In my 2003, I never had to remove the glovebox door to change the filter, I just opened the glovebox all the way and would shine a flashlight in there to see the filter access. It's really easy to remove and install. It takes about a minute from start to finish. A few times, I'd turn on the HVAC system and have the fan blowing at full speed as I sprayed some Lysol into the cabin filter housing prior to inserting the new filter. Helps to keep down any musty smells. I used to change that filter every year.
