I just replaced my cabin filter in my 2002 Seville STS. I've read the other posts and this job is no picnic but I have some suggestions.
1) Remove the new filters from the package and note that that don't slide together that easily even when new. Obviously, after being in your car for many years (10 years in my case) they probably won't slide at all. You are supposed to be able to pull on the bottom tab sliding the bottom filter out and then the second filter drops down and you pull that one out and the third filter drops down and you remove it. The reality is that probably the plastic has welded together and nothing will slide. No shortcuts; just get them out however.
2) Now we can make some improvements. The factory service manual suggests using silicon spray on the new filters to aid installation. Instead, use silicon paste or grease. The filters will slide together MUCH easier than with the spray and because Silicon grease never deteriorates, the next time the cabin filter is changed each section WILL slide out just like the factory manual says it should.
