Air Conditioning Amplifier

[howsyourself]

Hi all,

I had an issue with my 2013 is300h causing my air con to delay start while running some diagnostics in the background when I try to turn on the vehicle.

This wasn’t the end of the world and was happy to live with it but then the cold air became warm. I was told the Gad needed to be recharged and so I brought it to have this done in a local auto air con specialist. 
 

He was happy to tell me it was holding Gad but there seemed to be another issue and they continued to diagnose for an hour and half. Then he came to me saying that they found the issue, the air conditioning amplifier.

I got a replacement part and brought it back to the him. They then fitted it and explained it still didn’t resolve the issue and that they would need the vehicle for 24 hours. It now has a new error when started: ‘Check Grille Shutter System’

 

This error keeps popping up after you clear it, so it is pretty annoying.

So, I have the replacement amplifier fitted and I would like to try the old one, just to see if it will get me back to the original issue, of just the diagnostics check and not the ‘Check Grille Shutter System’ 

I am finding it really hard to be without the car for a day as I have school runs to drop/collect three kids.

Does anyone know the location inside the car of the Air Conditioning Amplifier, so that I can swap back to the original part?

many thanks in advance

There's a repair manual here. Perhaps you could find it in there. http://zatonevkredit(blocked word)/repair_manuals/viewdoc_html/AWHuj7EURvZszzJrV4Yg?utm_source=LexusOwnersClubUK&utm_medium=ForumLinks
