Question about 1999 Chevrolet Suburban
It doesn't matter if I adjust the knob to the floor, vent or defrost. It keeps blowing all the hot air out the floor vent. Can I manually or bypass the electrical portion to blow the air out the defrost?
Yes those controls are vacuum controlle. Could be as simple as a bad hose or connection.
