c4 blower motor replacement

I need to replace the blower motor on my 89 C4. Can anyone point me to a link with step-by-step instructions, or provide instructions?

TIA.

I have a 92, and I wouldn't think that aspect would be too different.. I just removed lower rocker, so I couls remove the side grille, so I could remove the washer fluid bottle, so I could remove the blower motor... I did it in about 20 minutes while my girlfriend waited in the car... this is not a hard job
