Trunk motor doesn’t pull down
Hi Guys
I need some help. My trunk doesn’t close all the way down. (1989,IROC, Convertible) Here some more details. I replaced the motor and installed back. Installation went good. But when I close the trunk the motor doesn’t pull the trunk down. I have no idea what trigger the motor from pulling it down?
I noticed the magnet mechanizing and I clean it so there will be good connection.
I checked the relay and I think it’s working well (I hear a click when I connect and disconnect power)
I did noticed that I have one wire that not connected. Picture attached. I don’t know where it need to be connected. Any help/tip will be appreciated. (Also if someone have a picture of the wiring in the trunk that will be great)

Re: Trunk motor doesn’t pull down
Does the hatch unit move at all when activated? if it does, you might have to adjust the bracket up or down slightly to make sure it deactivates the switch appropriately. Here is a troubleshooting guide to help you out.

Also, on that page is a wiring diagram for the hatch unit. It's also attached here.
I believe the trunk motor you have in your convertible is from a T-top or hardtop thirdgen. The black wire looks like its powered by a relay to automatically unlock and release the trunk. The trunk motor I have in my convertible does not have that, my trunk only unlocks by a key. It doesn't look like that wire needs to be hooked up for the trunk to operate correctly. I hope that helps.

Re: Trunk motor doesn’t pull down
A few times my pull down motor would activate without the hatch latching, the motor would pull the locking mechanism down. I would then have to fiddle blindly with a screw driver to flip the position switch so that the locking mechanism would come back up. If only the switch was more easily accessible.....
