Passenger Compartment Temperature Sensor

[RexW]

I have a 1994 LS 400 and the climate control does not work properly. I have to manually adjust the on/off to regulate the heat or cool. I have heard that there is a passenger compartment sensor that either is plugged or needs to be replaced.

Can anyone tell me where this sensor is located?

Thanks

I only know of the one by the driver's knee

1 return temp sensor that needs to be cleaned by the drivers right knee.

The rest monitor the vent temps with a sensor in the vents.
