Same cracked plastic, same failed doors — but your Mega Cab has rear vents, and that changes the kit. This is the complete Blend Door USA rebuild kit for 3rd Gen Ram trucks equipped with the rear vent system, Single Zone configuration. All five HVAC doors replaced with solid aluminum. Permanent fix.
Kit Includes:
- Solid aluminum Recirculation Door
- 2x Solid aluminum Blend Doors
- Solid aluminum Panel/Floor Door
- Solid aluminum Defroster Door (rear-vent specific driver)
- Extra linkage rod + aluminum cam gear for rear vent control door
⚠️ The original plastic rear vent control door is re-used. It is not directly driven by an actuator and does not seal against any surface — failure rate is extremely low and replacement is not warranted.
Fits (Single Zone, with Rear Vents):
- 2002–2008 Dodge Ram 1500 Mega Cab
- 2003–2009 Dodge Ram 2500, 3500, 4500, 5500 Mega Cab
- 2007–2009 Sterling Bullet
⚠️ Rear vent fitment note: This kit is only for Mega Cab trucks with the rear vent system — the vents located at the bottom rear of the center console or jump seat. Single Cab and Quad Cab trucks do not have rear vents. Not all Mega Cabs have this option. If you don’t have rear vents, order the standard Single Zone kit instead.
Single Zone vs. Dual Zone — which do you have?
Single Zone trucks control driver and passenger temperature together.
Dual Zone allows independent control. You cannot upgrade from Single to Dual Zone by swapping doors — the HVAC box is different.
Why replace it?
- Heat or A/C stuck at one setting
- Clicking or grinding from behind the dash
- Airflow mode not switching (floor, dash, defrost)
- Previous plastic repair that failed again
Solid aluminum. Made in Michigan. Lifetime guarantee. Direct fit — no modifications required.
