How do you replace the windshield wiper motor on a 984 porsche 944?

I was driving it this weekend and it just died on me. I replaced the battery two days ago and the wipers would move up then stop at the bottom if assisted (now they don't move at all). I can see/hear my axel in there spinning, so i don't know if it is the motor itself (although it sounds like it), or if i'ts a slippd belt.



Do I have to go into my firewall to get at them?



Can't find any examples or directions on how to do it myself.How do you replace the windshield wiper motor on a 984 porsche 944?
