Here's the problem, everything operates perfectly fine with the lights off. Hazards and cruise control work fine.

Turn on the lights, my brake lights are illuminated. Hit the LEFT turn signal, the arrow stays illuminated on the dash, and the right side goes dim to normal tail light dimness, while the 3rd brake light and left side stay illuminated. Right turn signal operates like it's supposed to.

Also, when the truck is off and key is out of the ignition, I can turn on my headlights and if I push down on the lever to activate the left turn signal I can make the arrow illuminate on the dash and it'll do what I described above. The right turn signal does not come on as it's not supposed to with the key off.

Just wanted some input, I'm going to slide up under there tonight and check the connections on the column, I've heard they can come loose and cause a short.
