10 solucionesReplace Fuel Filter
Replace the fuel filter to ensure clean fuel is reaching the engine and sending unit.
Drain and Clean Fuel Tank
If fuel contamination is suspected, drain the fuel tank and clean out any sediment or debris.
Replace Instrument Cluster
If the fuel gauge is determined to be the faulty component, the entire instrument cluster may need to be replaced.
Test Fuel Gauge
Perform diagnostic tests on the instrument cluster to verify the functionality of the fuel gauge. This may involve applying known voltage signals.
Repair or Replace Wiring
Repair any damaged sections of the wiring or replace the affected harness if necessary.
Check Wiring Harness
Inspect the wiring harness connected to the fuel sending unit and the instrument cluster for any breaks, corrosion, or loose connections.
Replace Fuel Sending Unit
If the sending unit is found to be faulty, replace it with a new, compatible unit.
Inspect Fuel Sending Unit
Access the fuel tank and visually inspect the fuel sending unit for any signs of damage or corrosion. Test its resistance values.
Professional Fuel Injector Cleaning
Have the fuel injectors professionally cleaned and tested for optimal performance.
Use Fuel Injector Cleaner
Add a quality fuel injector cleaner to the fuel tank to help dissolve deposits.

Causas Identificadas
Low Refrigerant Level
90%The AC system relies on a specific amount of refrigerant to cool the air. A leak in the system can cause the refrigerant level to drop, leading to insufficient cooling.
Faulty AC Compressor
70%The compressor is the heart of the AC system, responsible for circulating the refrigerant. If it fails, the refrigerant won't move, and no cooling will occur.
Clogged Cabin Air Filter
50%While a clogged cabin air filter primarily affects airflow volume, in severe cases, it can restrict airflow enough to impact the efficiency of the cooling process, making the air feel less cold.
Electrical Issues
40%Problems with fuses, relays, or wiring within the AC system can prevent components like the compressor or fans from operating correctly, even if the fan motor itself is working.
