A dead rear camera feed usually comes from a head unit glitch, a lost power/ground path, or a damaged camera or trunk harness.
If your Charger hits reverse and the screen stays black, backing up turns into guesswork. The bright side: most camera failures come from a short list of causes, and you can narrow them down without throwing parts at the car.
The check order below starts with no-tools fixes, then moves to the spots Chargers often fail: settings, infotainment restarts, fuses, the trunk-lid wiring loom, connectors, and the camera module. You’ll also see when to stop and book service.
What “not working” looks like on a Charger
People use the same phrase for a few different failures. Identify the symptom first so your next step makes sense.
- Black screen in reverse: the display switches, then shows black.
- Blue screen or “camera unavailable” message: the radio asks for a signal and gets none.
- Intermittent feed: it works, then drops out after bumps or trunk movement.
- Video is fine, guidelines are gone: overlay or settings issue.
- Blur, haze, streaks: lens grime, moisture inside the camera, or a failing sensor.
Safety note before you start
Do checks parked on level ground with the parking brake set. If you must test in reverse, keep a clear space behind the car and use a spotter. If you remove trim, use plastic trim tools to protect clips and panels.
Backup camera not working on a Charger: first checks
Clean the lens and the area around it
Road film on the trunk and fascia can turn the feed into a gray smear, especially at night. Clean the lens with mild soap and water, then dry it. Skip harsh solvents that can haze plastic.
Confirm the screen is switching into camera mode
Shift into reverse with the ignition on. If the screen never changes, the issue may be the head unit, shifter input, or reverse signal. If it does switch modes and goes blank, the radio is trying to show the camera.
Check camera-related settings
On many Chargers, the camera overlay and related prompts can be toggled in infotainment settings. If video works but guidelines don’t, start here. Menu labels vary by year and trim, so use the feature index in the official manual. Mopar’s Dodge Charger Owner’s Manual (PDF) is a reliable place to confirm where those menus live.
Do a safe infotainment reboot
A frozen head unit can kill the camera feed even when the camera itself is fine. Try a clean sleep-cycle restart before you touch wiring.
- Park, set the brake, and turn the ignition fully off.
- Open the driver door and wait a minute so modules go to sleep.
- Restart the car and test reverse again.
If your radio has an on-screen restart option, use that instead of disconnecting the battery. A battery pull can create fresh problems like lost presets or window indexing.
Dodge Charger Backup Camera Not Working
After the fast checks, treat this like a signal path problem: camera power and ground, video signal to the radio, and radio software that can render the image. Work in order so you don’t chase the wrong part.
Step 1: Check for open safety recalls tied to electronics
Before you buy parts, run your VIN through the official recall lookup. Some campaigns involve infotainment behavior that can show up as camera glitches, and recall repairs are free. NHTSA’s recall search lets you check by VIN or by make and model.
Step 2: Verify reverse lights and the reverse signal
If your reverse lights are out, you may have a shared fuse, a wiring break, or a switch/signal issue. Have a friend confirm the reverse lights come on. If they do not, fix that first.
Step 3: Test fuses with a meter, not your eyes
Hairline breaks can fool the eye. Use a fuse tester or a multimeter. The camera circuit may be tied to the radio, a body module, or rear lighting circuits depending on year.
- Use your manual to find the right fuse layout for your year.
- Test with the circuit powered, not only out of the car.
- If a fuse opens again, stop replacing it and look for a short in the trunk harness or camera lead.
Step 4: Inspect the trunk hinge wiring loom
If the camera cuts out when you open the trunk, start here. The bundle that runs through the trunk hinge flexes each time the lid moves. Over time, that flex can crack copper inside the insulation.
Quick test: with the car on and the screen in reverse (use the brake and a spotter), gently wiggle the loom where it bends. If the image flickers, you’ve found a strong lead.
| What you see | What it often points to | What to try first |
|---|---|---|
| Screen switches to camera, then black | Power/ground loss, dead video signal, or failed camera | Fuse test, loom wiggle test, connector reseat |
| “Camera unavailable” message | Radio fails a camera input self-check | Sleep-cycle reboot, connector check, scan for faults |
| Works after restart, fails later | Radio glitch, heat-related fault, or weak voltage | Reboot, battery/charging test, software check at service |
| Flickers with trunk movement | Broken wire in hinge loom | Visual check, continuity test, harness repair |
| Blur or haze that returns | Moisture inside camera housing | Inspect for water tracks, plan for camera replacement |
| Guidelines missing, video ok | Settings off or overlay fault | Settings check, reboot radio |
| Fails after rain or wash | Water at a connector or seal | Dry connectors, check gaskets, use dielectric grease on seals |
| No change after any restart | Hard wiring fault or dead camera | Power test at camera connector, scan for codes |
Step 5: Reseat connectors at the camera and radio
A slightly loose connector can work on smooth roads and fail on rough pavement. Disconnect, inspect, and reconnect.
