A quick and easy (not to mention cheap) way to help those low-buck part-store-style switches is by using this rubber cover. This can be an easy way to protect the switches you have in a Jeep where the switch is exposed to dust and water (such as in the dashboard or in the console). It screws down over the neck of the switch and protects the opening at the lever. If you put it over the mounting nut, it might still be possible for water to seep in behind the panel. While I’ve never had a switch die for that, I have tried to use the rubber-coated nut to retain the switch. It always comes loose.
