Fresh/Recirculated Air Selector Switch
- Remove heater control panel. See HEATER CONTROL PANEL
under REMOVAL & INSTALLATION. Connect positive battery cable to terminal "h" of connector on back of control panel, and ground terminal "g". See Figure
.
- Connect 1000-ohm resistor between terminals "f" and "q". Ground terminal "o". Measure voltage between terminals "f" and "g". If battery voltage exists, remove jumper wire and 1000-ohm resistor. Go to next step. If battery voltage does not exist, replace heater control panel.
- Push indicated switch, and check continuity between appropriate terminals. See FRESH/RECIRCULATED AIR SELECTOR SWITCH TEST
table. If continuity is not as specified, replace heater control panel.
