I had same problem on 2000 Lesabre blowing cold on passenger and warm on driver. I fixed it by adding more freon even though it had 28 pounds of preasure. Now it works great!

there are two a/c lines that run down the fire wall under the van to the rear.right around the bottom of the fire wall the is a connection point on both lines. you will find a leak there .replace the orings and recharge system. also you will need two specail toyota tools to release the couplings.i have done this repair on several sienna's. let me know if this helps.

Yes there is both a door and a flapper you have a problem with a blend door motor, it is not switching to cold it is half open and half closed so you need to replace the motor vacuum motor it is under the dash near the heater on the passenger side and if it is the other motor under dash you will have to take part of the dash apart to get to it, to test buy a piece of vacuum hose 1/8 inch diameter about 3 feet long and you can hook it to each of the vacuum motors and **** on the end of the line to see which one is causing you the problem, also could be the control head for the AC inside the car where the controls are, you have to remove the ac cluster ot get to the vacuum switch it's all vacuum operated and if you pull it out you will be able to here an audible sound of air leaking if it's the switch.

You have to find the motor that controls the blend door and open it manually to find out which one is bad there are 3 blend doors on the HV/AC system one will be where the heater core is. The other will be between the vented air and AC? heating system then the third door will operate vents in dash and defrost condition. If you have someone operate them AC system heating system and watch the blend door motors, the one you find not moving will be the one that has the problem. They have vacuum and electrical motors, if it is a acuum motor you can move the door manually with your hand, if it's electric you will have to disconnect the rod by removing the pinch clip off of the rod.
