When selecting my blower fan knob, nothing is happening no air flow is coming in the cabin. Is there a fuse or relay for the blower fan?
Note: during the past week I could here a noise when the blower fan was working. Any suggestion?

Hello,

It sounds like the blower motor went out but to be sure lets run a simple test. Here is a guide to show you how to test the wiring and then replace the blower motor:

Here is the blower motor wiring diagrams and where the blower motor is.

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken

Yesterday I open the glove box and gave the blower motor a knock with my hand and it turn. Each time a gave a knock the speed changes. You think there is something inside obstructing the fan?

No it sounds like the fan motor is bad. Here is a link to a new one on Amazon for $47.00:
