I just replaced all the cables in my 64 C10 (lovingly known as "Ugly Truck") after I'd rebuilt the heater control. Seems the cables were junk and wouldn't free up even with the new control arms.

Scott's given you good directions for removing the control. You may have a brace at the bottom and you may have to loosen one screw in the instrument panel bezel.

I'd strongly suggest replacing the cables at the same time as you rebuild the control. You'll thank yourself if you do and (if you're like me) curse yourself if you don't.

I just took my truck on a trip from Utah to Colorado and back and used the controls more during that rip than I have since I've owned it. It was REAL nice to have them working well.

One other thing I did was to replace the blower motor (the old one was sorta balky) and taped up the defroster vent hoses. They were a little leaky. Now that sucker blows thru the defroster like there's no tomorrow.

If I could only keep the motor warm. I'm gonna have to put a redneck thermostat in it for the winter (cardboard in front of the radiator) cuz the 292 runs so cool...and that's without a fan! (It does get hot if it sits and idles for an extended period of time.)
