The air switch used in jetted tubs is mounted in the box on the bath pump.
Remove the pump from under the tub and take the top of the little box off by removing the two screws holding it in place.
Once the screws are removed you may lift the lid off and you will see two wires going to the air switch, one wire coming from the pump power cord and the other from inside the motor.
Remove the two wires from the air switch and then remove the air switch from the pump by taking off the nut that holds the air switch in place.
Reinstall the air switch by putting the two wires back onto the air switch and put the cover back on the box on the motor.
