Where is it. Probably under some shroud, but before I start taking things off, can someone point me to where it is from the perspective of standing in front of the grill. Thanks. Can't believe this has not been asked before.

 

I must be the only RX owner that has an air conditioner and attempts to service it. Don't worry. I will find it. Its below the shroud on the passenger side. But that is all I will reveal since no one knows or cares.

 

It's not that we don't care, It's simply we don't know. I searched for the port location in my 2007 service manual with no luck. You are correct almost all Lexus owners do not service the air conditioner.
