Air Conditioning problem
1997 Nissan Maxima 6 cyl Two Wheel Drive Automatic 161000 miles
My air conditioning only seems to work when travelling at freeway speeds. No matter how long I drive in the city, it does not cool down the car. To try to solve the problem a year ago, I had the air conditioner serviced at the dealer, which I think involved cleaning it and charging the freon. They did not find anything else wrong with it.
Is there some specific problem that would cause the ac only to work when travelling at freeway speeds.
