My 2011 TC has a very unusual issue. The sliding door on the passenger side will only unlock first thing in the morning, Once I re-lock the doors using my key fob, it will not unlock again until the next morning, or possibly after sitting for 8 or more hours. Any thoughts on this issue? Now my drivers side door is having unlocking issues as well. Not sure if it has the same symptom, it just started today. Is there a site I could find what the voltage or mv is present at the 3 pin connection points on the pillar of the sliding doors when the lock or unlock button on the key fob is pressed? Is there a grounding block for the 3 contact pins on the pillar connecting to the door when closed or are the screws holding the connector to the pillar the actual grounding point? Thanks very much...
