Q: How to fix A/C works intermittently or cuts out during driving in Ford ECOSPORT?

The car stalls unexpectedly when braking, especially when the air conditioning compressor is turned on, which generates a large load on the small capacity unit. Solution (as per TSB 21-2422 and campaigns for BS6 models): Perform engine control unit (PCM) software update. The new software re-calibrates the thresholds and cut-out moments of the air conditioning compressor clutch so that the engine does not choke under heavy load in the cooling system at low speeds.
