No ac on passenger side only hot air

I have a 2008 tundra crew max and my passenger side only blows hot air
My driver side blows cool and hot and I've check all the actuators and they are working right and all my fuses are good anyone got ideas what could be causing the passenger to be blowing hot air

 

Typically when you see this, the "blend door" actuator or the door itself has failed. In the diagram below (for a sienna, but same concept), this would be the "air mix control servo motor." I would start by looking there.

 

My old Sienna does this too. How bad is it to have repaired?

 

I have replaced those blend door servos on a rx330 and it's not to bad if you are able to access them. 4 screws and a plug, if that is a tundra diagram above they look like the same style as the Lexus ones.

 

Haven't tried it on the tundra, but usually the dash has to come out to access the blower housing/heater core where the blend door is located. Changing out the motor itself should be relatively straightforward, but accessing it is usually a PITA.

 

The diagram was for a sienna since that was the first one I found. I was just trying to show the concept, but I would think the tundra would be similar.

Can you access the Lexus ones under the dash? If so, and if and the tundra is the same, it should be a pretty simple fix.

 

Yeah when I did the rx330 blend motors I was able to access both sides from under the dash, only had to remove the lower dash panels.

 

Any one else had any issues with this? I have a 2014 tundra with dual climate control. I just recently replaced the battery And all of a sudden my dual climate control is at least at 10° difference no matter what. The passenger side blows warm air at about 74° while the driver side is super cold on low. I’ve tried resetting the computer by taking the battery terminals off again with no luck. Tonight I did a self diagnostic on the AC control panel and I get code 21 and 24 for The driver and passenger solar sensors. Also when I Switch to heater the passenger side gets at least 10° hotter. They control doll on the passenger side actually works and controls the temperature it’s just not coming all the way down so I do believe something is out of sync somewhere!
