I have a problem with locking and unlocking of the drivers side doors.

When I use the key fob the passenger side locks and the two doors on the driver side stay unlocked.
I have replaced the battery in the key fob but the drivers side locks still continue to not lock. Any help would be appreciated. Thank you!

 

Hello and welcome to the forum! It sounds like there may be an issue with the locking mechanism/actuator. If this does end up being the problem, take a look at the link below to a DIY replacement guide. Hope this helps you a bit and best of luck!
