Hello everyone I have a question regarding my 06 ZX4 locks. Me rear driver side door will not lock at all. I can not even turn the lock lever by hand. I have removed the door panel and I can hear the motor/or solinoid what ever moves the locking mech. actuate, but I can not figure out how to get to that part to see what is going on with it. The cabel is in place. Has any one else had this problem before, and if so how did you fix it? Also the front passanger side door is sometimes hard to open from the outside. It is frustrating as we just bought this used in December of 2010 with 45000 on it. Any help is greatly appreicated
