If you have the motor off, here's how to retime it. Plug the motor to the harness, from the door window switch,run AUTO down until the motor stops. Then hold MANUAL up 6-9 revolutions, I use paint marks on the gear teethto help count. Unplug the motor and count the teeth on the regulator, find the middle and bolt the motor there. You can only get one bolt started and will have to take the assembly to the car and plug the motor and drive it to move the regulator to access the other bolt holes DO NOT HIT AUTO UP OR DOWN during this step. Once the 3 bolts are tight put the regulator/motor unit back into the car. When it's in hold manual down until it stops, then manual up until it stops.
