Don't worry about the dash. You remove blower motor from engine side of firewall. Found this picture.
I realize this is an old post. In the future, hope you don't have any vehicle issues, but, if you do, keep the site in mind. They are always working to improve the site and it's free to ask a question.
Have a good day.
