What is the reason for the hazard lights not working while the turn signals are functioning normally?

The hazard lights not working while the turn signals are functioning normally could be due to a blown fuse or a burnt-out bulb. Below are the relevant explanations: 1. Car Fuse: There are many electrical devices in a car's circuit connected by wires of different colors, among which the most important should be the fuse. The fuse is a customary term, referred to as a circuit breaker in national standards. The role of the fuse is to protect the circuit (wiring) and electrical equipment. 2. Bulb: Try turning on the hazard light switch to see if the lights come on. If they do, the problem lies in the turn signal switch part. If they don't, check if all four turn signals are not working. If the issue is with the bulbs, it is generally unlikely that all four bulbs (front, rear, left, right) would fail simultaneously.
Last time my car also had the issue where the hazard lights wouldn't work, though the turn signals were functioning normally. It turned out to be a blown fuse. The hazard lights and turn signals share the same bulbs, but their circuits are separate. The hazard lights are mainly controlled by the flasher relay, which is hidden under the steering wheel or in the fuse box. You can start by tapping the hazard light switch a couple of times—sometimes poor contact can suddenly fix itself. If that doesn’t work, check the 15A fuse labeled 'Hazard Warning Lights' in the fuse box; pull it out and see if the metal wire inside is broken. Next, inspect the hazard light switch itself—oxidized contacts can also cause poor connection. The worst-case scenario is a faulty body control module, which requires a computer diagnostic. I strongly recommend fixing the hazard lights ASAP—driving without them in rain or fog is extremely dangerous.
