Right rear turn signal not working?

Okay, first I would check the fuses (8) that run the system which goes through the BCM, (yellow wire) Here is the wiring diagrams that show you how the system works, and which fuses run it. I would check the BCM right run signal output at the PCM using a test light to make sure the BCM is working and then either find the brake in the wire or just run a new wire.

Here is the BCM location as well. Check out the images (below). Please let us know what happens.

Thank you I’ll try this today and get back with you.

Okay, I tried all the fuses. I programmed a new BCM, and I’m getting the same problem. Broken wire is all I can think of now. I’m waiting on an open circuit tester to come so I can maybe trace down this right rear turn wire, Ken would you happen to have a wiring diagram from the under-hood fuse box too, so I can start after it. thank you.

Did you test the output of the BCM (yellow wire) to see if it blinks? I would test right at the BCM if it blinks run a new wire. Do you need more diagrams besides the ones I have for you in the above images?

I’ll try that then as soon as I get back to the van, so for the right rear turn it should be the yellow or dark green out of BCM. Thank you

Oopps, yep, my bad, sorry, dr/grn wire. Let me know and have a nice weekend.

You too sir, thanks again.

Okay, finally got to get back to the van, I couldn’t get any current out of the dark green wire coming out of BCM. I used an open circuit tester from the right rear harness to turn wire and couldn’t find any breaks in the wire. Where should I go next? Thank you

Found it Ken it was the BCM 6 fuse! Thank you for your help.

Glad you could get it fixed, thanks for letting us know. Please use 2CarPros anytime we are here to help.
