When I turn ignition to on position without turning on engine, I can hear a weird sound from back seat on passenger side. It's like a mouse scratching or biting wood board. Turn off the key then the sound disappears. It's almost like above the right rear wheel. I dont think this is from air compressor because I can hear the buzzing sound from it. Also I changed the two rear air shocks and so the sound is not from the air shock either.

Anyone has the same sound or something is going wrong with the truck?

You may be hearing the blower motor. The rear HVAC is at the back passenger side of the vehicle. See if turning off the HVAC changes the noise.

I will check it later. Thank you!
