My 300 locks are not working, I thought the driver door controlled the other doors like if you lock the driver the others do the same and visa versa, also it seems like the driver lock is jammed if you try to push the lock down while the door is open it will not go down. I pulled the panel off to see if i could see anything wrong maybe the unit itself is jammed up or something and should be replaced.
anybody have any ideas?
