Could electrical o r sensor faults be causing the AC system in Changan Kalam to stop blowing cold air?

If AC control modules, temperature sensors, o r relays fail, cooling can stop. Are such issues being checked in local diagnostics?

Yes, absolutely:

Faulty temperature sensors inside cabin o r evaporator can cause the system to cut off cooling early.

Relay o r fuse issues may prevent compressor clutch engagement.

Software glitches in AC control modules are sometimes ignored entirely in diagnosis.

Pakistani workshops usually don’t check these unless requested specifically.
