Blend Door Actuator | 2009-2022 Ram 1500 2500 3500 | OEM Mopar 68448026AA

Your heat is stuck on one temperature — or the A/C won’t respond no matter what you set. On 4th Gen Ram trucks, a failed blend door actuator is the most common cause. This is the OEM Mopar replacement, direct factory spec.

Part Number: 68448026AA

Fits:

• 2009–2022 Ram 1500 (Single Zone & Dual Zone)
• 2010–2018 Ram 2500 & 3500 (Single Zone & Dual Zone)

How many do you need?

• Single Zone cab: 4 actuators total (4× 68448026AA) to fully rebuild the HVAC box
• Dual Zone cab: 5 actuators total (5× 68448026AA) to fully rebuild the HVAC box
• Rear vents: no extra actuators needed — rear vents are additional ductwork only, not actuator-driven

Single Zone vs. Dual Zone — which do you have?
Single Zone trucks control driver and passenger temperature together. Dual Zone allows independent driver/passenger temperature control. Check your HVAC control panel — Dual Zone trucks have separate driver/passenger temperature controls.

Why replace it?

• Heat or A/C stuck at one temperature regardless of dial position
• Clicking or ticking noise from behind the dash
• Temperature control unresponsive or intermittent
• One side of the cab heating or cooling differently than the other (Dual Zone)
