Troubleshooting No Left Turn Signal or Running Lights on 2014 Jeep Grand Cherokee With RM-154


Followed video to the T but I still have no running lights or turn signal to driver side of towed vehicle


Expert Reply:

If everything works but the running lights and turn signal after you installed the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 it sounds like you may just have a weak ground; this is often the cause of these types of issues so you'll want to make sure your grounds are securely attached to bare metal surfaces free of any paint, dirt or corrosion of any kind. Also check your wiring thoroughly to ensure there are none that are crimped, broken or otherwise damaged and your connections are secure and this should ensure your lights work.
