Climate control System

[Damian.I]

Hi,

I have an 00 Toyota Allex (corolla), it has the digital climate control panel.
Is anyone able to point me in the direction of schematics for this. What I am trying to work out, is if there is a temp sensor(location) for when the system is in Auto and manual.

My current fault is that the system will only go full hot or full cold. It stay full cold until the temperature is set to about 28 degrees, then it goes to full hot.
Nothing in between. This is regardless of how long the car has been running, or what the temperature is outside. As I can get full hot by selecting a very high temp, I have ruled out the coolant system/ heat exchanger.

Any suggestion of possible cause, or info on the whole system would be greatly appreciated.

 

Cheers
