heat/cooling issues

My 78 blows air temperature air no matter what the temperature switch is set at. Blows hot air in the summer, and cold air in the winter, no matter what. What could possibly be wrong with it and what would it take to fix it so it functions properly? Since Im going to be driving my truck all summer, I dont want it to blow hot air when its not even set on hot. Also, I do not have air conditioning if that helps.

Lastly, in a previous thread, I heard that the only way the fan can be shut all the way off is by cutting one of the wires to the fan speed switch, which wire is the one that goes to the lowest power on a 3 speed switch?
