact switch. Press open and it works. Front slide now also works. Can also send 12V positive to under bed slide motor... everything works.
Once energized will continue to work... until the next stop. Sometimes will work even then.
When something works sometimes and does not work sometimes not an easy concept to resolve.
Fiddling with ignition switch many time not a resolution. Parking brake on or off many times not a solution as simply giving mementary power to switch should not resolve with it working with momentary removed. Should not work at all if that was the issue.
Must be a simple answer.... like it was a cludy day...
