2003 Buick Rendezvous 6 cyl Front Wheel Drive Automatic 56000 miles
BCM module seems to be loosing power. Allarms keep on going off in random. They reset or trigger when tapped on stearing wheel. Buick dealer mechanic works on it for last four weeks. He changed BCM - no improvement. He plugged in temporary or disconnected a number of switches and sensors that work with BCM - no improvement. He found couple wires with stripped unsulation - no improvement after repair. Mechanic is still going through ground points, wires and connectors. Problem affecr a power in a way that there are no codes set indicating problem. Diagnostics check o.K. Or don't work at at all due to interrupted communication.
After 4 weeks - it looks like a challenge. What would you say gentelmen?
have the same problem?
