Hy DKMcGee, If you are using a digital meter to do your testing they will give a reading when in reality there are only milliamps of current there, not enough to light the light bulb. We know the turn signals work, so there must be a diminished feed to the turn signal switch from the brake light switch. Bill Hanlon posted a link to the trucks wiring diagram, check that to find which wire provides power to the turn signal switch and make sure there is real power there, use a test light not a digital meter, hope that helps.
