Guys I need a little help. I have a 1980 Chevy SWB. When I purchased the truck, the turn signals did work. Now, a couple of years later and many modifications later, including a factory tilt column upgrade and surface mounted autometer upgrade, the turn signals dont want to work. To be exact, when I initiate the turn signal one way or the other, the light comes on on the dash and on the outside but it does not blink. I have replace the flasher but that did no good. Anyone have any suggestions?
