Alternative way to access the cabin filter on Kia Sedona?

What is your question?

I'm pretty sure I have a mouse nest somewhere in my air ducts. Smells like a wet barn when the heat, AC, or defrost is on and it's pretty bad. Sometimes there is a roaring, "thwapping" sound when the blower is on. It sounds like debris is caught in the fan, but the noise is not consistent. I have a person lift installed on the passenger side for my disabled son, and it blocks access to the cabin filter. The glove box only opens halfway with the lift installed, so there's no dropping the cover to access the cabin filter. The only solution I can find is to take the Sedona back to the mobility company that installed the lift, have them uninstall it, change the filter, and re-install it again, to the tune of about $700. Please tell me there's another way! Thanks for any suggestions you can offer.
