my switch went out leaving my trunk in the "up" position as the motor never activated to pull it down, but the motor was still fine.
Instead of replacing it i just used two "jump wires" as in wires with alligator clips on both ends and i applied power just long enough to lower to the desired position to keep dust and water out of my trunk you may find this cheaper then replacing it.
if that doesn't work putting in a latch u bolt in place of the motor is possible but a little know how may be required to convert it with lining it up in proper placement etc.
Sounds like you have the same problem I have. I have to tie my trunk closed with a ratchet tie, because the motorized system kept failing and I did not want to keep spending the money on new replacement motors. Then the trunk finally wouldn't close at all and I have been trying to find a trunk lock so the trunk fits into it, but no luck online, so I will try and find at a wreckers. You can just close the trunk, but it tends to break afrer time.
If it's the one where a electric motor closes the trunk for you, you might have to get the new electronic switch by the latch on the car. That's what I had to do.
The 1999 Buick LeSabre was a popular car for its time. The trunk release latch is located on the lower left hand side of the drivers seat.
it is next to drivers side on floor in front, take pliers and pull up on cable, this will release hood latch
Hire a mechanic!
Replace the cruise control switch (the one with the orange light in it) The switch is a push on push off. If the little plastic gear inside the switch breaks off the switch will work like a door bell switch and will not latch on.
To open the hood latch on a 1996 Buick Park Avenue, the car needs to be put up on a hoist or jacked up. Then a long pole is needed to trip the hood latch. The cable can then be repaired for the hood latch before it is closed again.
Use a set of pliers to pull the cable even if the plastic latch is broken...
The door light switch for these cars is in the door latch. It is not visible by opening the door and examining the latch. If the switch is not functioning you will have to replace the latch. I have heard of cases when doors are slammed too hard that the wire connector comes loose.
It's part of the latch assembly, when the hood is open you can see it.
The switch is part of the door latch
IF IT WON'T LATCH WHEN YOU CLOSE IT, THE PROBLEM IS THE SWITCH THAT IS MOUNTED ON THE MOTOR. THE SWITCH HAS A FLAT PLASTIC ACCUATOR.PRESS DOWN ON IT TO HEAR IF IT CLICKS. YOU CAN GET ONE AT A BUICK DEALER CHEAPER THEN CADILLAC,ABOUT $19.00. REGARDS PAUL G
