That's weird - the manual says this - "The feature uses a rain sensor that is in the area around the interior mirror." And - "Keep the outside of the windshield clean. The rain sensor is very sensitive and the wipers may operate if dirt, mist or insects hit the windshield." When I look at the windshield in that black box area near the rear view mirror, there is a flat black disc stuck to the windshield, as well as a camera lens looking thing facing directly forward. Does the service manual show specifically what each of these are? I assumed the flat disc was the rain sensor.
Are you sure on that? With the Sunpass you pay the same regardless as long as you have your plate registered with your account. The administrative fee only applies if you have to pay the invoice they send by mail. If you have money in the account (mine auto replenishes at $10) and the plate registered, you should never get a mailed invoice.
"Customers who choose not to participate in the NC Quick Pass program will pay their tolls through Bill by Mail. As a vehicle passes through a toll zone, an image of the license plate is taken from an overhead camera. The registered owner of the vehicle is identified through the Department of Motor Vehicles and a Bill by Mail is sent to the customer for payment. Bill by Mail customers will not receive the discounted toll rate that NC Quick Pass customers receive."
I'm fairly confident the camera lens is the rain sensor. The light level sensor is on the dash for headlights, interior dimming and such.
I guess I better look at the FSM a little closer or pay attention to premium cars on dealer lots. Sorry about that. :doh:
