Question about Toyota Cars & Trucks
This model seems to have a number of different air con units, front driver, front passenger, rear air con, console cold box. Drivers side blows cold but cuts in and out, passenger side just blows hot, console cold box ok and rear air con ok. Is there a separate compressor for the passenger air con that could be causing the problem if so where is it located and what should I do.

There is only one A/C system split into 2 zones. Check the blend door actuator, it may have failed in one position or something may be jamming it. Also check the control panel in the dash, My 98 yukon did the same thing, no matter what temp you selected for the front it would blow at about 70 degrees. There is a circuit board in the control panel that gets corroded and one of the circuits controls blend door operations. Have a look.

i was a GM mechanic for many years, the problem you are having is one of your mode door actuators has gone bad, most of the time it is the actuator on the drivers side that causes the problems, i have seen this many times, sometimes you can take it to the dealer and they can hook the computer up to it and recalibrate it but most times it has to be replaced , it is located under the dash in the area above your gas pedal.

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.

It sounds like your electronic vent actuator has gone bad, it's common to go bad and may need to be replaced. There are tinny gears that wear out and the vent actuator stops working. You can try this, turn the radio off first so you don't have to enter the reset code to activate your radio. Disconnect the battery for 30 seconds and reconnect it, if the actuator has lost it's base line and stuck in the open heat position, this will reset it, just make sure the setting is to cold and off before disconnecting and reconnecting the battery. If this does not work, then it's a bad actuator and Auto Zone should have the part you need and will have the step by step instructions for you to the job you self, I believe the dealer is a $415,00 repair cost for this. Good luck and keep me posted.
