Frequently asked questions
My car horn suddenly stopped working in Hyderabad — what should I check first?
Check the horn fuse first (easiest fix, costs ₹50). The fuse is usually in the engine bay fuse box — your owner's manual shows which fuse. If the fuse is fine, swap the horn relay. If both are fine, the horn unit itself may have corroded contacts (very common in Hyderabad's humidity). If the horn honks when you connect it directly to battery power but not through the steering wheel, the clock spring has failed. Metre Per Second diagnoses and repairs horn issues same-day.
