Hello,
I just bought a used but very nice 06 GS300 . The problem I have is the AC is blowing warm air. I checked the cabin filter (it's clean), the compressor clutch (it's engaging) and the inlet vents under the wiper blades (clean).
I would like to now add more refrigerant but can't seem to find the LOW Side port. I know the HIGH Side port is in front of the radiator on the right side. I spent a lot time searching the forum but can't seem to find the answer. Is it the port at the LEFT side rear of the engine next to the battery?

Thank you for your help!

I am not answering your question directly because I do not know the answer, I just wanted to suggest checking the engine coolant level while you are at it. Warm A/C can be a sign of low engine coolant.

Trace the lines from the compressor youll find it.

Thank you for your help.
The LOW side port is located directly below the brake cylinder on the right driver side rear of the engine compartment.

When the clutch is engaged, that should mean you have freon in the system. If you are get no coldness then I would suspect the compressor is bad internally or blockage in the lines.

Lately my 07GS350 doesn't blow cold air when the temperature outside is 85F or hotter.
Just cool air. Not cold enough to cool down the interior.
Probably time to have the AC recharged. Car is almost 7 yrs old.

You can have the ac vacuum and replace the dryer. Its like a filter for the ac system. Also check your condensor if there isnt anything blocking it or mud caked on it

The car is still under EW for a few more months. I am going to have the AC system checked.
It probably needs a recharge.
