Hi...I've recently noticed a clicking sound coming from the dash (more near the passenger side/ behind the glovebox) of my RX300 with 85K miles. The sound is somewhat similar to the clicking sound the CD changer makes when loading . However, the sound is present with the radio off, CD magazine out, and the HVAC system off. It isn't very loud just and doesn't appear to have a pattern. Doesn't matter if the car is moving, standing still, or if the AC/Heater is on or off. Does this have something to do with the HVAC system? Any help will be much appreciated....Thanks,
