    My 2005 Chevrolet Cobalt AC/Heat only works correctly on the highest setting which is 4 on the dial. On 1, 2, and 3 it turns on like it should blow AC/Heat but is not normal more like running the fan only on 1 with no cold or hot air coming from the vents. So only the high setting of 4 works...
