Post subject: A/C Halp

Ok so my A/C is acting funky and I think I have a few ideas as to what it might be...

So it is fully charged and blows cold air BUT:

It stopped blowing any air at all on settings/speeds 1-3, however it still blows at the proper speed for setting 4 (highest).

This leads me to believe it could be the a temperature regulator or some type of relay/module. I know on the fourth setting highest speed these are bypassed, so that's why I think it's something like that. However I do not know exactly the parts names for those pieces, which ones my car has, and if those would actually be the cause. I think it could also be just the switch (it's somewhat loose and pops out of speed at times) so it could not be triggering the action.

Does anyone have any ideas as to what this problem could be coming from, or know the exact names and parts I need to try and switch out to fix this.

Here are a couple links for possible parts.
