The trunk wont shut and latch on my 1989 lincoln towncar, what do i do?

sound like corroded connector at fuse panel or a shorted wire this is a job for a professional mechanic

I have a 1991 also and when I first got the car,sometimes my trunk would not close.It has the electric closing feature also, Sometimes the latch stays down and doesnt come back up after you open the trunk.On my car, all I do is put my palm on the latch and push down on it and it comes back up every time. Its a quick and easy fix,,see if it works...good luck...

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.

auto trunk latch is stuck down try putting key in the lock hole and opening the trunk switch maybe it will rise.

Check the fuel pump shut off switch that is located in the trunk by the left hinge its in the owners manual also.

Did you reset the Inertia Switch in the trunk.

under the trunk lip (directly where the latch goes into the lock jaws; remove the carpet so that you can see the side of the trunk latch; on the latch jaws (bottom) is a switch that contacts the latch (top) this switch is broken or, mis-aligned it opens (stops the trunk motor) when the latch contacts it.

check the bolts that hold the motor assembly on. they may of came loose or are broken.
