Climate control issues are common due to extreme weather, dust, and lack of maintenance.

Common Causes:

Low refrigerant – Leaks in hoses, condensers, o r compressors reduce cooling efficiency.

Faulty compressor – Worn o r seized compressors fail to circulate refrigerant.

Clogged cabin filters – Dusty Pakistani roads block airflow, reducing AC performance.

Malfunctioning climate control module – Electrical faults o r damaged sensors affect temperature control.

What to Do:

Check and refill refrigerant if necessary repair any leaks.

Inspect and service the AC compressor and belts.

Replace o r clean cabin air filters regularly.

Test and repair climate control modules o r related sensors.
