how much time/money to change blowermotor '98 S320??
a friend of my mother in law needs it replaced and asked me if I can do it. I'm pretty handy with cars, when they are old though. anybody have experience with this model? tips? where to unscrew the plastic to get to it? how much for the blowermotor? (second hand ok)

It's easy to get to. I'd say an hour at the most, and that's at a relaxed pace. The link below shows how to change the cabin air filter. Once you expose the blower, you'll see what to remove to get it out. If your blower isn't rotating, make sure the fan shaft has not rusted/seized in it's bearing. Some people have gotten lucky by simply oiling up the shaft/bearing interface. They got their blowers to work again.

Are you sure the blower is bad?
You didn't mention why you think the blower itself is bad... these cars also are prone to fry the blower regulator, especially if the cabin filter isn't maintained/replaced at regular intervals. When you get the filter out, you'll see the regulator mounted right on top of the blower housing.
Before you go and buy a blower, make sure the regulator isn't the real culprit. If you call Phil at Mercedeshop, he can get you the blower motor by itself without the cage fan and housing. Good luck.

I agree with Ken P, WAY more times it's the regulator. Sometimes it's both, a bad motor can "take out" the regulator, but usually it's just the regulator. Replace the filter while you're in there.

thanks guys.
I have no idea, 'the blower motor needs to be replaced' is all the information I got. I looked at parts sites for that model and found the regulator on them and thought the same... blower motor without the rest is about $127, right? I'll try to go there and check it out for myself. is that regulator visibly damaged when broken? or would you have to have it tested?
