well before hand lets just say that this should only be attempted by a professional because when dealing with anything electrical very is defiantly some danger when doing anything like this yourself. First you need to remove all refingent from system.then remove the switch. last replace switch and refingent. that is a oversimplification but you get the idea.

This job should be done by a qualified refrigerant recovery A/C mechanic. Remove all refrigerant from system, remove switch with wrench, replace with new switch, replace refrigerant.

Anytime you need advice for making a car repair you should know the make, model and year of your vehicle. This will help determine what parts you need and how the engine is designed. After you gather this information you can often purchase books about your specific vehicle and how to make repairs on your car.
