No foam tubing.

The sensor sometimes gets fouled with dust etc., vacuum it and you might improve its function.

The sensor functions by air drawn across it via a blower under the rightmost dash vent using a tube from the sensor, across the header, down the right A-pillar, and behind the dash to the blower. If the blower is working properly it will hold a small piece of paper against the opening on the roof (or tissue paper). If the dome-light has been serviced (lamp replacement etc.), it is possible that the clips have been broken and the tube/sensor not properly mounted.

To remove the glovebox liner I suggest removing the latch in addition to the above instructions (to service the blower).
