No position matches. Try one word — “headlight”, “pump”, “window”.

Fuse colours follow the blade-fuse standard (DIN 72581-3 / SAE J1284) and are derived from the rating. The number is what counts — older torpedo fuses use a different colour scheme. Cross-check the lid of the box.

Fuse keeps blowing?

A blown fuse is a symptom, not the cause. Tell TorqFix which position it is and what the car does.

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

Variants of the same model differ. Check the year and the label on the box in your car before pulling a fuse.

Seen a figure that does not match your manual? Write to us — we correct it and note when. support@torqfix.com
