Hey everyone! I am having some trouble with my driver-side door lock mechanism. The door will lock/unlock just fine, but when you use the key in the driver's side, it will not trigger any of the other door locks nor will it roll up the windows. If you use the trunk or the passenger side, all the doors lock just fine. I noticed this after I got stuck driving through Houston during one of the many floods. Anyone have this happen to them? Any tips on where to start looking? Obvious choices are the lock itself and the control computer under the back seat, but is there anyplace else I should look, or perhaps a fuse I should know about? Thanks!

Recently had the same EXACT problem. You need to take off the door panel and make sure the plug to the door lock actuator is connected and pushed in all the way. Also, might as well check to see that the vacuum line is in also.

Since I had just replaced the actuator months earlier, I knew it was not bad. If plugs look good, possible bad actuator.
