Dead Window Switches Plague Viper, Regulator Issues Surface

Working on a 2013 Dodge Challenger, I encountered identical window regulator initialization errors. The complete power window failure across all doors typically points to a central electrical problem rather than individual window motors or regulators. In most cases, this stems from a failing body control module (BCM) or corrupted window initialization settings. After disconnecting the battery, the window system often needs reprogramming. The diagnostic process revealed no issues with the actual door panels or window motors. The fix involved: 1. BCM reset procedure 2. Window initialization sequence 3. Testing power distribution to door modules 4. Checking ground connections behind door panels This was not a severe mechanical issue, but rather an electrical glitch common in these models. Before replacing any window motors or regulators, have the shop verify the BCM functionality and perform the initialization sequence. The car electronics in these models can be sensitive to voltage fluctuations. The window troubleshooting process is systematic, starting with the least invasive solutions. Many shops jump straight to component replacement when the fix might be much simpler.

Really appreciate the detailed response about the window controls. Had similar readings on my diagnostic and followed your suggestion about the BCM reset and initialization sequence. Your power window troubleshooting steps helped avoid unnecessary parts replacement. Just curious, what was your final repair cost for the BCM work? Also wondering if youve had any recurring issues with the car electronics since the fix? Would help to know what to expect if the problem shows up again.

After checking with the mechanic last week, the window regulator initialization error was successfully resolved. The repair included replacing the vehicle battery, which turned out to be the root cause affecting the car electronics and window controls. The total cost was 290€ which covered both parts and labor. The voltage issues were causing the window switch system to malfunction, but since the battery replacement, all window controls have been working flawlessly. The car electronics are now stable and the window reset procedure was completed without any errors. For what its worth, I havent experienced any recurring issues with the window controls in my Dodge Challenger since the fix. The mechanic mentioned that maintaining proper battery voltage is crucial for these electronic systems to function correctly. The window initialization process has remained stable, suggesting the original problem was indeed power-related rather than a mechanical window regulator issue. If you encounter similar symptoms again, definitely check the battery voltage first before pursuing more complex repairs. A simple voltage test can save significant diagnostic time and costs.

Thanks everyone for the helpful advice about window troubleshooting. Just wanted to close the loop on my Viper situation. Finally got it fixed yesterday, took it to my regular mechanic who did exactly what was suggested here. Turned out the car electronics were acting up due to a failing battery, just like mentioned. Total bill came to 310€ for the new battery and labor. The window controls started working right after the battery swap and window reset procedure. No need for any window regulator replacement, which would have cost way more. The door panels didnt even need removal in the end. Mechanic just performed the initialization sequence after installing the new battery. All window switches are now responding perfectly. Really glad I checked here first, saved me from an unnecessary expensive repair. PS, For anyone searching later: The car electronics can definitely act weird with a weak battery. Worth checking that first before assuming worst case scenarios with window regulators.
