- 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 is not present, 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.
