Thanks. I’m having trouble getting the left front turn signal out of the BCM as well as the right rear turn signal.

Also, there are several color-coded plugs on the BCM and the wiring diagrams provided do not specify which connector is which.

Yep, if the fuses are good and bulbs and grounds the BCM is bad which is common. Here is how to change it out. Check out the images (below). Please let us know what happens. You can get a preprogrammed unit by searching Google or Ebay.

I appreciate your help, however I found out through some probing that the BCM was not getting voltage on an always hot wire and traced that to the fuse panel whereas it turns out there was a missing fuse. I wasn’t sure if this fuse was missing on purpose when I first inspected the vehicle because I’m unfamiliar with it, but with the wiring diagrams you provided I was able to solve the problem.
