Thanks Schultz.
I do have a manual for the truck.
They do have instructions in there for replacing the turn signal, but I didn't see anything about the hazard.
If that was all just one single unit, that would make sense as the how the turn signals have been behaving.
I did see the holes underneith the steering wheel, but they are very deep and narrow - I couldn't get my eyes and a flashlight staring in there at the same time.
This should make it much easier! Thanks!
