Rebel turn signal

[Subourbon]

Hey all,

82 k20 suburban 6.2 diesel 4x4 here.
It started out as intermittent but, now it's constant.

With lights off: indicate left, turn signal clicks. Lights up forward work, but not in the rear. Turn signal self cancels. No issues anywhere else. Brakes reverse etc works. The clicking woth lights off us a tad slower than when I'm indicating right however

With lights on: everything is illuminated including problematic light (its not the light bulb). But when I indicate left, no more clicking noise, no flashing at the front nor at the rear. Indicator self cancels.

Now I replaced the bulb anyways just coz. No change. Can't imagine its in the fuse box coz there's one use for both side I believe.

That would lead me to think its in the light switch? Are those somewhat easy to work on or should I just replace the unit.

Unless one of you knows a trick...
Not really the end of the world I can definitely live with it for now but it'd be fun to have all lights working!

Let me know if you guys have any ideas... appreciate it everyone!

Oh, and hazards...

Lights off everything but rear left flashes.

Lights on everything but rear left flashes. So the front left seems to kick back on with flashers on. Fingers seem to really point at light switch.

Would it be the turn signal on the column, or the light switch module behind the bezel and dashboard though. That's what I'm not sure of now.

I had a similar issue and the new bulb I had was bad. A new new bulb from the parts store solved the issue.

If that is not it then perhaps the socket is bad or the turn signal switch.

But, I would double check that bulb with new and put a little dielectric grease on the contacts.

You might just get lucky!

Goldie driver,,

Upon further inspection, the bulb that was already in there is fine. With lights in, there the running light/brake lights, and reverse. And the small turn signal bulb. And it's on. It just doesn't flash. So there's power going to it...someone said grounds. So tomorrow at first light il track down the grounds innthe rear and fingers crossed it'll work

It fixed itself. I messed around with the socket and light switch, so far it seems to be working.
Yay! Now I have a trans that won't shift in 3rd so gonna figure that out

I had similar intermittent issues with rear turn signal on my step side. Adding a dedicated ground wire took care of it for good.

It didn't fix itself. It's foolin' you. Check that ground behind the light bezel to the socket.

Snoots,

You're probably right. It's in the shop actually since my last message lol. Rebuilding trans. Geez parts are hard to source.
I'll look into it when she's back home.
I miss my truck lol
