Mercedes-Benz Sprinter 3500 all tail and marker lights out, circuit protection issue suspected after temporary clearance light function on Mercedes-Benz Sprinter 3500

Some Mercedes-Benz Sprinter 3500 owners report experiencing issues with all tail and marker lights being out after using the temporary clearance light function, which may indicate a circuit protection problem. These issues could stem from a surge caused by the temporary clearance light function that trips a fuse or damages a relay. Additionally, there may be faults in the wiring related to the temporary clearance light function affecting the tail and marker lights. Owners are advised to check the fuses associated with these lights for any that may have blown and inspect the wiring harness for visible damage or loose connections. Testing the relays in the lighting system is also recommended to ensure proper functionality. If these troubleshooting steps do not resolve the issue, consulting a professional mechanic or electrician for further diagnosis and repair is advisable.
