You don't have the switch between the metal prongs of the trunk latch. As that latch goes
up or down, it either pulls the switch up or pushes it down. Depending on the way the
switch is set the next time it changes the direction the worm gear moves. You have to disassemble the unit. You'll see a long plastic tube that will lead to the worm gear. It will
be filled with a lot of lube. You'll need to use a long thin screw driver or maybe a coat
hanger wire. You have to manually move the worm gear to raise the latch so that you
can get the switch inside the metal prongs. The first time I did this it took me about 45 minutes
of studying the unit. The second time I replaced the corroded switch it took me about
30 minutes to remember the trick. Fortunately, if you study the various pieces they only
really fit one way. I'm assuming you bought a replacement switch for the one that gets corroded. They cost about $35. I lubed all the electrical connections of the wiring harness with dialetic (?) cream, filled those little holes, and covered with electrical tape. I hope you don't mean you
bought a whole new motor. Hope this helps.

P1237 fuel pump driver module

Have you checked the fuel shutoff switch? it's a safety device to shut off fuel flow in case of severe front or rear impacts, but sometimes it just trips for unknown reasons. It's behind the liner on the driver's side of the trunk. Look at the round opening on top: if you can see that the red button is setting level with top of the switch it has been activated. To reset it, push the button back down until it "clicks" into place (usually 1/2 inch down or so). If it has been activated and the button will not reset the unit must be replaced, and it is a dealer only item.

Our 2003 Lincoln Towncar trunk has suddenly began not shutting properly. When it closes, it does not fully close to a seal. Upon our troubleshooting we feel the mechanism which brings the trunk to a full...

Once the lid is latched there is a motor that pulls the latch assembly down to finish closing the lid.

I would check the latch mechinism make sure it's not moving around on you like the bolts have loosened or that anything is bent. Also there is a switch in the mechanism that activates it to finish closing as well, open the trunk and close the jaw on the lock with a screwdriver or something similar, and see if you can hear the motor run, if not I would place blame on the switch or the motor itself. And as always I would check for loose / broke wires or a bad ground in the immeidate vicinity of the mechanism.

I have a Cadillace 1996 Deville which the trunk will not close and the headlights will not go off what could be causing this problem?

The headlights have a Photometer that senses the sunlight when low to turn on the headlights and also shuts them off. Have that checked out. The trunk has a switch on the motors housing by the trunk latch. It has a small flap that moves up and down to activate the switch. replace that part and the trunk lid will return to the locking position as it did before. Ford uses tha same cwitch on there Lincoln's. The company who manufactures these switches has both GM & Ford as a supplier. In fact Ford sells this switch at half the price the last time I purchased one. Take you old one in to match. It will have the same numbers on it and it should cost under $20.00

It wont latch on n shut.

Good afternoon! The cadillac you have uses two switches to control the automatic pull down feature. If the trunk was unintentionally slammed it can break one or both switches. The switch in the decklid (or trunk door)controls the light in trunk and is also a input to the lower switch at motor to signal trunk closing. Even though the light in trunk works this does not mean close signal portion is ok. The limit switch(mounted to pulldown motor unit is the other switch. This switch has a small plastic lever,a even smaller little tab,and has one screw retaining it to pulldown unit. I have replaced the switch on the pulldown unit 90 percent of the time. As i said earlier there is a chance both switches could be damaged. Hope this information helps you!

Trunk wont pull shut.

You have a pull down switch that activates the pull down motor for the trunk lid to close. The manufacture of this part supplies this to Ford & General Motors vehicles. You can go to a Cadillac dealership & purchase this part far cheaper than at Ford. I use to work at a GM dearlership & my neighboring Ford dealer would order this part from me for the cost of mine where less than the cost from Ford. Figure those guys out at Ford. No wonder they don't need a goverment bailout
