Dial in cabin comfort with the Four Seasons HVAC Blend Door Actuator (MPN 73703) — a direct-fit Acura Tl blend door actuator that also installs on the 1999-2003 Acura CL. This motor-driven actuator positions the blend door inside the HVAC case to control how much air is routed across the heater core, managing your temperature and airflow mix.
- Includes: lever arm, gear, cam gear hardware and linkage as applicable.
- Internal build: quality internal motor, drive gears, electronics and connections.
- Tested: checked for function, durability and longevity.
- Fit: meets or exceeds OE specifications for fit and function.
Signs the original may need replacing include a clicking or knocking noise behind the dash, temperature stuck on hot or cold, or inconsistent blending between sides. If a failed blend door actuator is the cause, this FOUR SEASONS blend door actuator replaces it. Diagnose the cause before ordering, since these symptoms can also come from the blend door, wiring, or HVAC control head.
Fits the 1999-2003 Acura CL and 1999-2003 Acura TL. See the Buyer's Guide tab for the full engine-level application details.
