Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

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.

My 98 Buick Century was doing the same thing. Up here is the north we have Canadian Tire. Went in there picked up a aircon recharge kit called RED TEC 12A hole kit costs $40 cnd I put 1 can in on the low pressure side which is the only fitting that the filler would fit on and now I have 33 degree air coming out of the drivers side and a couple degrees colder from passenger side.
I am sure you guys have something like Canadian tire down there you might even try Wallmart.

SOURCE: a/c blows hot air on drivers sde
The actuator door on the driver's side is out of position and needs to be reset. Remove the negative battery cable for 1/2 hour to reset the computer. Start the HVAC system and you should be able to hear the door adjusting itself and cold should come out of the driver's side vent.
