Guys... I am also having the same problem here. It started two days ago. Both door will lock with remote control but passager door will not unlock with remote control. I have to use my key to unlock it.
When I am driving, the both doors whould automatically lock itself when I drive above 20mpg but only the passager door will lock not the driver's door.
I tried to press the lock/unlock button at the consol, the passager door would not lock or unlock....... Please helph here.
