2003 Boxster AC/Heat won't work

I have a 2003 Boxster and it won't blow anything from any of the vents. I understand it may be the blower resistor or even the blower itself.
One note that may or may not be related, if i hit the AC button, it won't even turn on. I expected it to at least show the AC was on and potentially draw the engine down a little but it is like it doesn't engage.
Also, I know the parts for the blower are up under the passenger side dash but I can't find any good references on replacing it on my model. I could just be overlooking them.
I would appreciate any and all help!

Thanks

You mention zero about fuses. You did check those, correct?

Fuses was the 1st thing I checked. I knew I wouldn’t be that lucky.

And no chance someone has been behind that switch panel recently or even in the past since the factory?

Not since I bought it for sure. Can’t speak to before that.

Resistor.
It will keep the snowflake from showing, too.

Does anyone have a video or pics of how to get to that resistor? I have looked up under the dash and it doesn't appear very easy to get the resistor out.

One last thing. Could this also be caused from my ignition. It started giving me some issues a while back where the key wouldn't come out and such. I have a replacement on order but read today that it can cause some weird electrical issues as well.
