I’ve noticed when I switch my fan on it is noisy and sounds like something is in the fan. Have a feeling unwanted guests may have made a home. How do I clean the fan out or should I say how do I remove the fan/housing? Is there a link to an old post perhaps?

You can get it out without pulling the dash, but its a lot easier to pull it.
I've removed the fan assembly on my '87 a few times without issue. Not that bad.
Impossible to do on my '85. But it was wrecked before I got so I assume the body was warped.
