And while you've got it all apart, you might as well check all switches to make sure that they click when you press them. And you'll need an ohm meter to check the contact resistance...otherwise you might put it all back together and find out that one or more of the switches still isn't working...
Both of my bonnies have had problems with the rubber pins and the switches themselves. And I didn't find an easy way to remove the circuit boards so I could take them in the house and solder-in the replacement switches; I soldered them while working inside the car instead, so I had to be extra careful.
