Your 4th Gen Ram’s heat or A/C is failing — stuck on one temperature, clicking behind the dash, or not responding at all. Cracked plastic HVAC doors are the #1 cause. This complete rebuild kit from Blend Door USA replaces them with solid aluminum doors. A permanent fix, not a patch.
Fits:
Kit Includes (Dual Zone — 4 pieces):
Single Zone vs. Dual Zone — which do you have?
Single Zone trucks control driver and passenger temperature together from one dial.
Dual Zone allows independent driver/passenger temperature control. Check your HVAC control panel — Dual Zone trucks have separate driver/passenger temperature controls. Note: you cannot convert a Single Zone truck to Dual Zone by swapping doors — the difference is in the HVAC box itself.
Rear Vents: If your truck has rear vents, the only difference is the ductwork — this kit still fits. No additional doors required.
Why replace it?
Solid aluminum construction. Made in Michigan. Lifetime guarantee. Direct fit — no modifications required.
