a/c problem


Recommended Posts

hello to everyone, last post was a few weeks back. i went on a 10 day trip with the family to delaware (nascar race) & virgina (family attractions). this was the first long trip with the 97sts. the car ran great (23mpg) but i did notice that the a/c did not perform well in traffic conditions (94+degree heat) once out of traffic the a/c was fine. any help would be appreaciated. thanks in advance jm.

Have you verified that the cooling fans are operating properly when the A/C is on? That would be the first step. High and low side pressure readings would be helpful.
