2011 Nissan Sentra AC/Heating Malfunctioning

Asked by Jan 03, 2017 at 12:14 PM about the 2012 Nissan Sentra 2.0 S

Question type: Maintenance & Repair

I've been having some issues with my car recently...anytime I turned the
air/heat on there would be this awful almost "knocking" noise but when I
turned it off it would stop. Well I was demonstrating to my mother what it
was doing and suddenly the noise stopped but now I can't turn the air off.
All the other controls work (temp, etc.) but I can't change the air speed.
Even with the dial on "OFF" it still blows at high speed as well as the
knocking sound has returned. The air and knocking sounds stop when I
turn the car off.

I guess I would take out the blower motor and see if there are any obstructions against the squirrel cage. The blower motor speed thing is more than likely a blower motor resistor.
