Heater Box Interchangeability (Crewmax vs. Double Cab)

I’m hoping to swap a used “heater box” (pictured below) from a 2016 Tundra Double Cab into my 2014 Tundra Crewmax, both with climate control. The two trucks have different part numbers for their entire assemblies including servos, but I’m wondering if the just case with the blend doors is interchangeable between the two? I don’t need the entire assembly and it doesn’t look like Toyota sells just the case.


Can anybody confirm if the box circled in the picture below would interchangeable within part #'s 87050-0C080 and 87050-0C110?

 

@Roman n might be able to help.

 

I can tell you that a crewmax has vents on the rear of the center console while a double cab does not.

If I had to make a bet, I’d say the ducting ports for those vents would be the difference.

 

One of the members said that the center console are the same have the ducting built in to it. I will try to reach out to him and verify that too. I had a different application in mind with mine. Delete cup gold and add vents using cm parts.

 

I wouldn't know unless I had both parts sitting here in front of me to visually see the differences.

 

After conversations with several scrap yards, the answer is no, they are not the same housing for a crewmax and doublecab. Crew max has rear ducts and other cabs do not. Also, limited and higher trims have a different housing from SR5's because of dual climate control.

 

Ok. Thanks!

 

My SR5 has dual climate (pass can set their temp non auto) I'm working on converting to auto and I have a servo that looks like and the wire connector fits the auto servo I bought for the conversion.

FWIW.

 

I think the scrap yards are just covering their ass for fitment reasons to avoid returns. The housings are the same. The only difference between the assemblies is what servos are bolted on and where (dual climate vs single, auto climate vs manual, this is shown by looking at the different fiche diagrams for each trim level), wiring harness to said servos obviously must be different for more servos, and the ducting that's connected to the box to determine DC vs CM. There are no difference in number of blend doors between DC-CM and trim level options, just how they are control and where the air is directed. I would buy whatever 3rd gen box is cheapest and just swap whatever doesn't match over from your existing box.

For example, you should be able to take a platinum CM box with dual auto climate and install all base DC servos/harness/ducting over and have it work just fine. The only flaps in the box are hot/cold, left/right, upper/lower, and if used (CM) front/rear. The cases can be disassembled much further than the fiche assembly part number that's shown as bottom level.
