Nissan Pathfinder A/C..not cool enough!!

[srigith]

i have got this pathfinder ( 2006 model)..the vehicle is good..but the A/C ..i m not really satisfied with the airconditioner. Its jus not cool enough..if i m out in the peak afternoons i m virtually sweating, so u can very well imagine the plight of ppl in the back seat!! If u touch the A/C vent it is cool..but the vehicle doesnt cool!!..On a long drive i feel the A/C are slightly better in performance....I have gone to the service tech and they cant point anything specific..Pls advice..

The FSM has graphs of center vent temperature vs outside ambient and humidity after 15 minutes of activation at a certain rpm in the total shade.

Best to measure center vent temperature after 15 minutes at 60 mph staedy cruise..............be sure to data log start vent temp at 1 minute after cranking.
