1998 s90 automatic trans. 120,000 miles. When I start out the air conditioning is working fine. After the initial cooling the system still is on, fan blowing, but the temperature stops working, and the air becomes warm. The happens most frequently when driving around town. If I get on the highway, and am driving at higher speeds, the system appears to work as it should. The problem gets worse the hotter it is.
