With my research with my mechanic also my body shop there appears to not be a manual trip. In this order these went out: rear wiper motor (squirter still works) then actuator lift and finally the pull-down/release module. Are these controlled by a body module? please feel free to reply even if it's a thought or suggestion. Submariner ,BassCat, Ranger what do you guys think it could be. I know it's not a N* but you guys have a lot of knowledge.. Please chime in Ed
