I have a power swivel seat (59)that i have installed in my 1960 Windsor coupe

Problem is the seat goes up and down, tilts fwd and back, but doesnt run front to back, is stuck all way forward.Solenoids click for first two ops but dead on front to back.

has anyone repaired these seat solenoids and is there a trick to fixing?? Coil? I have a used motor that dont work but onr

e of the solenoids should work. Looks like a challenge to take apart and change out.

Thanks

John
