Drivers Rear door, no power lock or window

On my 94 Le Sabre, all of the power door locks work except the drivers side rear door. Any ideas on where to look to fix this problem? When you hit the unlock button all the doors unlock except that one and the window will not go down when you use the master switch (drivers)

Thanks

When you have more than one failure of things on a car I would look at what common item powers them. I'm thinking the commom thing would be the ground. Try taking a long wire and hook one end up to a good know ground. Find a place on the door that will make contact (around the latch) and touch the wire to the door. Try the window and lock. This is just a hunch.

On the other hand, you could just have a bad window motor and a bad locking mechanism.

Get the tool to lift out the plastic darts that hold the door pannel on and take the pannel off. Look for broken wires where they flex.
