From an earlier post by a member on the subject. Seems to work the best..
Get some CRC electrical cleaner and spray the heck out of them on the inside, and then work the buttons. Or radio shack or Napa carry electrical cleaner. Once sprayed work the buttons in and out a bunch and should free them up. If you have shop air you can chase the cleaner with it. I pushed my hazard button on my 95 yesterday and it stuck in, sprayed with cleaner and works fine now.
