Default Brake lights/Flasher issue

Recently discovered my 69’s brake lights weren’t working. Fuse is good and I replaced the brake light switch, but still no brake lights. Reverse lights work, as do the turn signals. Now I found out my hazard flasher lights aren’t working either. Is there a tie in there possibly? I guess my next step is to replace the round hazard light fuse, to see if that corrects the problem. I did have the wiring harness replaced last year but haven’t had any issues until now, tho I never tried the flashers until now since the new wiring.

Any advise on what else to check or do before I resort to bringing it to a shop? I can handle basic repairs but I have a hard time with electrical issues. Thanks for any thoughts on my next steps.

Brakes and hazard are on the same fuse. Make sure you power on both sides of the fuse. Then check for power on the brake light switch.
