2 weeks ago when I had the tie rod recall performed the service writer mentioned that my temperature sensor looked dusty and that it would function more efficiently if it was cleaned. He suggested I use a toothpick to clean the sensor.<p>My choice for cleaning was my shop-vac with an attached .5" straight pipe. I positioned this attachment over the vent and it looked like the end of a Q-tip came out from around the sensor. After 3.5 years of ownership a lot of dust had deposited around the sensor.<p>BTW if you don't know the sensor is behind the 3-slotted opening just above the passenger temperature control. If you look at it and it looks like there is white fuzz on it, maybe it is time for a cleaning.

Re: Cleaning Passenger Compartment Temperature Sensor (dachshund2)

No way would I use a toothpick, but a soft brush, or a shot from a canned air duster wouldn't hurt. The grille collects dust because there's a small fan pulling air through it. You can hear it with the car off, it comes on whenever you open the door.<p>Tom.
