Problem with the trunk motor running all the time
Hi guys,
i have searched on the board to see if someone had the same problem, but found nothing. Sorry if there is already a post about that
Well last sunday when my wife , 2 of my childrens & I wanna go to a US car meeting here in France (incredible about 650 US cars by the way) my wife open the hatch & close the hatch BEFORE the complete electrical running operation was over maybe this is the problem. Now the motor is running all the time....
here's a video :
video of latch motor
Relay problem ? anything else ??
Thanks for your help !
Chris

Mine did the same thing, the large plastic nut that lowers and raise the whole assembly was completely stripped out on mine. Got a replacement from TDS, and it was as good as new.

Re: Problem with the trunk motor running all the time
You could have a cracked motor housing. its quite common. sometimes when the housing pulls away, it doesnt think the hatch is down and keeps running. best thing to do is take the trunk interior apart and have a closer look. the track guides also get brittle and crumble. there are a lot of posts on on these issues.

Re: Problem with the trunk motor running all the time
Hawks has everything you need to rebuild it or replace it. They have the plastic gear housing and you may want to check out the plastic guide upgrade. It replaces the individual guides with a large one per side and keeps everything better aligned so it doesn't bind up in the future. I repaired my before and it happened again. Since I rebuilt it the second time, with the new design guides, it has worked flawlessly for years.

Re: Problem with the trunk motor running all the time
If I remember correctly there are limit switches that control up/down limits and a wiring plug on the motor assembly. I believe there are 2 or more wire connections to the harness for it to work properly. Either a connection left out or possibly knocked something out of adjustment or flipped a switch.

Re: Problem with the trunk motor running all the time
If it is moving up and down, but not closing, its possible the gear was not installed correctly. The gear needs about 5 or 6 turns and that is about it. If the gear is not in correct position, it will trigger the limit switches too early/late. don't recall which way. First make sure it is even turning, because you will need to disassemble everything to get to the gear. there is probably a small amount of testing you can simulate while the hatch is open.

Re: Problem with the trunk motor running all the time
thanks for your response,
liquidblue : nope it doesnt move up&down. It's not closing even if your put a big 'slam' on the trunk (what i can do before i change the complete unit)
antman89iroc : it seems everything is here, however i just see when i'm doing pic right now i have forgot this ring (who was behind the ring if i remember well)
By the way the housing & gear were both destroyed
here are the pics (the electrical plug was on when i was making the test, not on pics)

Re: Problem with the trunk motor running all the time
what ever you do, don't slam it. that is one of the ways these things break.. I think the ring goes between the housing and the gear. when you screw the gear on, it turn it 6 revolutions. Top Down solutions may have directions for you on exactly how many revolutions to screw it down. Maybe that ring is allowing the gear to tighten as if you screwed it down more than 6 revolutions. Can you hear the motor running attempting to turn the gear? reguardless, that ring is there for a reason, better put it back!

P.S. get yourself a piece of cardboard to rest those dirt parts on and save that T-Top cover for Gods Sake!