- At the camera: check for corrosion, bent pins, or water tracks.
- At the radio: label plugs and follow trim steps from your manual to avoid broken clips.
If you see corrosion, clean pins with electrical contact cleaner, let them dry, then reconnect firmly. Use dielectric grease on the seal side only, not on the metal contacts.
Step 6: Rule out low battery voltage
Low voltage can cause infotainment oddities: slow boot, random reboots, and blank screens. If cranking feels weak or lights dim at idle, test the battery and charging system.
When software is the culprit
On many Chargers, the rear camera feed runs through the infotainment stack. A camera failure can be a bad camera, or the radio failing to decode and show a valid stream.
Signs you’re chasing a software glitch
- The camera works after a restart, then fails again days later.
- The screen freezes in other menus too.
- Bluetooth, audio, or navigation misbehave at the same time.
A dealer or a shop with factory-level scan tools can read stored faults, check module versions, and confirm if an update is available.
Rear visibility systems sit inside U.S. safety rules, including FMVSS No. 111. If you want the legal definition of a “rear visibility system,” the text is public at 49 CFR 571.111.
How to tell if the camera module has failed
If fuses test good, wiring looks clean, and the radio still shows “no signal,” the camera itself may be dead. The camera is a sealed unit on many trims, so moisture inside often ends in replacement.
Clues that point to a bad camera
- Fogging behind the lens that won’t clear.
- A stable no-image state that never changes with trunk movement.
- Distortion with permanent lines or a rolling picture.
Repair choices and what each one usually includes
Use this as a shopping list for diagnosis. It also helps you talk to a shop without getting sold a part you don’t need.
| Fix type | Typical scope | When it fits |
|---|---|---|
| Sleep-cycle reboot and settings check | Restart modules, verify camera menus, clear minor glitches | Intermittent failures, frozen screen in other areas |
| Fuse and power-path repair | Test fuse, trace a short if it returns | Reverse lights act odd, camera is fully dead |
| Trunk loom wiring repair | Repair broken conductors at hinge, rewrap harness | Camera drops out with trunk movement |
| Connector clean and reseat | Dry moisture, clean corrosion, lock connectors | Fails after rain, returns after drying |
| Camera replacement | Swap camera module, verify video and guidelines | Moisture inside lens, distortion, no signal with good power |
| Scan and software update | Read stored faults, check module versions, update radio | Repeat glitches, multiple infotainment features misbehave |
When to stop DIY and book service
Some cases are better handled with scan tools and wiring diagrams:
- Fuses keep opening after replacement.
- Water keeps entering the trunk area and you can’t find the path.
- You repaired wiring and the fault returns within days.
Ask the shop to check stored faults in the radio and body module, then confirm software versions. If a recall applies, start there since it can pay for parts and labor.
Habits that help the fix last
Keep water out of the camera pocket
A gentle rinse is fine, but skip high-pressure spray at the trunk handle area. Water can be driven past seals into connectors.
Give the trunk loom slack
If the loom is pulled tight, each trunk open strains the same bend point. After any repair, route the harness so it has a smooth curve through hinge travel.
Use the camera as a screen, not as your only check
Even with a working camera, do a head check and mirror scan. Federal rear visibility rules are meant to reduce blind zones, yet they don’t replace basic awareness. The rule materials are public, including NHTSA’s Rear Visibility final rule PDF.
A test order you can save
Use this order and stop when the image returns:
- Clean the lens and confirm the screen switches into camera mode.
- Check camera settings and do a full ignition sleep-cycle reboot.
- Confirm reverse lights work.
- Test relevant fuses with a meter.
- Inspect the trunk hinge loom and do a wiggle test.
- Reseat camera and radio connectors; dry any moisture.
- Test battery voltage under load.
- If power and wiring test clean, plan for camera replacement or a scan.
