I'm looking for a diagram for mine right now. The hot/cold knob on mine is linked to a lever on the driver side of the heater box under the dash. This has a gear that drives the gear that diverts the air either over the heater core or from the outside vent.
My problem is the lever is worn out and the gear slipped causing the position of the knob to be incorrect for heat. I pried the lever out and rotated the gear as a temporary fix to get heat.
So far I haven't found any diagrams or parts to fix it...maybe a junk yard is required.
