Hello,

That knocking noise is probably a blend door actuator that has gone out and needs to be replaced. Here is a guide that will help you see what I am taking about with a diagram (below) that will show you what it like on your car.

Please let us know what happens, we are interested to see what it is.

Cheers, Ken
