I have a 1996 Nissan Maxima. It was about 95 degrees today (measured with my own thermometer not what the weather report says), and my air conditioner outlet temperature was reading about 50 degrees. that would be temperature differential of about 45 degrees. I had the fan on second lowest out of 4 settings and on recirculation.
<br/> Does that seem reasonable?
<br/> I had the car for about 4 years now, and the air conditinoner had been all right when I first bought it, but it has been progressively getting warmer. Today, when the outside temperature was registering 95, the car interior would not get cooler than 80. Even when I drove for 20 minutes on the freeway.
<br/> Is there an easy way to check whether the air conditioner is working properly?
