Hi hope someone could help. i just noticed today that my rear humidifier doesnt work. sorry dont know whats it called. its the button at the right side of "Auto" for the A/C. The button lits up but i dont hear any sound that it was working at the back, im supposed to hear a blower sound like when its turned on. The only thing i hear is a click sound when i turn it on, and i can hear a click or tick sound on the fuse part under the steering wheel.
