My 2003 Saab 95 sometimes blows warm air from the passanger side and other times very cold airwhen the ac in the auto position... I am guessing but I think it is somehow related to the thermostat on the passanger side. Prior to noticing this I would occasionally hear a click click click sometimes when strating the car and sometimes when turning off the heat. Is there a relay or a simple fix for this? Thanks,
Greg
