Hello from South Carolina/Help with Cabin Air Filter needed.

Hey all! Joined cause we bought a 2010 Aveo LT and am having trouble with replacing the cabin air filter. I went online and have seen some videos all showing the same place for the CAF, but on ours the CAF cover that easily comes off on the video does not exist, the housing itself is solid, 3 screws that separate the upper and lower parts of the housing,,,wondering if anyone else has the same type. There is another screw to the left of the bottom part of the cover that connects to the firewall, really didn't feel comfortable to continue and mess something up. Any suggestions?? thanks.

Can you post a picture? If it doesn't have the panel, you may not have a cabin air filter.
