Talking Right Turn Malfunction--fixed!!!!

Malfunction was intermittent at first and then automatic at start up. Been like that for months. Read and reread all the previous posts on this. Figured the LCM was toast. Bought and installed a new LCM last week, went back to intermittent--improvement!!! Dropped the bumper fascia today and was determined to find the problem. Opened the headlight and low and behold, a blue wire was hitting the metal bracket around the headlight housing. It was rubbed raw. Re-insulated wire and also a small portion of the bracket it was hitting. Fixed the problem and it looks like for good. Opened the left (driver) headlight assembly as well to check it. No problem there. Here's a picture to show where the wire is rubbing. This is the passenger (right) side headlight assembly. The assembly is upside down and I have removed the actual headlight. Pretty simple fix. If you just replace the LCM without finding the short, the malfunction will eventually come back. As you can tell from the pictures, all the wires are in bad shape. I re-insulated them as best I could.

If you don't have this as a bookmark, do it NOW. Indispensable resource.
