💡 What are the main reasons an accessory power relay stops switching correctly in a car's electrical system? A worn-out switch contact or internal coil degradation typically breaks the signal flow, which causes total accessory failure and leaves you stranded until fixed by a handy replacement part. - Heat cycling inside the engine bay damages internal components over many years of driving exposure - High current draw from auxiliary equipment stresses contacts until the relay can no longer carry voltage - Vibration loosens terminal connections while moisture ingress accelerates corrosion on metal pins
