Dial in cabin comfort with the Four Seasons blend door actuator P/N:73735, a direct-fit replacement for the 2004-2008 Acura TL. This small electric motor drives the blend door inside the HVAC case, positioning it to control how much air passes through the heater core versus the evaporator so your temperature setting is what actually reaches the vents. This is the LEFT-side unit — install it in the corresponding position called out for your vehicle.
If a failed actuator is the cause of clicking or knocking behind the dash, air stuck on hot or cold, or a temperature knob that no longer changes the output, replacing this hvac blend door actuator addresses that mechanism.
Complete assembly: includes the lever arm, gear, cam gear hardware, and linkage as applicable.
Internal build: quality internal motor, drive gears, electronics, and connections.
Validated: tested for function, durability, and longevity, and built to match OE fit and function.
Backed by Four Seasons: over 50 years of mobile A/C experience behind the part.
Diagnose the cause of your HVAC complaint before replacing, since these symptoms can have other sources. See the Buyer's Guide tab for engine-level fitment.
