Can i put a blower motor setup from a different honda (civic/accord) into my 88 crx si?

So. Its winter time again and. I have a 88crx si that has a blower motor speed switch thats out and i Can't find one for my life. No junk yards, and honda discontinued that part.

so my question is could i get a whole brand new blower motor setup and install it into my car say from like a 92 honda civic.

could i get that to work in my crx?
