Heater Controls and Control Panel

REMOVAL & INSTALLATION



While reasonably simple to remove, the control panel is connected to the various systems by a cluster of wires, cables and vacuum hoses. Use caution during removal and installation not to damage or crimp these items. Label items as they are disconnected. Work gently and don't force the panel into position; cables and linkages must move smoothly throughout their entire range of travel.

  1. Disconnect the negative lead to the battery.
  2.  
  3. Remove the soundproofing and and side panels on both sides of the center dash.

  5. Remove the radio.

  7. Loosen and remove the screws holding the control panel cover and move the cover aside.

  9. Remove the control panel; carefully move it away from the dash as far as possible. Repairs or replacements can now be performed on the back of the control panel. If it is necessary to replace a lever assembly, note that the knob on the front pulls off, allowing the lever to slip through the slot. Any needed adjustments should be performed (to cables etc.) at this time.
