Hi guys, can't really comprehend the issue on my MDX 2004.
If i put the Car in "ON POSITION" (not on ignition) where i can operate the radio, CD and the likes. If i on the AC pressing the auto, it only blow air meaning only the fan works. But as soon as i turn the ignition ON, the AC start getting cold, is like the compressor doesn't pick until the car engine is running, that is putting the vehicle in ignition mode. Once i turn the ignition off and the car is running on battery, its start blowing air alone.
This affect both the front and the rear AC, in addition to this problem, the rear AC never shut off using the Rear Manual button, it comes up immediately once i put the car on. When i press the Rear button, the control shows light and also control the rear AC as expected which means their seems to be communication but the rear manual button would not turn off or turn it on, it comes up as soon as the car is on, on battery.
