My hatch isnt moving anymore, it is stuck in the down position now and before was grabbing but not closing all the way, i pulled the plastic away form the back and was looking at the wires, does this whit wire need to go some where?

also has anyone else had this problem?

and now it is not cycling at all

Thoughts?

 

The white wire with a small black connector ontheend is not connected to anything on the 1986-88 pull down units. GM began using it some time in the 1989 model year to turn on and off the rear hatch light. In that case it connected to a black with orange stripoe wire to provide a switched ground to the light. Yours has a manual switch for that light.

Now to address your problem. First unpulg the blue wire from the red with white stripe wire and test it for 12v. If it tests good, then it may simply be that you need to re-set the pull-down unit. Here's what may have happened. If the pull-down unit is stopped midway on the down cycle it will not cycle up until the unit completes the down cycle. This is done by reaching in with your finger or a screwdriver and pressing on the striker-sensing switch. The switch is mounted to the side of the latch facing the front of the car with a single 7mm hex-head screw. You'll see a small paddle that is pressed by the hatch hook when it latches into the latch. The pull-down unit should start when you press that switch. When it reaches the end of the down cycle you must hear a CLICK which is the sound of the reversing switch being tripped to end the down cycle. Release the striker-sensing switch and the unit will cycle up then CLICK again to end the up cycle. Your pull-down unit should now be re-set and ready to work properly again. If the guides are bad or the clear plastic motor housing is cracked it will cause a mis-alignment and cause these sort of problems you experienced.

Took apart the pull down found out the plastic was cracked and stripped the gear, going to repace and see if that fixes everything. It was working great before this happened
