I had a garage evacuate the system and refill it (~$120) and it has worked well for the 8 days since. Got the Pep Boys circular this week and they are offering a free A/C check. Maybe you want to try that first, if you have one in the area.

Not a problem. I only have 2 kids and they keep my busy enough that I only get to check in here occasionally to see what's new!
 
I see I had a typo in my write-up. I repeated LE, should have been XLE/Ltd has the two servo system. But you probably got the gist of what I meant.
 
Over the past week I popped in a thermometer into the dash vents. I don't get to drive the van much, but I did notice that the left is ever so slightly warmer than the right. Either way, that system rocks - it chucks ice cubes! I saw an outstanding low of 38'F on recirc on a partly cloudy afternoon.
 
Curious... It really didn't sound like you needed to be pumped & refilled, yet it seemed to help. I'm starting to think that the single servo units just must suck in more warm air on the left side, and that is reflected in the outlet temp. Keep us posted on how it goes as we move into high summer.

I have the exact same problem on my 08 sienna, however I need to add one more weird twist. If I put the system on max (recirculate) and turn the rear blower on high, I can get the left side to blow out cold air, most of the time. It works more often if I start from a cool garage or early in the day before the day heats up. This does not work when the system is brining in fresh air from the outside. Although cold, it is still warmer than the left side, The right side always works great in the front and back.
 
Does anyone have a clue how this process allows it to work? Thx krefto

#14 of 16 2008 WITH 70 THOUSAND A/C O-RING by wantodysseybak

Jul 06, 2011 (12:26 pm)

TWO WEEKS AGO, WE TALKED OUR DEALERSHIP DOWN TO 500 DOLLARS TO REPLACE THE
A/C O RING AFTER THE DRIVERS SIDE A/C BLEW ONLY HOT. THEY SAID THE RING HAD A SMALL LEAK. IF IT HAD BEEN ME, I WOULD HAVE RECHARGED IT AND DRIVEN IT UNTIL THE A/C BLEW HOT AGAIN, BUT MY HUSBAND WANTED IT REPAIRED AND I WAS TOO BUSY AT WORK TO DEAL WITH THEM.
 
LESS THAN TWO WEEKS LATER, WE HEAR A LOUD RATTLE WHEN WE RUN THE A/C AT LOW DRIVING SPEEDS. REPAIR SHOP/DEALER SAYS UNRELATED TO PREVIOUS REPAIR. ITS THE COOLING FAN IN THE FRONT THAT HAS A BOLT THAT HAS LOOSENED ITSELF, AND THE FAN IS COMING OFF, HITTING OTHER CAR PARTS. ONLY DOES THIS WHEN A/C IS RUNNING, NOT WHEN FAN IS ON BY ITSELF. I SMELL A MAJOR RIP OFF HERE, BUT NEED MY CAR. IT'S ANOTHER 900 DOLLARS. CALL TOYOTA CUSTOMER SERVICE... THEY COULD CARE LESS. SO MAKING MAJOR EXPENSIVE REPAIRS WAY EARLY IN THE VANS LIFE DESPITE REGULAR MAINTENANCE. I WANT MY HONDA ODYSSEY BACK... HAD 150 THOUS WHEN I HAD FIRST MAJOR WORK ON TRANSMISSION...

I too had the same problem. I had the freon charged and it worked great for 3 months and now it's back to just the one vent (center right) blowing cold. I'd like a definitive answer as to what the problem is as just the labor people are quoting me is in the hundreds of dollars.

#16 of 16 2007 Toyota AC, Transmission, Master Cylinder, Brakes, What hasn't broke? by smbmartini

Nov 27, 2011 (12:06 pm)

I purchased this vehicle in Cleveland Ohio, my first brand new car and I've spent more on repairs than on any of the used cars I have previously owned. So sad, When you purchase a brand new car and pay over $600 per month for 5 years you expect its going to run properly especially when you keep up on service and maintenance. Especially when you think a TOYOTA product is SUPPOSED to last you up to at least 200k miles. Well mine barely made it to 10,000 without costly repairs of some sort. Now at 89k the transmission is deteriorating from the inside, the master cylinder needs replaced and The AC has broken for the 3rd time! The list goes on with repairs needed on this vehicle and at my last 11 months of my loan im completely disgusted paying 617 per month on a vehicle that I cannot even drive! About 4000 miles out of my extended warranty I was informed I need to replace the transmission and master cyclinder. The vehicle was at around 80,000 miles and not even 4 years old. Transmission service or maintenance isn't even a protocol on these vehicle until supposedly 90k-100k, so what gives?? The AC went out on me initially in the middle of 2nd the 3rd year. I lived in FL at the time so obviously it was a priority. Though I had lived in the North from the time I purchased it until 3 months before the AC stopped working. So the AC was never overused and barely used for 2 summer seasons in the North. Initially they couldn't find the leak so I had to pay to fill the freon and the service for AC (the extended warranty would not cover this visit nor refund me) AFTER the 30 days I went back and they found the leak, the warranty covered this minus my $50 deductible. A month before the year anniversary of the repair the AC began the same trouble (blowing hot on the driver side and only working with fan type air not cold, not cool if I turned the rear AC on) The dealership that repaired it would not cover the repair and my warranty had run out! This is all snowballing at me along with the tranny and brake issues. The vehicle has been parked over 6 months and I just cant afford to repair it. I can barely afford the payments. Toyota customer service offered me a $2000 refund if I were t replace the tranny at a Toyota dealer and the cost is over $5000, which I will never have. The refund would supposedly come in 6-8 wks. and they extended this only because of my impeccable service record. Does anyone out there know of any recourse I can take with this? I truly think that Toyota should replace a transmission if it is failing prior to 100k miles and 4 years old. I have poored enough money into this vehicle, brakes, tires, heating elements, AC, windshield washer fluid dispenser, hoses etc. It has been nothing but a disaster and unfortunately cannot fall under Lemon Law because none of the "same" repairs have been needed at least 3xs.
Sincerely,
Extremely dissatisfied Toyota owner will never buy again!
