1) Remove right instrument panel sound insulator. Remove temperature control cable from heater housing. Move temperature control knob from full cold to full hot setting. If cable binds or pulley does not rotate freely, replace cable. Set temperature control knob to detent position halfway between full cold and full hot setting. 2) If control cable pulley is offset by 5-10 degrees toward full cold side, no adjustment is necessary. See Fig. 2. If control cable pulley is offset to
