C4 Turn signal not working
My 1988 c4 corvette was just started up recently after a full transmission replacement. I started it up and tried turning on my blinkers and they refuse to work. They don’t even try. I replaced my blinker relay and nothing changed. My bulbs in my digital gauge are going out and need to be replaced soon. Could that be the reason? When I put my groundings on could that be the issue, I put the two slave cylinder groundings and what I assumed was one that went to the exhaust all together on one bellhousing bolt. My slave cylinder bolt holes were widened and I cannot fit the groundings in the new holes unfortunately. If it’s not what else should I replace? Most of my bulbs are all out around the outside of the car as well and I’m just not sure where to start exactly.
