Heater/AC fan not blowing air

So i have a 2002 Xterra SE SC 4X4 the heater/ac fan is not blowing any air. This started about a year ago with it blowing 90% of the time then slowly over time not working at all. When the heat is on, it does get hot and the a/c it gets cold but there is no air actually blowing. I do take my rig into the woods and there is a good possibility that something is loose, just not sure where to start?? I have checked 2 fuses inside the car 15 amp listed as blower, and those are fine. Not sure of any other fuses i may have missed??

I have replaced the Blower Motor and still does not work, so figured i would try the resistor since its a cheap part. Still does not work.

**ALSO, when the car is running and i have it set to HEAT, and change from 1-4 speed you can hear the motor change like when you turn the A/C on, however it never blows cold air.. It's as if its drawing power when i turn those switches, not sure if its supposed to do this or if it did this previously and i never noticed??

So i decided to test the Blower Motor connector to see if there was any power going to the motor and there is not. Does this mean my climate control switch is out?? I went to a wrecking yard and picked up a used switch for $56.00, it has the cables attached to it as well, looks a little intimidating to take the old one out of my car.

I'm not super knowledgeable about electrical stuff, so if anyone has any input before I try replacing the climate switch, I would really appreciate it! Also, there are no videos on YouTube to take that part out, does anyone have a thread to guide me or videos?? I have a feeling the whole dash has to come out, and it may be a pain...?

I was really hoping it was the blower motor, such an easy part to replace and seems to be a very common issue.

Did you ever figure out your problem?

My '08 just had this happen. Replaced resistor and blower, nothing. Parts take a bit to get to the north, and cold snap is about to hit again
