I have a 2000 Ls1. The heater gets hot and blows, but blows really really lightly. The climate control knob (that directs air to the defrosters, vents, feet, etc.) Turns but does not change the air flow. Also, the button that selects fresh or recycled air does not work.
The other controls on that panel (rear defroster, fan speed, etc.) Work fine.
