Check the thermal fuse in the drop down fuse panel under the dash, left of the steering wheel. It is most likely shot. If so, the electrical door locks don't work either.

Is the thermal fuse under the driver side dash, Is that just another name for a regular fuse?????? Cause, I have replaced the regular fuse, and I have replaced the relay on the passenger side of the car, and my rear window defroster, when I hit it to turn it on, the relay clicks, but the rear defroster doesnt work...... And I have the door locks set so that when I put the car into a gear, the doors lock, and then when I turn the car off they unlock...... Well they lock when the car is put into gear, BUT they dont always unlock when the car is shut off........... About every 3 or 4 out of 10 times do the locks work right.....
As far as the rear defroster, I have yet to pull the bus panels (think thats what they are called) apart and clean the piece of metal in them and check the wires for corrosion.
Thanks.

If its what some of us are thinking, I'm surprised your fuel pump is still running.

Mine is a 92 SSE and the rear defroster works poorly. After 2-3 minutes, the fuse overloads & "kicks-out" after it cools, the door locks & rear def start to work again. It'* an evil cycle. Could never figure out what'* wrong with the rear def circuit that would overload it.
Also, my 92SSE does not have the auto lock feature.

It might be something you can program as a feature, look in your manual to see if there is anything about it
on my 2000 SE you do cycles of locks/unlocks/key cycles
