Climatic issues

[ChrisBrown]

Hi, my heater is either full hot or full cold. Chnaged the v68 flap control motor but still the same. Now thinking there must be some interior temp sensors which may be faulty. Any idea where they are, how i access and what part they are. Thanks

Wouldn't it be wise to first check measurement values for sensors and flap motors before replacing them? You can check with diag tool
