I have read similar posts, but can't seem to solve my issue. Had our van in yesterday for new rear rotars and pads. When my wife went to pick it up, the key fob would not unlock the doors, nor would the lock/unlock buttons inside. She had to use her key to enter. Noticed the following doesn't work: temp gauge, blinkers (but hazards lights work) sliding doors will not open, no high beams. I have removed the panel that covers the spare tire and removed the spare tire to better get at the wiring harness. I used a high dryer to hopefully dry out the connection, but it still does not work. Am I looking at the right connector? Its the only one I see?
