Turn signals and high beam indicator on dash not working???

The left and right indicator on my dash and the high beam indicator not working, well it does work sometimes but not often. Its a 87 T with digital dash.

Could be corrsion on the back of the dash. I know mine was way nastier than I would have thought when I took it apart to clean up the headlights switch. Made me wonder how any of it worked.

As TexasT says, it's the corrosion, take the cluster out and clean every contact. Also the bulb holders get corroded as well. I used battery terminal cleaner followed up with electrical cleaner.
