Hi all,

 

What are the likely candidates for the car failing to control cabin temp? It can do full cool, or full heat and AC works fine.

 

Temperature sensor? Where is it? Easy to test, or a ~£30 suck it and see?

 

Thanks.

There's a temperature sensor in the Climatronic control panel which I think is the main cabin temperature sensor. Each dashboard vent has one too I think.

 

Really you're going to need diagnostics to see if there are any faults reported, and also read out each sensor via measuring blocks. You should also run output tests on each actuator in the system. In both cases you're looking out for odd values/behaviour.
