Picked up a 91-92 Plastic Style Hatch Pull down out of a 1991 T/A at the junkyard.When I hooked it to power it went to the full up position Problem is i cant figure out how to make it go back down.Usually i just push the button in the latch slot but it doesnt do anything.Anyone know how to remedy this?I have only run across this problem once before with a similar 91-92 pulldown unit

 

As far as I know there is a switch in the pull down unit that triggers it.

 

if i remember correctly there's a little switch looking thing somewhere near the bottom that needs to be flipped. i had this problem with mine too. if i can find the old motor i'll let you know exactly where it is. also, if you haven't rewired it yet, watch out, there's a black wire that for some reason is a power wire, i accidentally grounded that and blew up way too many fuses trying to figure out why, haha.

 

Here is a breakdown picture of the hatch motor assembly. The switch that you have questions about is the item numbered #17 and is circled on the left side of the picture.

 

I am quite aware of that switch and what it does.Problem is when i tried it nothing happens except i get a slight buzz from my power supply.

 

One thing I noticed between the 91-92 style was the metal loop that's on the hatch itself is actually thinner. I tested one out of a 91 and it won't lock with the older loop. Hope that helps, I'll be doing the same thing to my 89.

 

Is this the reversing switch?That is what i usually push to get the motor to go back down but it isnt working.Just makes a buzzing sound on my power supply

 

Yes that is a reversing switch, push down on it and the motor goes down. Release it and the motor goes up. One thing that you might want to look at is the motor mount housing. Mine was cracked and broken around the screw attachment points. It would pull the hatch down to a certain degree but not all the way and almost burned up the motor. Another thing to look at is just replacing that switch.

 

Anyone have a part# on that switch and how hard is it to replace?
