Multifunction switch- Ford?

I have a Ford Taurus, 1995. I pressed the hazard button and those didn't work, and suddenly neither did my turn signals. I brought it to a shop and was told it was the multifunction switch. What I want to know is, is this a common problem with Fords/Ford Taurus. I got charged a huge fee to "diagnose" this at one dealer, when I called another he told me over the phone what the problem likely was. So is the MFS a common problem in Fords?
