My 74 3/4 ton has the heater/defroster slider broke off when I bought it so I can't change the air with out a screwdriver. I found a complete heater control to replace it and was wondering how hard this is. It doesn't look hard just remove the bezel (which I am replacing since mine is broke) and then take the four screws that hold the heater control in out and then disconnect the power wire plug, pull out the light and disconnect the cables, am I missing anything? Thanks!
