94 Auto Door Locks Not

My wife's 1994 Explorer XLT 8-cylinder is starting to get a 
little long in the tooth apparently. It recently clicked over 
the 150K mile when multiple things simply gave up their 
collective ghosts.

First was the fuel pump -- right _after_ I filled the tank. 17 
gallons of premium unleaded down the tube. <sigh>

Then there was the mysterious leak of radiator fluid that 
puddled under the middle of the chassis nightly. The mechanic 
was lucky enough to see the crack in the radiator from the 
return intake. When the engine was warmed up, it allowed the 
crack to open and a few drops would escape (not a massive leak) 
and these would travel like an animator's dream down the frame 
to the middle of the vehicle and exit onto the ground. The 
first guess was her water pump but Lady Luck was with us here.

Then the rear passenger window detached itself from the runner 
guide and we were forced to replace the entire mechanism, 
bushings and all.

Lately another part -- or parts -- have stopped working; the 
auto-locks on two of the five doors (hatchback being one of the 
non-operating offenders.) The driver's door is also no working 
and requires manually setting the lock and using the key to 
open said lock (since the keychain alarm won't unlock it.)

Is there a way of resetting the locks, hopefully purging the 
problem, or might there be some wires that have come loose or 
are the other doors doomed to failure sooner versus later?

Thanks for any ideas.
