⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems to prevent shocks and further damage
•Ensure the vehicle is off before inspecting or replacing fuses

Symptoms

•Frequent blowing of fuses
•Electrical components not functioning (e.g., lights, radio, power windows)
•Burning smell near fuse box
•Flickering lights or intermittent electrical failures
•Check engine light illuminated (possibly due to electrical issues)

Diagnostic Steps
