Question about 1995 Cadillac DeVille

Car won't start-- warning light

On my 1995 Cadillac Deville the warning light next to the "open trunk" button is flashing and the car won't start. I've checked-- the trunk is not open. I think part of the problem is that it snowed heavily last night and water might have gotten into the sensor. The security system thinks the trunk is open. Any ideas?

Try removing the fuse for the security system and see if this will allow you to start the car. If not, you have another problem and will need to take it to a mechanic.

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)

1995 cadillac deville vacuum hose diagram


I have a 1995 Cadillac Deville. The car runs great. When Its cold. As soon as it gets hot, if you turn it off it won't start. And when it does start is has no power and spits and sputters to the point where you have to lay on the gas to keep it running. My husband and I have done everything imaginable to this car and it will run great for a day or two then we are right back to square one. Do you have any idea what the problem could be? Please help/

My 2001 Cadillac deville was hit i'n the front driver side and during the accident i moved my car out the road and parked it to talk to guy who hit me so I turned off my car and got out and later when...


Hello. There is automatic fuel shut off switch. When the car is in an accident like you were. The switch trip and turn off the fuel. There should be a red button in the trunk on one of the side panels. If not, call the dealership and ask them were the auto fuel shut off button is located. Also, it might in your vehicle owner manual. GB...stewbison

1995 cadillac sedan deville with penny in cigarette lighter now car won't start


You may want to remove the penny from the cigarette lighter...

However it sounds as though you should take another minute or two and check all your fuses and replace the ones affected if any.




Good Luck and Happy Motoring

Anti theft system came on dash. shut the car down will not start. 2002 cadillac. i was told 30 differ sensor showed wrong. which sensor to start with.


The SECURITY light is located on the instrument panel cluster.

If the ignition is off and any door is open, the SECURITY light will flash, reminding you to arm the system. To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with the door open or the remote keyless entry transmitter. The SECURITY light should come on and stay on.
3. Close all the doors. The SECURITY light should go off within approximately 30 seconds. If a door or a trunk is opened without a key or a remote keyless entry transmitter, the horn will sound and the lamps will flash for about 30 seconds.

Also can check this and other details in the 2002 Cadillac Owners Manual (page 85 and next).

Hope helps (remember rated and comment this).
