Parking lights/turn signals aren’t working

[93sierrak1500]

What’s going on y’all, long time no see. Turn signals on the entire truck won’t work and the parking lights aren’t coming on. I changed out all parking light bulbs and fuses and that didn’t fix my problem. When I turn the turn signal it will tick really fast but the light also won’t come on on the dash. What could the fix this? Thank y’all

I was having some similar issues a year ago. Check rear trailer and taillight wiring. I had one of these that crapped out and was the issue.

It’s in between the rear main connection. I actually replaced with the brand above, which is a good brand, just was showing one as an example.

Headlight switch?
You’ll probably need at least a test light for some basic diagnosis.

Does it happen with lights on and off all the same?

Found a picture of the one that shorted out.

You must be registered for see images attach

If you have one of these, remove it and just reconnect harness without it as a test.

I like the molded style like the picture from Amazon better, less exposed wiring harness to get damaged.

That’s the way it all was when I got truck. It was a 1 piece, but it looked like it had been butchered by someone.

My son's truck had a broken ground wire on the rear harness that caused similar issues. If your rear harness is dorked, check the Suburban harnesses in the junkyard. They typically have less butchery.
