If the recirculation control cable can't be adjusted to work properly, replace the cable:
1. Detach the cable from the recirculation control linkage.
2. Detach the cable from the recirculation control lever, and remove it (see HEATER CONTROL PANEL DISASSEMBLY AND REASSEMBLY ).
3. Install the new cable in the reverse order of removal, then adjust the cable.
After installation, operate the controls to make sure they work properly.
