Blower motor screen for A/C 2008 Tahoe LTZ

[sunndancekiid]

I just installed new blower motor for AC and i noticed that there is a screen above the blower that catches trash such as pine straw. Is there any way to clean pine straw from this screen. I dont see any type of access to this area unless it under passenger side dash or thru glove box. Any suggestions or instructions would be appreciated.
