Will, I wish that were an option now. After trying to fix it, now I have no brake lights (or side, license, or reverse). I disconnected the anti-theft system under the passenger carpet, pulled the brake light cable, and disconnected power and ground to the aftermarket Hirschmann and still no lights. I gave up and ordered a new lamp relay. Really can't see anything else it could be.

If I have a problem with my Mercedes, I go to MercedesShop. If I have a problem with my BMW, I go to BimmerNut.
If I have a probem with my Dell, I reboot it. I was an engineer for them for 10 years and we blamed everything on Microsoft.
