My 2015 Forest River Georgetown 364TS has me stumped. The brake lights completely stopped working, but everything else is fine - tail lights, turn signals, hazards all work perfectly. Already swapped the brake switch and traced what wiring I could reach. Two different shops have looked at it and burned through hundreds of dollars with no results. Oh, and my backup camera is acting weird too - stays stuck on the right view unless I hit the left turn signal, only switches to reverse when backing up. Can't find wiring diagrams anywhere for this model.
Georgetown brake light failures commonly trace to corroded chassis connectors, failed body control modules, or damaged harnesses between the chassis and coach. The camera issue suggests a shared ground or signal problem in the lighting circuit.
Georgetown brake light failures with working tail/turn signals point to a few notorious trouble spots. Since you've already replaced the brake switch and had professional diagnostics, this is likely a deeper electrical gremlin hiding in the chassis-to-coach interface or the body control systems.
The camera behavior you're describing is actually a huge clue - it suggests the brake light circuit and camera switching circuit share a common connection that's compromised. This commonly happens at ground points or in the main lighting harness.
Georgetown models commonly experience corroded ground connections where the chassis meets the coach body. You'll find the main lighting grounds near the rear axle area, typically bolted to the chassis frame. These connections corrode from road salt and moisture, creating exactly the symptoms you're seeing.
Disconnect battery power before beginning work. Remove each ground connection, clean both the terminal and mounting point with a wire brush until you see bright metal, then reassemble with dielectric grease. Pay special attention to any grounds that show green corrosion or feel loose.
Forest River Georgetown models use a junction box where chassis wiring meets coach wiring, usually located under the rear of the RV. This box is a common failure point because it's exposed to road debris and moisture. Water intrusion causes terminal corrosion that selectively affects different circuits.
You'll need to remove the junction box cover and inspect each terminal. Look for green corrosion, loose connections, or terminals that pull out easily. The brake light feed typically uses a heavier gauge wire than turn signals, so it may be on a separate terminal that's failed while others remain functional.
Georgetown models from this era use electronic control modules to manage lighting functions. When these modules start failing, they create bizarre symptoms like your camera staying stuck on one view. The brake light circuit may be controlled by a different section of the module than turn signals, explaining why some functions work while others don't.
The module is typically located behind interior panels near the driver's area. You'll need a qualified technician with diagnostic equipment to properly test module function, but you can check for obvious issues like corroded connections or water damage to the module housing.
The main lighting harness on Georgetown models runs along the frame rail and is vulnerable to damage from road debris. Understanding your RV's electrical system layout helps when tracing these circuits systematically.
Start at the brake switch and follow the circuit toward the rear. Look for sections where the harness might contact sharp edges, pass through tight spaces, or be exposed to road spray. Common damage points include frame crossmembers and areas near the generator or slide mechanisms.
Use a multimeter to check continuity from the brake switch through to the actual light assemblies. Disconnect the battery or turn off the main electrical disconnect before working on any electrical connections to prevent shorts or injury. You're looking for the point where 12V disappears from the brake circuit while remaining present in the turn signal circuit.
The fact that your camera responds to turn signals but not brake activation suggests the camera switching relies on lighting circuit signals. Many Georgetown installations tie camera switching to the lighting circuits rather than using independent switching.
This means fixing your brake light problem will likely resolve the camera issue as well. The camera system isn't getting the brake signal it needs to switch to reverse view because that signal is interrupted somewhere in your brake light circuit.
Since two shops have already worked on this unsuccessfully, I'd recommend finding a shop that specializes in RV electrical systems or heavy truck electrical work. They'll have the proper diagnostic equipment and experience with chassis-to-coach electrical interfaces.
Ask specifically about load testing the brake light circuit and checking the body control module operation. Many automotive shops don't have experience with the more complex electrical systems used in Class A motorhomes.
While hunting for the root cause, consider installing a temporary brake light activation system. You can wire LED brake lights directly from the brake switch with an independent circuit, bypassing whatever's failed in the main system. This keeps you legal and safe while working through the diagnosis.
This is a complex electrical issue that commonly stumps shops unfamiliar with Georgetown electrical architecture. The camera symptoms actually help narrow down the problem area, so use that information when working with your next diagnostic technician.
