First, check to make sure the connector is tight. the contacts inside the switch are probably dirty or just plain worn out, WD40 will probably not fix it, you'll need to take the switch apart, and carfully clean the contacts inside with a small wire brush.
from what I can see (my car has manual mirrors) you'll have to pull the center console apart, start at the shifter surround (screws are under the ashtrays), iirc, one the surround is removed, you should then have access to the screws holding the switch in place.
