SOURCE: Trunk Latch will not pull closed.

The small switch is the trunk by the pull down motor with the flap that depresses down is at fault. That is what you call the truck pull down switch. You can take this part and show it to a Cadillac or Ford parts department sales person and get a replacement for you car. Ford uses the same part for their Lincolns and Crown Vic's. The part is made by the very same supplier for Ford & GM. Ford will sell this part at a much lower cost as well compared to GM

SOURCE: 1996 Cadillac Deville trunk pull

There is a switch that lets the motor know that the trunk is closed all the way. This switch may be faulty or not adjusted correctly. Find the wire that feeds the switch and check it with an ohm meter to see if it is working.

SOURCE: how to replace pull down trunk 1995 Cadillac Deville

The trunk lid pull-down assembly switch, part number 16629927, most likely needs to be replaced. The switch is mounted on top of the trunk lid pull-down assembly motor at the bottom of the trunk. The switch costs about $43. It's easy to replace. Just unplug the electrical connector, remove one Torax-head screw, and pull up on the switch while wiggling it.

To verify that the trunk lid pull-down assembly switch (which is actually a combination of three enclosed ganged striker switches and one lid ajar switch) needs replacing, connect a test lamp or voltmeter between the orange and black wires on the electrical connector. If the lamp lights or the voltmeter shows about 12VDC, then either the connector needs cleaning or the pull-down assembly switch is bad. If the lamp doesn't light or the voltmeter reading is zero, trunk compartment fuse D7 is open, or a wire is open or shorted to ground.

Trunk release works as intended when ignition is off and remote is used. when trunk is closed and ignition key is turned on, trunk opens and latch keeps clicking until key is turned off.

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)

Why doesn't pull down switch grab the trunk lid?

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

1996 Cadillac Deville trunk pull down motor continues to pull electricity after trunk is closed (does not do so when trunk is open). The pull down motor works correctly other than that. Do we need to...

There is a switch that lets the motor know that the trunk is closed all the way. This switch may be faulty or not adjusted correctly. Find the wire that feeds the switch and check it with an ohm meter to see if it is working.

Trunk "popper" quit working, but "pull down" still works

can you still open it through the key? does the pull down motor not work at all? if the pull down still works it sounds like the popper has just gone weak/bad . they need to be replaced after so long. seeing as you should have a keyfob and a button in the car. im assuming that means its the solenoid switch for the trunk release which is a 30 dollar part.
