i have a 72 c10 and i need help with my defrost and heater controls.. can anyone show me a picture of what i need to do and what it looks like under the dash? I think im going to order the heater control box w/o ac out of lmc along with the cable set but does anyone know if thats all i need? i have the heater box so i wont need that and i saw but other than that i dont have anything else. can someone help me out.. this is one of the last things i need to do to finish my truck!!

I just replaced the control on my '68, it's stupid simple. All that's involved is the control panel itself, the snap-in light and the cables. Does the LMC kit included the electrical components for the fan control?

yes i believe so i think in the catalog its #22-heater switch

I just finished refubing my interior heater components - just take it one step at a time...

1st remove and check control unit operation and fix or replace as necessary. I repaired mine to as good as new.

Remove and check the cables. Mine were very hard to move. Working fine now after lots of lubing.

Then I took out the main heater plenum. I painted it and lubed the pivot points so all is working smooth now.

Then I took out the plenum against the firewall. It's getting cleaned.

Then I lubed the flap pivot points on the engine side of the firewall and that fixed a nasty squeek and makes it move real nice.

I'll be putting it all back together soon and expect it should all work fine.

Make sure you don't kink the cables are put them in to much of a bind. Also when assembling make sure you don't get them upside down when you twist the controller up in the dash. beleive me it can happen!
