Engine electric fan running at low speed when compressor engaging.
I just bought a Toyota Echo 1.5L 2004. As far as I know the engine RPM will slightly increase when the air condition compressor engage. But my car not. The RPM only increase when the electric fan running at full speed and the compressor engaging. Just want to know if my freon pressure is normal or not. Either too much or too low.
