Oldsmobile Aurora wiring issues causing outside rear lights to blink continuously and interior lights malfunctioning on Oldsmobile Aurora

Some Oldsmobile Aurora owners report experiencing wiring issues that result in continuous blinking of outside rear lights and malfunctioning interior lights. These problems may stem from a faulty headlight switch, which can lead to erratic operation of both headlights and rear lights. Additionally, electrical system malfunctions are reported to cause failures in headlights and interior lights while driving at any speed. Some owners have found that replacing the Body Control Module (BCM) with a used one can help address flickering hazard lights and dash panel issues. Repairing door wiring, particularly at the driver's side, and inspecting passenger side wiring may also resolve these electrical problems. Others have noted that tapping the dash area above the instrument panel can indicate issues with the instrument cluster assembly or electronics. Furthermore, checking the Rear Integration Module (RIM) for power issues related to interior and courtesy lights, along with testing the relay's hot wire, can assist in diagnosing the underlying issues. Prompt attention to these concerns is advised to ensure proper functionality of the vehicle's lighting systems.
