Just took out the drivers seat yesterday....that was fun. 6 hours plus. Wait till you see the damage you can do with a drill and grinder under the body

Well...I can fix that fairly easily.
There is no damage or anything jambed in the rail system that I can see. I have checked one of the electric motors by running a 2 amp and then 10 amp 12 volt dc power source through it. Nothing no movement at all .... Four wires, brown (ground), red, black (postive), white (negative) ? Seems simple..... I will check all motors first. Then what ?
