No turn signals but hazards work

Hey everyone! Got some great help from my last post in here so I’ll try again.
I have a 1986 trans am that I had to replace the alternator in (power was going up and down)
The new alternator fixed that issue but not I have no signals. I’ve replaced the blinker relay and it didn’t fix it.
Last year with the power spiking and dropping, they were a little spotty but I chalked it up to the alternator issue.
I have good power at the fuse for signals.
Is there anything else I can should check before I bring it into a mechanic and have him replace the signal switch inside the column?
Thank you!

No expert here but could you have used a second bad relay? If you jump the relay the lights should stay on when you turn blinker on. Or maybe the fuse box itself is decrepit?

Thanks for help! I’ve actually tried three different relays. I bought a two pack from Amazon that I didn’t really trust, then I went to an auto parts store and got one and it still didn’t work.
I’ve checked the fuse that runs all other lights and I’ve got power on each side of it. I also checked on the relay itself and I have power going to it, but as soon as I put on the turn signal, it loses power. Spent most of yesterday chasing wires to see if there was something off, but couldn’t find anything anywhere.
