Default Turn signal not working

A new day a new issue lol, this time it's the RF turn signal. It was working fine yesterday, but today it's not, the rest are working, also hit the warning flasher and works perfectly, just the RF signal not working. Not my strong area, but guessing guessing a relay, maybe...thoughts? On a 66 gmc 1500..

Have you tried changing the bulb? Another possible cause is the turn signal switch.

May be the tangs on bulb socket are not grounding in the hole, but odd that same bulb works when on warning mode?
What relay are you talking about?

After you fiddle with the socket and verify good ground, swap L and R bulbs to see if issue follows bulb or stays with socket, then I have some tests for you. Get an ice pick voltage tester. $7

Will try switching bulbs, but as you said odd that it works when E flasher is on. Will get back to ya in a bit. And thanks Azken, you are the master indeed.

Azken, it must've been a bad ground or bulb, I changed the bulb and sanded the little ground clips and its back to working again....at least until the gremlins get bored again...
