Trunk pulldown

[Maurice Gagnon]

The problem I have is when you close the trunk the pulldown does not stop. I had to pull the fuse till I can figure out what I might have to purchase.

Any help on this would be appreciated

Exercise the paddle switch by the motor. make sure it moves smoothly and check it for corrosion. I have had to change more than a few over time. It can be replaced without replacing the pull down motor. 

You can see it in the picture below

When you close the lid does it continue to pull down? or go down, then up, then down?

Yea Rockfangd, it closes then comes up just a little and the cycle just continues.

Yes it pulles it down then goes up a little then brings it back down. It just continues like that so I pulled the fuse.

Ok I believe that points to the switch on the deck lid itself. Open the trunk and look for the switch next to the latch on the lid. 

You will see the switch without removing the carpeted cover. But to verify that switch is plugged in I believe that has to be pulled back a little

If you need parts remember most 82-92 camaro/firebirds used the same pull down motor.

Check www.thirdgen.org  for repair pics/etc.

BTW:  The pulldown motor in my 93 Deville has been disabled in the closed position.

Must have been a prev. owner mod and broke.

It used to kill me bell hops/valet folks SLAM the trunk lid on my Caddys or T/A !

I would say calmly "close it easy...dont slam it!"

Here is a list for the 86-91 pull down motor assembly (thanks to Lon at top down solutions))
and which car/year usage FYI that I asked about above:

Buick: 1980-93 Electra, 1985-93 Park Avenue, 1980-93 Riviera, 1992-96 Roadmaster

Cadillac: 1987-93 Allante, 1980-96 Brougham, 1980-93 Eldorado, 1980-96 Fleetwood Sedan,
1985-93 Fleetwood, 1980-83 Fleetwood, 1980-93 Seville

Chevrolet (Chevy): 1986-91 Camaro

Chrysler: 1989-91 TC by Maserati

Oldsmobile: 1988-93 98 Regency, 1986-89 Toronado

Pontiac: 1986-91 Firebird, 1985-92 Grand Am

So if your parts yard hunting for a hatch/trunk motor assem. you know which cars to look for.

OK so if I find that it is connected what would be the solution?

manually manipulate the switch with the lid up. Should have spring tension. If you push it up the latch should stop IIRC. I think the trunk light is tied into that switch as well. I will check mine tomorrow. If that does not work or stays on all the time I would replace that switch

Thank you so very much for that bit of advice, I will check that out and let you know

OK so it does have spring tension but when lit is closed the motor still runs

[rockfangd]

Ok. 

Have you verified if trunk light works properly?

On mine if I push the lower paddle at the pull down without pushing the one on the lid it just keeps going up and down.

Once I push up on the lid one it bottoms out and clicks.

Trunk light works with the one on the lid, which is why  I asked that first

[Maurice Gagnon]

Yes the light does work but thats it. Now last time i checked the trunk closes but the motor keeps running and the trunk lid does not move.

[rockfangd]

Ok. Please humor me on a hunch here.

Remove the trim at the pull down motor.

The paddle switch is secured to the pull down motor with 2 screws. Remove the paddle switch, Carefully inspect and clean its connections (to the pull down motor).

If you can ohm test the pins to make sure none of the contacts are broken.

Verify the small switch (flip) snaps up and down properly. It is located at the latch on the pull down motor. When the lid switch is closed and the pull down pulls the latch down, that should flip down once bottomed and stop the motor. If the motor is continuing to run I would be suspecting the switch is not working properly or lid latch is out of adjustment, which would not allow the pull down to bottom out.

I mention inspecting the paddle switch though because 9 out of 10 of the pull down issues I have come across end up leading to that 

Here is a video that may help a little bit. To show better view of the assembly. I do not recommend the repair though

 

[Maurice Gagnon]

OK I just checked it out again. It is not pulling all the way down all the way. Now that little piece below the paddle switch in the trunk should go all the way down?
