Air Conditioning problem
1996 Buick Riviera 6 cyl Front Wheel Drive Automatic 89000 miles

The a/c blows cold on the passenger side and warm on the driver side. What causes this?

Either a temperature blend door actuator isnt moving the door enough, or it's low on R134a refrigerant. A tech I scantool is needed to check for trouble codes, GM made no provision on Riv to self diagnose without the tool.
