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.

How to Start as a Used Car Broker for Beginners?

You need to be able to identify whether it's an accident-involved vehicle, as such cars are tricky in the current market—handling them poorly could lead to losses. At the very least, you should be able to inspect the car's condition by looking, smelling, and listening. Sellers will naturally first inquire about the price of their car from the broker. At this point, the broker should absolutely avoid rushing to lower the price.

How to Drive on a Highway with Only 2 Lanes?

Before entering the highway, the car owner must go to a repair shop or 4S store to check whether the vehicle's condition is normal and whether the tire pressure is normal. The speed should not be too fast, but also not too slow, because there are maximum and minimum speed limits on the highway, and you cannot change lanes back and forth. You cannot always drive on the left side, because the left lane is for overtaking and cannot be used continuously; it should only be used when overtaking.

Where is the Altima air-fuel ratio sensor 1b1 located?

The Altima air-fuel ratio sensor 1b1 is located above the three-way catalytic converter, with the V6 engine B1 air-fuel ratio sensor positioned on the left side. Since the three-way catalyst's purification capacity for CO, HC, and NOx drops sharply once the air-fuel ratio of the mixture deviates from the theoretical value, an oxygen sensor is installed in the exhaust pipe to detect the oxygen concentration in the exhaust. It then sends feedback signals to the ECU, which in turn adjusts the fuel injection volume from the injectors, thereby maintaining the air-fuel ratio of the mixture near the theoretical value.
