Why does my engine stall when I turn on AC?
Why is my car stalling when I turn the A/C on? Like many parts of your vehicle, the air conditioning system takes its power from the engine. It’s understandable that due to this, there may be significant pressure on the engine. More specifically, it may be too low to run the A/C and hence it stalls when turned on.
Why does my car want to die when I turn the AC on?
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.
Why does my car die when the AC is not on?
When the AC is not on, there is no resistance being put onto the belts by the compressor. When you turn the AC on, it creates friction to run the compressor. This makes your alternator and belt/pull system work harder. If you are able to, check to see what your alternator is putting out for voltage using a voltmeter.
What to do when your AC is on in a Toyota?
Open the throttle blade carefully. Clean the throttle blade and the surrounding bore. Do not scrub, let the solvent do the work, no scratches are allowed on the polished bore. After cleaning start the engine and let it idle for at least 20 minutes while the system learns it’s new throttle position. This vehicle should relearn on its own.

Why does my engine stall every time I Turn on the AC?
Your a/c compressor is binding up and the pully wheel isn’t turning. When the belt is stopped it puts a huge strain on your motor marking it stall. Get your ac checked out. It’s likely a bad compressor and not likely any wrong with the engine. Some loading is normal but your PCM will adjust accordingly.
