Just purchased used. There is a sticker under the hood that reads " Rear AC disabled. Charge Accordingly". Have you ever seen this sticker? how can we fix?
I have had 1 van where it had rear air with controls in back also. I had work done on it several times. There was a fan for the rear air on my van on the drivers side before the driver side rear tire. the fan may be the noise you hear. As far as the charge goes It took more Freon to fill up the system because the lines ran to the back of the van. It cost more because of the extra Freon also. When it says charge accordingly I think they are saying that this van will not hold as much Freon because the back system has been disabled(may have capped or plugged the lines to the back.. One more thing the A/C compressor cost about twice as much as a regular one because of the size of the system.
SOURCE: AC Wont charge after replacing components
whenever the ac system has been opened it should be hooked up to a vacuum pump designed to evacuate the ac system of any foreign debris and oil etc and after should be able to hold a vacuum to show that there are in fact no leaks then if all is ok at this point you can then charge your ac with the proper freon specified for you car when the pressure reaches satisfactory level the ac compressor will then cycle on you should not bypass the low pressure switch

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 1999 limited does this. When i bought it off the guy he said that its because of some flap down by the passengers left foot. In mine the passenger air barely even blows because of this.

You will need to recharge your system , go to the nearest parts store and buy what ever brand that is recomended, and attach it to the lower air conditioning recharge valve.
It's most likely a vacuum line, look
under your hood (close to the cowl panel) for a disconnected, cracked
or broken vacuum line.
In some rear cases, it could be the
vacuum switch (in dash). Or vacuum diaphragm (under dash).
Hope this helps you ???
