MikeR thanks for the info , I guess when my AC turns off and back on every 5 - 20 minutes now I know what part to replace and where to locate the resistor. (I Heard its about 65$ and easy to replace)


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.

link is here.
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.
