Charger Mirror Heater Failure + Error Code Fix Needed

Having dealt with a similar electrical fault on my 2013 Challenger, mirror heating issues during cold weather often trace back to wiring problems or control module failures. Last winter, the shop diagnosed a damaged wire harness between the door and mirror assembly. The temperature control system kept throwing codes because the circuit was interrupted. The heated mirror elements were intact, but the connection had deteriorated due to repeated door movement over time. For winter driving safety, functioning mirror heaters are essential. The repair involved replacing the wire harness and checking the control module connections. While not a severe mechanical issue, it requires careful diagnostic work since multiple electrical components interact with the heating system. Worth noting that these heating problems commonly appear after several years of use in Charger/Challenger models. Have a certified technician verify if its truly the wiring, sometimes moisture intrusion through degraded seals can cause similar symptoms and control module errors. The fix is definitely manageable but requires proper electrical diagnostic equipment to pinpoint the exact fault location in the circuit.

Thanks for sharing your experience. My 2016 Charger had the exact same rearview mirror heating problem last winter. The heater element completely stopped working and the error code kept showing up. After seeing your post, I suspect my car mirror might also have a damaged wire harness since the symptoms match perfectly. Vehicle safety is definitely a concern when driving with foggy mirrors in cold weather. Did you track how much the complete repair ended up costing? Also curious if youve had any other electrical fault issues pop up since getting it fixed?

Had the repair done last month, turned out to be exactly what I suspected. The car electronics specialist found a loose connection where the wiring meets the mirror plug. Total cost was 95€ for fixing the faulty wiring, which was much less than initially expected. The rearview mirror heater works perfectly now, even in cold weather conditions. No more error codes showing up on the temperature control system. The electrical fault was simpler to fix than replacing the entire heater element or wiring harness. Since the repair, all mirror heating functions have remained stable with no new issues appearing. The mechanic also checked the surrounding connections while doing the work, which helps prevent similar problems from developing. For anyone facing the same symptoms, getting it checked early helps avoid more extensive electrical repairs later.

I went to get it checked out yesterday after your helpful insights. The mechanic confirmed the wire harness issue in about 30 minutes of testing. The car electronics diagnostic showed the exact fault code you mentioned. The repair was straightforward, they fixed the loose connection and checked the heater element integrity. Total cost came to 120€ including the diagnostic fee. Much better than my previous experience where another shop wanted to replace the entire mirror assembly. Already tested the heating this morning in cold weather and the temperature control is working perfectly now. No more error codes. Really glad I got this sorted before winter driving season. The vehicle safety aspect definitely made it worth fixing right away rather than waiting. Thanks for steering me in the right direction with the wiring diagnosis. Saved me from an unnecessary expensive repair.
