06 Silverado Drivers Side Door will Unlock But Not Lock

[SSSilverado23]

I just recently had my drivers side door module go out on me. That switch controls the power locks, windows, mirrors, heated seats etc. I changed it out and now i have a different problem. My power locks will lock and unlock from all doors except the drivers door. It will un lock if i manually put in the lock position but it wont lock.

 

I am at a loss. I went to autozone and bought a door lock actuator and replaced that and i still have the problem. I can here a whine noise coming from the actuator when i hit the lock button. Same noise from both actuators. Any help would be appreciated!

Im stumped right now. I get power to the actuator. Everything works perfectly but it wont lock. I replaced the Actuator and the DDM. I guess a bad connection? Im not sure where to go from here. Ive replaced everything in that door accept the wireing harnesses. I dont know which wire does only the lock? Help is appreciated.....

Even though everything else works? Windows, mirrors, unlock, all of it works. Just not lock.

If equipped with camper mirrors program the door module. Refer to Service Programming System (SPS) in Programming.

 

BTW, I know this one isn't the most up to date for sure.

I'd say you need to visit your friendly GM dealer.
