Product Reviews
Vehicle Fit

This AC heating temperature blend door is a new aftermarket part. It bolts to the blower cover and helps regulate the flow of air into the passenger compartment by opening and closing, like a door in a house. Because it is very active inside your temperature control system, it usually cracks where the air door actuator attaches resulting in a loss of temperature control. So if you are unable to properly control the temperature in your truck or SUV, this may be because this door is cracked or broken!


  • Bolts to the blower cover usually located either under the dash or in the engine compartment
  • Built to strict quality control standards
  • Will need to reuse original mounting hardware
  • Not available separately from the dealer, only available with dealer part numbers: 5134349AA, 5134353AA
  • For models with ATC (Automatic Temperature Controls) ONLY

This AC heating temperature blend door is a great replacement and has substantial cost savings over a blend door assy from the dealer.
