So, it seems that it sometimes is cold air mixed with hot air blowing from fee, defrosters, but not the face vents and it switches to recirculate air but the front vents with the arrow pointed at the face is not switching. I need to know the location of all fuses and relays under his and in cabin are located, please.

The fuses are probably okay but here is a guide to help test them:

Here are the fuse locations with the relays, but to me it sounds like the Mode blend door actuator stopped working which is common.

Check out the images (below). Please let us know how it goes.
