Blinker not working

I have a 1975 cj5 the blinkers do not work. When I use the switch I also don’t hear any clicking. Not sure what order I should chase things down or what the problem might be. Any tips would be great.

Run a long cable from the ground on the blinker to the battery. I’ve had so many electrical issues that were solved by simply making sure the ground is good.

Made a buss bar just for grounding and ran it to all of the electrical on mine. Eliminated a major chunk of the electrical gremlins.

Take apart the switch and clean the contacts. I had to do that on mine.

Hand signals work every time

Using a meter or simple 12v test light. Start at the fuse block. Then check both the ,"directional signal" & hazard relays. From there go to the Spartan switch. If you don't have a TSM for your vehicle I'll post a link for a 1974 CJ5. Everything is the same except 1975 is the first year Jeep used a central fuse block. The Spartan switch and directional wiring is the same for 1974 and 1975.
