What determines the duty cycle of the A/C compressor? - Toyota Yaris Forums

Exactly.

Ok fact is, even though the light is on that says the A/C is on, does NOT mean it is engaged 100% of the time.

It only turns the compressor on for a certain amount of time, then turns it off for a certain amount of time. Either that or it does so by temperature somehow, depending on where the knob is turned too.

So for everyone to understand this:
You are is losing 20%(on our stock engine) or so of power when the A/C ( the compressor ) is engaged! And just to clarify one more time for everyone, the compressor is NOT engaged 100% of the time, but it cycles on and off.

This should be the end of people giving out wrong information.

ozmdd is right as well (post above mine).
