Chime Inoperative
WARNING: This page is about a different car, the 1999 Pontiac Grand Am and 1999 Oldsmobile Alero. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect Body Control Module (BCM) 16-pin (Gray) connector C-1. BCM is located below right side of instrument panel near blower motor. Turn ignition on. Use DVOM to measure voltage between BCM connector C-1 terminal B8 (Brown wire) and ground. See WIRING DIAGRAMS . If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step 6 .
- Use DVOM to measure voltage between BCM connector C-1 terminal A8 (Purple wire) and ground. If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step 8 .
- Turn ignition off. Disconnect BCM 24-pin (Gray) connector C-2. Turn ignition on. Use DVOM to measure voltage between BCM connector C-2 terminal B9 (Pink wire) and ground. If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step 10 .
- Turn ignition off. Disconnect BCM 24-pin (Pink) connector C-3. Turn ignition on. Use DVOM to measure voltage between BCM connector C-3 terminal A12 (Orange wire) and ground. If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step 12 .
- Use DVOM to measure voltage between BCM connector C-3 terminal B1 (Orange wire) and ground. If battery voltage is indicated, go to step 19 . If battery voltage is not indicated, go to step 14 .
- Backprobe with DVOM to measure voltage between right instrument panel junction block connector C-1 terminal C4 (Brown wire) and ground. If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step 18 .
- Repair open in Brown wire between right instrument panel junction block and BCM. After repairs, recheck system operation.
- Backprobe with DVOM to measure voltage between left instrument panel junction block connector C-1 terminal B9 (Purple wire) and ground. If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step 17 .
- Repair open in Purple wire between left instrument panel junction block and BCM. After repairs, recheck system operation.
- Backprobe with DVOM to measure voltage between underhood wiring harness junction block connector C-3 terminal C4 (Pink wire) and ground. If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step 16 .
- Repair open in Pink wire between underhood wiring harness junction block and BCM. After repairs, recheck system operation.
- Backprobe with DVOM to measure voltage between right instrument panel junction block connector C-3 terminal A12 (Orange wire) and ground. If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step 18 .
- Repair open in Orange wire between underhood wiring harness junction block and BCM. After repairs, recheck system operation.
- Backprobe with DVOM to measure voltage between left instrument panel junction block connector C-1 terminal E7 (Orange wire) and ground. If battery voltage is indicated, go to next step. If battery voltage is not indicated, go to step 17 .
- Repair open in Orange wire between underhood wiring harness junction block and BCM. After repairs, recheck system operation.
- Replace underhood wiring harness junction block. After repairs, recheck system operation.
- Replace left instrument panel junction block. After repairs, recheck system operation.
- Replace right instrument panel junction block. After repairs, recheck system operation.
- Replace BCM. See BODY CONTROL MODULES - ALERO & GRAND AM article. After repairs, recheck system operation.
