when I brought my car to florida the humidity played heck with the fuses. I took all of them out and wire brushed the terminals in the box and replaced them with new ones from MB. used a lot of dielectric grease too. this fixed a lot of intermittant and bothersome issues with one pass, including the passenger front driver rear window issues I was having

also, if you recently replaced or removed your window switches, it is wery easy to get them connected wrong. The plugs will go on in many different combinations resulting in some windows not working or blown fuses....
