jlaguard Posted October 3, 2006 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.
Booyah Posted October 3, 2006 Posted October 3, 2006 If your temp guage reads normal then its not the thermostat. Sounds like the dealer is right, seems your valve is not switching over to allow hot water into the lines.

The dealer said it would cost 1100 to fix the motor

The dealer said it would cost 1100 to fix the motor There is no hot water shut-off valve in the 2001 RX. Assuming that you cannot moderate the cooling level except via blower speed or turning the A/C compressor off your problem is most likely the mixing vane/door servomotor that apportions cooled airflow through the water heater core. I'm pretty sure the mixing vane servomotor is accessible without disassembling anything. Passenger seatback fully reclined, upside-down with head into passenger footwell but.... Assuming it is the servomotor itself.
Booyah Posted October 4, 2006 Posted October 4, 2006 Thats what I meant but did not no all the details:) I was right in a way $1100 seems pricy to me, but not sure what all the parts--How much time are they taking for labor?
jlaguard Posted October 9, 2006 Author Posted October 9, 2006 Do you feel that's a reasonable price from the dealer?
