Does the AC performance in Changan Kalam significantly when the car is idling o r in traffic jams in Pakistan?

Many users report weak cooling when stuck in traffic. Is the radiator fan o r idle AC compressor performance to blame?

Yes — this is a known issue:

Weak radiator and condenser fans at idle speed lead to heat buildup, which reduces AC performance.

Poor compressor output at low RPMs is common in budget cars like Kalam.

AC is much stronger while cruising, but weak when stuck in traffic, especially with high cabin load o r under sunlight.

Solution: Ensure fan motor health, clean condenser, and correct gas pressure.
