1995 Cadillac trunk pull-down malfunction

The switch is down as far as it will go. It clicks when the metal pushes it. If I run the striker back up (either by connecting it to the vehicle or by applying external power to the motor connections) the switch stays in the down position until the bottom metal contact flips it up, then it goes all the way up. The switch on the deck lid is securely attached to its connection. Pushing the switch on the deck lid accomplishes nothing, which is the whole problem. I ran an ohm test on the wires from the deck lid switch connection to the motor connection, and they all have good connectivity (i.E, zero resistance from the orange to the orange, red to red and black to black), so there are no broken wires in that circuit. I have ordered a new deck lid switch from Cadillac. Below are pictures showing that the metal tangs do contact and move the switch--when I make the striker move by manually supplying power to the motor.

Youll have to replace the deck lid switch because the pull down unit appears right. You were right to order the deck lid switch thats the only thing left.

One hopes. If it's not that, then there's a bad wire somewhere and I'll need a wiring diagram to track it down.

Almost allways its the switch on the motor. But I have replaced a few in the 20 years at cadillac.I cant see it being a wire. Im sure you have checked the connecter for the deck lid switch. When you push the deck lid switch. The motor should run up and down.I wish I had more for you. Let me know whats up. Gl

OK then. I replaced the deck lid switch. Still doesn't work. Everything is new or different except that the pull-down still doesn't pull down. It will go up. It won't come down. Can't be a mechanical problem since all the mechanics have been replaced. Must be an electrical problem but I can't figure out how the electricity is supposed to flow in order to get the motor to pull the striker down. There's a break in the system somewhere.

Recheck switch at motor insure locking clip for switch is locked. When you push the deck lid switch it should run up and down on its own. Check the wires in the deck lid to the pulldown assy. Remove carpeting where needed. Check the harness at l/side trunk hinge. You will have to do a continuty test from the lid switch and the pull down unit to check for a open wire.I never had this porblem with the pulldown harness. Recheck the pulldown motor for running both ways.I think the problem is the pulldown switch has a bad connection to 1 of the motor connections to go down. Ill get back with you tomarrow.

I HAVE THE SAME EXACT PROBLEM, AND I EVEN WENT THROUGH THE SAME PROCESSES TO DIAGNOSE THE ISSUE, MY CONCLUSION IS THAT THE GEAR INSIDE OF THE LATCH HOUSING, BECAME SEPARATED, IT IS HALF PLASTIC AND METAL, IT WILL ALLOW THE GEAR TO GO UP, BUT NOT ALLOW IT TO GO DOWN, THE GEAR MUST BE REPLACED, NOT THE MOTOR, AND NOT EVEN THE SWITCH, ITS THE GEAR.

Go to the dealer and buy the gear, the plastic housing, and a switch and then just install them. This will completely rebuild the trunk pulled unit.

Sold the car about a year ago. That solved my problem with it anyway.
