My front passenger side blinker won’t work, but the bulb lights up. I had to replace the buckets recently and since then the blinker won’t work on either bucket assembly. The other 3 work fine and so do the headlights.

I would start by checking the fuse on the BCM this guide can help. Also, I have included the blinker wiring diagrams so you can see how the system works and which fuses to check.

I have included how to change out the BCM in case you need it, if the BCM is bad it should come up in a CAN scan, you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon here is a video to show you how. You can get a preprogrammed BCM by searching Google or Ebay.
