My turn signal quit working i checked the fuses and the bulbs and put a new turn signal switch in it and the turn signals still aren't working what else could it be

Usually when you get at the turn switch, you can use a jumper wire to bypass the turn switch and make the turn signals dance. If they won't work with the jumper, the problem isn't the turn switch. Maybe a problem with flasher or wiring issue in steering column?

Did you check for voltage at the turn fuse? Goes hot with the key on. Use a test light to check for voltage.

Suspect a signal flasher located under the drivers dash

Have you check the turn signal relay?? They usually located under the hood.
