On my 1986 Celica, it was the solder points on the circuit board. You can fix it by removing the heater/ac controller, opening it to access the circuit board and "renewing" the solder points (all of them) by dripping a drop of solder on each point.
Its not that hard. About 1/2 hour to take stuff apart. An hour for the soldering (just a cheap pencil soldering tool). And 1/2 hour to put stuff together again.
If you think you might as well replace your controller with one from a wrecking yard, my experience is that the new one has the same problem. It has to do with the quality of the original solder and the age of the circuit board. It really isn't that hard to do this fix. I rate myself as a below average mechanic and worse electrician and I could do it, so can you.
