I have a 1996 GT that I bought previously modified to a moderate extent, and I’m having trouble finding an issue that would be causing my turn signals not to work. It seems to be upstream because when I hit the switch, they do not trigger the flasher (which does work). But they also don’t illuminate the flash indicator on the dash neither. I figured it was the multi-purpose switch, but everything else on it works such as the wipers and the brights. Also, nothing on my gauge cluster works. Don’t know if that correlates but I will include that as well. I pulled it out and found little to no indications of a problem. Any ideas? Maybe a bad ground? And if so what ground am I missing, because I got all that were under the hood with wire brush and a flap disk and reseated them. Any helpful info is much appreciated, thanks.
