    Hi All

    2019TRD
    My trailer is not receiving turn signal or brake light voltage. I have running lights and electric brake voltage. I am measuring voltage at the truck 7 pin which looks factory new. All fuses look intact, could this be the signal relay ? How would i test this? Any help is much appreciated.

    Thanks
    Robert

    Check your TOWING Fuse (25A) in the underhood fuse box, if that's good it's very possible the Combination Meter (Instrument Cluster) has an issue.
