Tesla Model X Three Way Heater Control Valve Replacement
✔️ Fits 2016-2021 Model X BEV, replaces 1064225-00-B parts.

This single replacement valve regulates cabin temperature by controlling coolant flow into the heater core for early Model X electric crossovers. Mechanics and shop owners use it to fix climate control failures when airflow stays hot after turning off the warmth pump upgrade. The unit swaps directly into the existing plumbing layout to restore crisp cooling during summer trips and quick defrosting during winter commutes.

✅ Compatible with Model X 2016 through 2021 battery electric vehicles
✅ Matches OEM part numbers 106422500B TL422500 and 69799
✅ Resolves issues like stale hot air blowout and weak summer cooling
✅ Manages precise coolant routing to balance interior cabin heat levels

💡 What causes lingering warm airflow inside a Model X EV cabin when the A/C compressor runs normally
A stuck three way heater control valve lets coolant keep flowing past the heater core while the climate computer demands cold air.
- Install the updated replacement actuator to instantly cut coolant circulation and stop hot air drift without tearing apart the dashboard
- Test the vacuum lines and electrical connectors first because worn seals mimic this exact symptom and save you from swapping good parts unnecessarily
- Keep spare grommets and Teflon tape ready since the factory rubber ages quickly under repeated thermal cycling making these swaps pretty handy on weekend garage projects
