Electrical prob.

I have a Ford conversion van w/ power seats and a power sofa in back. While moving the sofa forward, the tire jack got wedged between the seat frame and the floor. Something obviously blew because none of the power seats are operational (even in front). The conversion fusebox says that the sofa circuit breaker is self-resetting and located behind fuse box. The factory fuse box has fuse for power seats, but seems intact. What gives?

when unsure if a fuse is bad, test with an ohm meter.
You will have infinity if the fuse is good. the needel on the meter wont move if it is bad.

If all else fails pull the seat and look for damage repair any damage.
