My issue specifically is in regards to the mirrors, just like the title states. I just purchased the Trail Ridge mirrors last week, and while I was installing them this past weekend, everything works with the exception of the driver's side clearance light. I followed the included instructions to the letter, however, the clearance light still will not turn on, save for the first time I put everything back together. The heat, fold, power adjust, turn signals, and puddle lights all work on both sets, minus this one bit.

Sadly, while the mirror kits seems to be built quite well, Trail Ridge doesn't have any sort of contact information for me to reach out to for support.

Now, I'm not the brightest light bulb when it comes to reading electrical diagrams (many thanks for having those on the site), but I don't think I found anything that would point me in the right direction. I wanted to pick the brains of those far more learned than I before I immediately jumped into requesting a replacement part. Any assistance you can provide would be greatly appreciated.
