What are the reasons for the blower not working in the Nissan Sylphy Classic?
3 Answers
The reasons for the blower not working in the Nissan Sylphy Classic are as follows: 1. Prolonged usage: The blower has been used for a long time, leading to excessive dust accumulation, which increases the friction coefficient between the rotor and the bearing, causing the rotor to be obstructed or even stuck, resulting in overheating and damage to the coil. 2. Insufficient power supply: There may be no 220V AC input or the coil may be damaged. Turn on the power and carefully measure both ends of the power cord with a test pen. If one end lights up and the other does not, it indicates that the power input is normal, and the blower coil may be damaged. If the test pen shows both ends lighting up or neither lighting up, it indicates an issue with the power input.
Last time my car's blower suddenly stopped working, which was really frustrating. I specifically asked a mechanic about this, and there are several common reasons: First, it might be a blown fuse. The fuse for the blower circuit is usually located in the engine compartment or under the steering wheel fuse box, typically a 15-amp or 20-amp one. Second, the blower motor itself could be faulty. After all, this thing runs constantly, and worn carbon brushes or burnt coils are common issues. Third, pay attention to the resistor problem, as the resistor controlling the airflow is particularly prone to overheating and burning out, especially when set to maximum speed. Fourth, check for poor wiring connections, especially at the plugs where oxidation is common—look for any green rust. Finally, inspect the AC control panel switch, as poor contact at the terminals can also cause no response. It's recommended to try replacing the fuse first. If you can't fix it yourself, it's best to seek professional repair.
I've encountered the issue of the blower not working before, and it's indeed troublesome. First, check the fuse. Its location depends on your car model, either under the driver's seat or in the fuse box in the engine compartment. Look for the fuse labeled with a fan symbol, pull it out, and see if the filament is broken. If the fuse is intact, then consider the possibility of the blower motor being stuck or burnt out, as it's prone to failure after several years of use. Don't forget to test the resistor—the blower speed control resistor has a very high failure rate, often manifesting as no airflow at the highest setting or not working at all. Oxidized or loose wiring connectors can also cause poor contact, so try unplugging and replugging them a few times. The most troublesome issue is a faulty air conditioning control module, which requires professional equipment to diagnose. Be cautious when working with live circuits; it's recommended to disconnect the negative terminal of the battery before troubleshooting the wiring—safety first.
