What are the problems with a tundra Blender?
Common problems are servo failures, which can be addressed in situ with minimal dash covers removed, blend door failures which require replacement of the heater housing box, and heater core plugging or leaks which also requires removal of the heater housing.
Why is the heat not working on my tundra?
Digging into my own system I found that the passenger heat was not working because the blend door gear driven by the passenger side servo (singular on my SR5 truck without auto climate control) was broken off as the shaft.
Why does my Blend door not turn on?
Since this is just a small electronic part, this won’t be unheard of. If that happens, the blend door won’t work, and it’s likely your temperature will just be stuck on one setting with no ability to adjust the intensity up and down, or alternate between things like the lower vents or the defroster.
Why are the servos on my tundra not working?
The servos for whatever reason get out of time, off a tooth, wire or debris stuck in exposed gears, or just unlubricated over time causing the terrible groaning sounds and confused servo motors. There are some very painfully long videos from “black moses” on youtube explaining the issue but also not really showing you how to fix it.
Where is the bolt on the Tundra truck?

The HVAC system is comprised of a “heater housing” under the dash in front of the center console. This box contains heater core, 4-5 servo motors for various blend doors depending on trim level, and AC evaporator with a wing leading over to the blower motor and AC amplifier above the passenger footwell.
