Before you will start this replacement take the vehicle to the service mechanic garage and evacuate all freon, when the replacement of the condenser and compressor is done pull the full vacuum and only then add freon. Also, it's better to evacuate the power steering fluid and completely disconnect the power steering otherwise it will be always on your way when you will be removing and installing the new compressor.
If installing chip an aftermarket compressor is not made in Japan, not Denso or not some other genuine brands... you also will need to swap the clutch lock sensor from your old compressor and install it on your new, not original compressor replacement, it's responsible for shutting the compressor off at very low RPMs and if clutch lock sensor, on your new compressor, not original japan made or bad most likely you will get AC blinking light if the engine RPM will be under 1000.
