i was able to get a fully functional Techstream copy working on my old Win 7 tablet in just a few mins by following this dudes tutorial. he directs you to a Toyota forum where there are download links for Cisco's little VM player (make sure you get the older ver 5 since it is 32 bit) and an Win XP VM file with a fairly updated fully functional version of Techstream installed. Literally just had to download two different files, install the legit official Cisco player, and point it to the VM file that was downloaded. Then all you need is the USB OBDII cable and a laptop.

But after clearing the AC codes, running the AC diagnostic, and looking over everything it is still having the same issue.

 

I believe the AC Amp can be found near to the glove compartment, which you have to remove to access. Can't say where it is located in your particular car, but that's where it is located in mine .... I have a 2008 Lexus LS 460L

On an American LH drive, the amp is to the left of glove box. Broken gears are a common enough issue with our cars as well. They are part of the servos which may be working since you reset them but cold air isn't being allowed through. You should be able to see them moving once you get the glove box liner out.
