Those are similar to mine, take the assembly out and check the connectors from the assembly. They are spring loaded and you may have to use a small screwdriver and pull them out so that they can make the proper connections. For some reason through time and shipping they get flattened and do not make a good connection.
Keep the same tools to remove the assembly in your car incase you have to do that on the road, I had to do that repair at 11PM in the middle of nowhere Texas last trip.
