💡 Why does a window defroster relay fail prematurely in older vehicles?

Electrical fatigue usually stems from poor heat dissipation inside worn housing units.
- Watch for corroded pins that disrupt steady current paths during cold starts
- Check how often the system cycles to prevent overheating on extended drives
- Keep connectors clean to maintain low resistance and sharp switching signals
- Swap outdated units with a handy direct fit part for lasting peace of mind
