Drivers side seat will not move forward or backwards (unless i push REALLY hard while having a friend operate the switch) and when it doesn't move it clicks continuously. All the other power functions work. I have removed the seat and the three motors. The brushes look good. I tried to spin the motor by hand to see if the seat would move and it doesn't. I tried to use a pair or pliers on the end of the gear to move the seat and it doesn't budge. Could it be jammed? What should I do? Any help is greatly appreciated! In the meantime i'll be shampooing the carpets as there was a lot of crap under that seat!!!
