Have you tried the trunk lock button inside of the glove box? Greg
Sell the car.
The trunk switch on the dash should still operate unless the trunk release switch inside the glove box has been turned off.
The lock and trunk circuit breaker for a 1994 Park Avenue could be in one of two places. It could be under the dash with the fuses or under the hood with the relays in a distribution box.
Remove the power trunk release, it may be stuck and holding the latch to the open position. I had same problem and found that if I use the key to unlock power lock then closed trunk - it worked.
If you have an automatic release like I had on a 1994 Buick P.A. and it stopped working and would not close, I had to replace the latch assembly to make it a manual by getting a used one from the salvage yard. The trunk still closes today.
It is not located in the trunk it is Mounted on top and inside the fuel tank.
In the Glove box
yes, it does in my 1991 buick park ave.
If you're talking about the release that's inside the trunk, it's there in case you get locked in the trunk, so you'll be able to get out.
There is on the remote , and a safety release inside the trunk if someone gets locked in , but I'm not sure if there is a trunk release inside the passenger area
Call AAA.
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.
