Why does my engine stall when I turn on the AC?
Like many parts of your vehicle, the air conditioning system takes its power from the engine. If not working properly, the engine may not cope with the loads produced by various systems in the car. More specifically, it may be too low to run the A/C and hence it stalls when turned on.

A seized AC compressor can stall your engine when you turn on the air or defroster because it sends a signal to engage the clutch on the compressor, which causes more resistance than normal.

How do you tell if an AC compressor is bad in a car?
Why does my car shut off when I have my AC on and I am at a complete stop?
When the AC is turned ON, the valve opens to flow more air into the engine, increases Its Idle RPM, and also produces more power and vice versa. So, when carbon builds on “Idle Air Control Valve (IAC)”, it will fail to maintain proper idle, and as a result, the car surges and shuts OFF when the load is put.
