Hi everyone. I am new to this group. I recently decided to buy my first chevy and went and found this 75 Chevy cheyenne. It is a K20. I have certain problems right away with it, but for most part fell in love with her as soon as i saw it. The first problem i am having at moment is when i try to use the turn signals all four light up if i try passenger side. when i try to use drivers side only the drivers side in rear lights up but both front ones. Can anyone give me ideas
