jlaguard Posted October 3, 2006 Share Posted October 3, 2006 I have a 2001 RX300 with >100K Mileage. Recently my heater has stopped functioning. The AC works at all temperature levels from min-max and the fan output seems normal. At the time it stopped functioning I remember smelling a slight burnt smell and actually a plume of smoke came from the vents. Please note the seat warmers still heat up. I took it into two different Lexus Dealers who both said I needed to replace my servo motor. Does this add up? I was thinking maybe it was a bad thermostat or bad heating coil but I don't know much about cars to make that statement with any degree of certainty.
