Why is the Cadillac display screen dimming?
1 Answers
The display screen is damaged and needs replacement. It could be a system issue, try restoring it. Poor contact in the wiring could also be the cause. Check if there is frost on the battery terminals, clean the battery terminals. Inspect the central control screen wiring harness, unplug and reconnect the central control screen wiring harness connector, use a hair dryer to blow on it. Restart the system. Check if the remote control has power, inspect if the lock actuator's plug is loose or disconnected. Take it to a 4S shop for repair.
