Hi i have 2012 all4 need some advise on how to diagnose central lock issue ,

if i use the remote it will lock ( driver side only ) but not unlock any door

if i use the switch toggle inside the car it will only lock the driversdie door , but wont unlock any door

So what could be the problem ? Is this a problem whith the whole central lock or is this just a problem with the driverside actuator ? I wanna make sure i diagnose this right before buying the part

thanks in advance for anyone that can help !!

 

Thanks again for this forum, found the solution on another thread. it was the fuse !! But i guess one of the actuator ( passenger rear) is defective since its not responding to the fob or toggle.
