Parts for your 2016 Toyota Avensis-Heater tap

2016 Toyota Avensis heater tap — is it even a thing?

Short answer: the 2016 Toyota Avensis (T27 series facelift) doesn’t use a heater tap (also called a heater control valve). Temperature is adjusted by an air‑mix blend door inside the HVAC box while engine coolant flows through the heater core all the time. This isn’t guesswork: Toyota’s Avensis T27 repair manual HVAC section shows an air‑mix damper servo rather than a coolant shut‑off valve
