Temperature control **** adjustments?
Back when I lived in an area that actually got cold in the winter I was having issues with my heater blowing out hot air. Now that I am getting ready to move to another winter state I wanted to fix the problem. I replaced the thermostat, flushed the heater core and checked the blend door for blockages. While checking the blend door I noticed that when the temperature **** is turned all the way to hot the blend door is not fully closed and when it is turned to cold the door is fully open before the **** gets all the way to the bottom of the cold/blue dial. so my question is: Can the temperature **** on a star gear that you can just pull it off and put it back on in the correct orientation or is there an adjustment in the cable somewhere? This is on a 1994 4x4 excab with the 5.8.
Thanks

And, in giant bold text there's:
Perhaps a previous owner removed/fixed/re-installed things without setting things all to full warm?

Full Removal Instructions:
1. Disconnect battery ground cable.
2. Release glove box to gain access to the A/C temperature cable (19988) at the heater air plenum chamber (18471).

13. Insert Temperature Control Cable Removal Tool T94P-18532-A on A/C temperature cable to release two of three locking tabs. Use a small flat-bladed screwdriver to release the third locking tab and remove A/C temperature cable from A/C temperature control bracket by pulling directly from A/C temperature control bracket.
14. Remove A/C temperature control bracket from vehicle, paying particular attention to routing of cable to aid in installation.

Route A/C temperature cable in the same manner as cable removed.
2. Install A/C temperature cable on heater air plenum chamber by aligning locating tab on the A/C temperature cable with locating position on heater air plenum chamber. Make sure the temperature blend door actuator post is aligned within the cable head cam.
3. Push A/C temperature cable over temperature control door cam until an audible click is heard indicating engagement. If a click is not heard, it will be necessary to visually ensure cable is fully seated in position.
