Hi all, new to the site so thank you in advance for youre help. I have recently been doing some work on the truck and now have the error code B1163-15 coming up for the left mirror heater output failure. I am at a loss for how to remedy the error and any help would be appreciated. FYI i did change door handles to black via the factory covers and also changed lights to LED interior if that is part of the issue. Thanks again!
