Iwas told if you have a bad solenoid on one of the doors usually the one that wont lock or unlock is what the problem is . i have a 03 t/c ireplaced both of the sliding door solenoids and it still likes to keep locking . it has burnt the new ones up till they stay in the locked postion i replaced both of them again and left them unplugged so i could open the doors . i just manually lock them a chrysler tech said to hold the door lock switch up for 10 seconds and it resets them for awhile i always wonder if the wiring tracks in the slides were causing the problem ,
