95 Accord Heater question
 

95 Accord LX. Owned in family since new. 110,000 miles on it now.
Having problem with the temperature control knob. Knob is not cracked
like has happened six times on my '92 Accord. Normal sweep of control
knob is from cold at nine o'clock position to full hot at 3 o'clock.
Knob now only able to rotate from about ten thirty position to one
thirty. Knob will move past these spots, but will rebound on it's own.
Disconnected the hot water valve control cable at the valve, and valve
operates fully and easily. Cable seams to move a door or something on or
in the heater box under the dash as well as the water valve.
I don't think the problem is with the cable, but has something to do
with the door functions at the heater box.
Am I on the right track? Has anyone been there before and do you have
any ideas? bob
