I have a 97 ford escort and the drivers side door is not the same door. So the locks are different

Your door latch assembly may be compromised. It could be rusted, the electric solenoid (if it has one) may be seized. Or the rods from the key are bent. Are you using th key in this door regularly? If not, the tumblers in the lock may be seized. Spray some WD-40 in the lock where the key goes, and jam the key in & out repeatedly, and retry. Remove the door panel & spray the interior of the latch, also. Hope this works for you; or, you are going to need new latches.

Unfortunately, This is a very common problem with Ford Explorers! Ford replaces the locks when it encounters this issue. I managed to unseize my passanger door and tailgate lock, but the drivers door lock is broken beyond repair. You can purchase new remotes for your explorer and program them very easily. Just google ford key fobs...

There are no locks that are operated by vacuum. Whoever told you that the locks are operated electrically was correct. When you are driving the alternator is spinning allowing for more electricity to flo through the vehicle. this could allow more to flow to the lock cylinders.

Aside from the fuses, your drive side power door lock may be failing to work because of a bad door-lock relay system, or, alternatively, the locking switch/button, itself, is not malfunctioning and in need of replacement.

A great handyman site that specifies the above probable causes and more is the following link:
