    I have a 07 freightliner columbia with turn signal lights and clearance lights problem. When truck has the turn signal on either way they work fine and turning on the headlights turn signal light stop working they stay on outside of truck and inside the dash and when u turn off head lights and just leave the clearance lights all the light on truck start flashing

    Does it do it without a trailer attached? If yes then the problem is in the truck, if it only does it with the trailer attached then the problem is in either the trailer or the 7 wire cord, plug, or socket. It sounds like you have a weak ground or a short between the turn signal and marker light circuit. Check the 7 wire plug for corrosion or a bent/broken pin, check your tail lights for corrosion or broken wire, maybe even an internal short in one of the tail light bulbs. Also check your front turn signal/marker light wires for corrosion, short, or broken wires.

    In my 06 Century Poor ### Management truck I had to work on the wiring on both front corners. I would say it's a Freightshaker thing.

    Does it have fuse for DRL? Try taking that out.
