I'm a 2006 TSX owner but I'm posting this for my coworker he has a 2008 TSX he took it to a dealer they added some freon and the additive to check for leaks none was found. The problem he's expierancing is when the engine is revving / moving the AC is cold but when the car is idling the AC is blowing warm. Dealer couldn't find anything wrong just a side note it was a Nisson dealer.
Any ideas what could be the issue causing this?

He needs to check system pressures at idle to see if low cooling is caused by AC system or perhaps a heater blend door issue. Suggest trying AC in manual mode to see if any difference.

A weak compressor, dead cooling fan (there are 2), or dirty condenser might also cause low cooling at idle.

good luck
