How to replace pull down trunk 1995 Cadillac Deville

Hello James Squyres,

Of the 33 TSBs (tech service bulletins)...

I found nothin on your issue...

Going to the vehicle drawings... (I'm guessing you are considering keeping this beauty)...

Get the FACTORY+WORKSOP+MANUAL... I HIGHLY
recommend for drawing (exactly this issue) and easy secrets to get through those nasty UNIQUE Caddy tasks.. that NO body but your friendly CADDILAC Club might ALSO know...

Nevertheless...
your drawings are presently available on one of my favorite sites "BBB Industries: (see below, registration required).

Perusing the drawings...
The only source not shared with your manual ignition source appears to be through your "TRUNK RELEASE" function.. is sourced (without the ignition) through "THE TRUNK LID LATCH SWITCH"... (ground source).

I am thinking LATCHED (totally defective, replace) contacts there would cause your problem...

BUT... on further consideration...

The drawing show a total TRAVEL of the un-latched lock should completely open the ground circuit... reversing POLARITY of the motor and ready it for the LATCHING sequence...

To me...

It looks to be the trunk lock TRUNK-LID PULL DOWN MOTOR STRIKER SWITCHES... failing to release (change polarity) in the UP position...

Replace the "TRUNK-LID ADJAR" switch.
Everything SHOULD come up peaches...

As to why it is not an issue with manual control...
I'd need to be there with a Volt-Ohm Meter

(perhaps we could dialog)...

Happy hunting...

8/11/2016... post week-long silence

So... 9 DAYs later

little more dialog is not acceptable (?)
I'll go to my monolog:

If you don't know how to run a Volt-Ohm Meter
I'm wasting your time (GOOD DIGITAL $10).

Because of the POLARITY REVERSAL (to push the latch up (when radio-released))...
IS A GROND START SEQUENCE..!!

It is not reasonable to look beyond the mechanical contacts (which I ALREADY) noted... previously.

The full open motion
(at the end of the open cycle)...
Should push the contacts (to reverse polarity)... STOPPING THE UPWARD DIRECTION...
The battery contact (close sequence) is a BATTERY START SEQUENCE) is triggered by gentle push of the trunk lid into the LATCH.

It the travels down tightening the trunk-lid into place... and reversing the MOTOR POLARITY again at the FULL CLOSED POSITION

The ONLY thing that can keep the motor running is bad contact in the release switch... or (somebody) HAYWIRED it.

It would HAVE BEEN be nice to know if you UNDERSTAND the electro-mechanical nature of your lock assembly.

HAVE you done any rewiring (HAYWIRING) would be the PRIME CONCERN...

ELSE... It is the trunk latch contacts.

When last I looked ... those parts were still available...

and having spare parts for a collector quality car cannot be that DISTASTFUL...

I'd give it a TRY (I'm just saying)

There's a motor that pulls the trunk lid down after it latches. The motor is under the latch on the body side. to test it, push a philips screwdriver shank into the latch like it was grabbing the trunk pull down motor to see if it triggers the motor to operate

check your deck lid release lever or trunk release button power supply inside your glove box . the trunk should open up with no problem. you may test it by hot wiring it if you have to,

Thjese are kind of tricky systems #1 if someone has slammed the trunk closed this can break the motor drive transmission housing it is plastic #2 this system uses a limit switch so as the motor rises from being open it stops at the top and clicks the reversing switch then when it closes it latches against the pressure switch that starts the motion. ALL THESE SWITCHES ARE OBSOLETE only can get used but used on Oldsmobile (land yacht) 98 and cameros,firebirds hatch backs.

the motor for trunk is bad, or motor needs a little help !!

Hello: The electric pull down assembly is the hook for the trunk to latch to. If the pull down assembly is not broken the a pull down switch may correct your problem, it is mounted on the side of the pull down assembly.

my caddy had same problem, but instead of fixing it i just bypassed the pull motor all together. its a realy easy fix just detach the anchor hook in the trunk and move it up one position now the trunk works like any other cars trunk with out electronic assistance motors

latch mechanism is probably motorized. Gently pushing the trunk lid down slides the lid/latch bar into the mechanism. this pushes a tab inside the motorized latch and the drive motor pulls the lid down tight and secure. you may be able to test the latch mechanism by sliding a pen or screwdriver into the latch groove to simulate the lid coming down. if you see the motor drive engage, and pull down the tool, you at least know this is working.

Try spraying the inner portion of it with some WD40 or similar lubricant. It sounds like something must be stuck. After you spray it, keep working the key and pushing the remote until you get some results. Good luck. Let me know how you make out.

Ok, you have an auto trunk opener/pulldown. The battery is dead and you opened the trunk with key. SO, now here is what happened. The trunk pulldown motor and latch did not go up as it normally does, in order to catch the the trunk lid as you close it. Connect a battery charger to the battery or put jumper cables on with another car. It should raise. If not flip the little lever on the BLACK switch near pull down latch.
