The driver's side door will not lock or unlock via remote control. What is the solution for this? All other doors lock/unlock when remote is used.

Is it freezing there? (ice happens)
car drives perfectly day and night? (tells me battery not dead or weak)

does outside metal key work, does inside lock lever work?
if not its frozen inside.
ill assume the 2 mech, ways work and solenoid is dead.
get car serviced?
do you have tools, and skills?
yes/no?

this, its a solenoid. seen below. inside the door.

The FOB battery weak can cause this, try both fobs yet.
one door RKE receiver (hidden below) can be weaker or stronger.
and may fail if the RKE (fob) is weak. Rem.key entry=RKE
so a new battery in the fob is a now thing.
22year old FBO battery? hopeless if ever.
ok if the manual doors work ok and only a good fob fails (both)
(car came with 2 so...)
then the problems is below.
here is an example of how complex it can be. and real solutions.
93-97 location. reciever.
Just pry up the defroster grille panel and it will be on the passenger side, held in by 2 screws.
scan the PCM first. looking for RKE errors, BCM errors>?
if 12vdc does not reach the solenoid,
then the Door controller failed or the BCm fail to sen the command or the remote receiver (entry) module never sent it.
my guess is the RER is ok, as it opened other doors.
so that leaves, BCM mess up. or soldenoid bad.



here is the receiver. that is failing, if 2 fresh fobs fail.
fresh batteries.
some green PCB below are in overhead lamp module
others are in door, (sun roof?)

i think this is 1999.


this found on some 97s. RER
