AC only cools on LO setting
BradFerg replied to BradFerg's topic in 04 - 09 Lexus RX330 / RX350 / RX400h
Problem resolved. A sensor had not been re-connected after replacing the evaporator. This sensor uses the ambient temperature in the car to make adjustments to A/C and heating. Without the sensor, the only A/C setting that worked was LO since this by-passes and/or does need the ambient temperature in the car. -

2008 RX350; AC cools with the temperature set to LO. Raising the temperature setting 1 degree above LO and you only get hot air. What would cause this. Have basically lost control of the cooling temperature.
