Hi,

Lately my heat stopped working and barely blows heat on the hottest setting HI. I think it might be the Blend Door actuator, does anyone know where it is located on our car? I want to test it to make sure my 3rd party warranty will cover this. Then i will bring it to lexus.

Found the part its just right behind the dash to the right of the gas pedal, i see all the doors working but with delay. Also while i was playing with the doors, i realized the annoying buzzzzing sound i have had for the past 6 months, its the motor that runs all the doors, it was randomly going off. I pulled two Heater codes for Solar Sensor Circuit for both driver and passenger side. Taking the car tomorrow/sat to drop it of all the dealer for warranty work. Hopefully i get into a new GS350 as a loaner

Solar sensor codes will be there when car is not in direct sunlight.... That is normal for those codes to be present as an FYI

Last year my car was blowing cold air instead of warm. It turned out the coolant level was low... way low. I'd check that before you do anything else.

could be low coolant, clog heater core, or opened thermostat

i have a feeling its low coolant due to water pump.. check it out.
