Have you tried using electrical contact cleaner on the switch itself?
I had another car that this problem happened to after a large McDonalds sweet tea was spilled into the console... Long story.
Anyway, I pulled the whole switch panel out and used electrical contact cleaner on the switches from the back and they worked fine after that.
