And Peter just in case you are still looking for the blower / Fan info
the part numer is A2028209342
I called my local Benz dealer and they wanted 380$
So as usual you dont go for the first price and you shop
around so I did and I found it for 105$ online.

Mercedes SLK230 SLK32 SLK320 W170 Heater Fan Blower Motor-Buy Car Parts At FCP
Its the same blower / Fan that goes in the MB SLK320 models
See ya and good luck let me know how it went!
PS. Model Says 98 - 2004 but thats only for the Benz vehicles the blower / Fan fits all crossfire models.
Hello benzFire. I have a 2005 LTD Coupe and having blower moter issues. I ordered and chaged the blower resistor which did not do the trick. I'm considering the blower motor now from the website you recommended. even though it says it is for 98-2004, you think it will fit the '05 Crossfire? Thanks!!
