Why does my Suzuki Swifts AC cool only when the car is moving and not when idling?

In Karachi traffic, my 2014 Swift AC doesn’t cool at all when the car is idling o r stuck. As soon as I start moving, the air gets cooler. Is this a condenser fan issue, o r something to do with the gas pressure o r idle RPM?

This issue is very common in urban traffic in Karachi, Lahore, o r Islamabad, and can be caused by:

Faulty condenser fan – If the fan isn’t spinning properly at idle, the AC cant cool the gas, so warm air blows.

Low refrigerant pressure – Gas might only be effective when the compressor is spinning faster at higher RPMs.

Weak compressor – At idle, a weak compressor may not generate enough pressure.

Blocked condenser/radiator – Dust o r mud buildup blocks airflow.

Have a mechanic check the condenser fan function and clean the condenser. Also, a gas pressure test can confirm if refrigerant levels are low.
