Has anyone tried collecting on the air conditioning TSB?

I have copies of many of them, but only those that may apply to my box... I'll dig around and see if I still have a working link to the Scion TSBs somewhere... May be awhile, though, assuming I find it.

Sensez, give this link a try:
Scion TSB copies
There's NO guarantee the link will live forever, so grab the ones you may need and hold on to them...
Hope that helps.

where do you find info on all these TSBs?

i'll try to sum it up short:
my xb is said to have a rodent in the ac system, said by the toyota serv. dept techs, all chopped up by the fan.
they told me to do to fix the problem it would cost me 1200+

Find a different mechanic.
The TSB is a different issue. I think that getting it done is a matter of luck and perseverence. Be familiar with the test procedure (described earlier in this thread) before discussing it with the service writer or technician. It's not just sticking a thermometer into the outlet and reading a number!
You might get lucky and have them perform the TSB without a fight, but it seems like some dealers actively discourage customers from getting their TSBs satisfied.
I wonder if Toyota is shorting the dealers on the hours to perform the TSBs?

I didn't have to mention TSB or fight with the dealer over getting mine fixed. One day, out of the blue, the a/c was blowing warm air...took it in, and the dealer replaced the compressor. Problem solved.

The TSB addresses a weak AC system, and the sticking point is that Toyota's functional test is rather complicated to perform. I've yet to hear of any tech determining the relative humidity, which is the first step of Toyota's test procedure. Even the weak early Scion AC systems will make nice cold air at low blower speeds and cool outside air temperatures! Change the test conditions to the ones that Toyota specifies and I'll bet that few early Scions will be within spec.
Did they also replace the evaporator per the TSB, or did they just replace the compressor?

However, according to Toyota's chart of acceptable temperature differences, lower humidity should produce a greater difference in temperature.
At 30% humidity, Toyota's specification says that the temperature difference should be 19.5C to 25.5C (35.1F to 45.9F)
This would mean that the outlet temperature should have been between 37.1F and 47.9F. The value I actually measured (51F) was above this range. Even worse, the lower humidity should have yielded slightly lower temperatures. Extrapolating the maximum and minimum curves of Toyota's acceptable temperature graph to 20% humidity yields an acceptable outlet temperature range of 34.4F to 44.3F. The measured temperature value is 6.7F above this range. a significant difference.
I'm hoping that tomorrow I'll get temperature and humidity within Toyota's test values. The problem in my part of SoCal, is that by the time the temperature is in Toyota's test range, the humidity goes too low!

I took the temps in Celsius, as this is what Toyota uses and it is a pain converting everything to Farenheit.
Again, this is with everything set per the Toyota procedure: Car stationary, in shade, driver's door open, engine at operating temperature at 2000RPM, blower on high, outlets set to face only, AC on, temperatures stabilized and measured at inlet and outlet by digital thermometers. Humidity was measured by a Davis electronic weather sensor.
Inlet temperature: 30.0C
Outlet Temperature: 13.2C
Outside Relative Humidity: 27%
Temperature difference: 16.8C
Toyota's specified temperature difference: 20C to 25C at 30% relative humidity.
Clearly, my xB cools air, but it doesn't meet spec.

Last year I noticed the a/c was a little weak, but I tend not to use it much so I just ignored it. This year with the 2 weeks of 90+ weather and humdity the a/c was so weak that I had to blast it on max to get any results and finally had to give it up when I got stuck in traffic as it just wouldn't keep up.
I found this thread, looked at the TSB AC007-04 and found my VIN falls under the
Air Conditioner Accessory Assembly and Air Conditioner Additional Kit section.
I went outside and put a thermometer to the a/c vents. The temp outside when I tested was about 65 degrees. After 5 min at full blast the temp was only blowing at 49 degrees. So I can imagine what it would blow if the outside temp was 90.
The car goes in the shop on Monday for an evaluation. I'll post the results.

At the risk of sounding like a total idiot, I discovered that in the tC having recirculation on makes a much bigger difference than it does in the xB. I knew that in the xB having recirc on helped but not that much, so I wasn't using it in the tC. One day I was stuck behind a garbage truck or something so I turned the recirc on to keep the smell out. I forgot about it and left it on and noticed that the A/C was blowing impressively colder.
So just maybe it can handle 115 F after all. It is not having much trouble with 95F with recirc on.

the fuji is ____ed.
i left it a dealer with INSTRUCTIONS on the TSB . they called back and said they found nothing. im ____ed its hot and humid and the TSB was not fixed. i called scion before i left it at the dealer and they confirmed my VIN was for the ac TSB. but the delear said that to go back if i wanted. ( such BS ) on monday im calling scion and complain..last week i was out on business and did not need the xb for nothing. so now i do and imma suffer the bad weather.

Well I took my car to the dealer today for the a/c problem. I noted that my vin falls within the TSB vin range. Without a problem they ordered the parts and will call me when they come in. Great service!
