In auto mode, the fan starts slow and builds up. Check the resistor pack, as it is under the hood, and needs good ground.

The compressor should engage immediately when the center button is pushed. Low freon wil either not kick on, or will cycle.

My car is an '82. Did the '81 still use the servo set up?
