Either the electric motor has an open (is bad), or the switch at the latch is not sensing that the latch is articulating with the motor's latch loop.

Try to replace the motor with one from a salvage yard. Check continuity of the motor, there should be continuity if you probe the two leads that lead to the motor when the harness is disconnected.

Good luck on this repair.

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)

Trunk pull down


Inoperative trunk pull-down motors are very common on Cadillac. The sytem simply needs to be diagnosed. The most common causes are bad switches on the latch assembly (there are switches on both the body part of the latch and the trunk-lid part of the latch) or broken wires inside the wiring harness that connects the body with the trunk lid. Proper diagnosis required.

Where is the anchor hook i the trunk of a 98 caddy deville so i can bypass my automatic trunk?


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.

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.

Where is the fuse for the trunk of 1997 caddillac deville?


If you are referring to the trunk lid pull down motor, the pull down switch is out of adjustment or bad. It is located on the main car body, not the lid.
