How To: Deluxe Heater Control Lever Replacement

[WTX-65LWB]

Hello All!

Thought I would put together a quick tutorial on replacing the levers and cables on a Deluxe Heater Control unit. Pretty simple job that can be accomplished in about an hour once the control unit is out the truck. Hope this helps!

The problem - broken soft pewter control levers in the deluxe heater control unit




The solution - replacement steel levers from Old Air and new control cables (I purchased both through LMC).




Step 1 - Remove the old cables by removing the 1/4" fasteners and retaining clips.


Note - One cable connects to the front half of the lever near the control face. It is kind of pain to get to.


Step 2 - Remove the Defrost Hose Bracket to gain easy access to lever fulcrum pin.


Step 3 - Remove the lower bracket and blower switch (the switch connects into a groove in the middle lever).


Switch Removed


Pay attention to the bushing - the Old Air kit comes with a new one but don't lose it if yours does not.


Step 4 - Remove any remaining knobs (may have to brake them to remove them).


Levers ready to be removed - notice the distortion in the soft metal.


Step 5 - Drift out the fulcrum pin (a few taps on the pin is all it takes)


Components removed.


Control Unit stripped down and ready for reassembly.
