Parts for your 2002 Toyota Avensis-Heater tap

2002 Toyota Avensis heater tap: is it even fitted?

Short answer: a heater tap isn’t used on the 2002 Toyota Avensis (T22 series). Cabin temperature on these models is controlled by an air‑mix (blend) flap inside the heater box, while hot coolant flows through the heater core all the time. This setup is shown in Toyota’s factory literature and independent manuals.

Technical sources that confirm this include: Toyota Avensis T22 Repair Manual (Heating/Air Conditioning section), which details an “air mix damper control servo motor” for temperature regulation and shows no water valve in the cooling circuit
