Models with Manual HVAC Systems only. This Service Information bulletin provides precautions to use when removing the HVAC control panel to prevent damaging the blower fan speed switch. When removing the control panel, if the fan speed switch wiring harness is pulled taught or becomes stressed, the switch may be damaged. If the connector (lower) portion of the switch becomes separated from the switch body even slightly (see Fig. 1 on page 2), the HVAC control panel assembly must be replaced. The switch itself is not
serviceable. The related instrument panel (IP) wiring harness must also be inspected and replaced if
any damage is confirmed. NOTE: For 2012MY Impreza, see TSB 10-78-12, dated 4/18/2012.
