heat only works sometimes?

Alright, my next project. Yesterday, my heat didn't work and neither did it this morning, however, two days ago, my heat was working fine. Any ideas or where to start?

What doesn't work? The air is cold? The blower doesn't turn on? The panel is blank?

There is a diy on here for replacing the heater control valve if it's blowing cold.

Inspect your heater control valve. It is pulled by a metal line, which opens and closes when adjusting the hot / cold dial on the dashboard.
There must've been corrosive build up or something as my valve eventually got 'unstuck' after awhile.
