The '95 Supra has this:

INDICATOR CHECK
1. Turn the ignition switch on while pressing the air conditioning
control AUTO switch and R/F SW simultaneously.
2. Check that all the indicators light up and go off at 1
second intervals 4 times in succession.
HINT:
• After the indicator check is ended, the diagnostic sensor
check begins automatically.
• Press the OFF switch when cancelling the check mode.
DIAGNOSTIC SENSOR CHECK
1. Perform an indicator check. After the indicator check is
completed, the system enters the diagnostic sensor check
mode automatically.
2. Check the LED blinking on the panel. Refer to the list of codes
on page AC–20 when translating the trouble code from the
LED blinking.
If the slower display is desired, press the RDEF switch and
change it to step operation. Each time the RDEF switch is
pressed, the blinking LED changes by 1 step.

Which leads me to believe Lexus would have something similar...the A/C Manual I have is only like 20 pages long...the Supra A/C manual is about 111 pages long...so I am thinking there might be a better one out there. I am gonna try this method on my SC tomorrow and see if it works.

and what the codes mean:

Wow! Thank you so much! Do you know where I can get access to these FSM-like materials? I have downloaded a bunch off of techinfo.lexus.com but it is still somewhat limited...I know there has to be a CD or something out there that has the in-depth information.

Again, I appreciate your quick reply!

We have a shop manual subscription to Mitchell, as a company we spend about $2000 / month for access to this, maybe more... We also have 14 locations and each location has a 5 user license too... I am sure there are cheaper, easier ways to do it, but I don't know on a personal level...

Yay....code 12 & 21!

I think I have the fix on Code 12 (from a helpful SC guy on this board)...

21 is going to be a different story, gotta figure that one out! Not sure what the deal is with my solar sensor...gonna mess with that a bit.

Car is fixed! Did the Ambient Air temp sensor fix, and swapped to the USDM ECU and everything else is peachy! A/C still isn't super cold, but I still have some bubbles in my system...so I am going to be adding a bit more r134.

Thanks everyone!
