Just replaced my Blower motor resistor. Very easy to do. Took about 1 hour. Found step by step instructions in this forum. Purchased Mercedes C CLK SLK Blower Regulator Fan AC Resistor NEW (#260768199607) from DeluxeChrome items - Get great deals on Replacement Car Parts, Chrome Auto Accessories items on eBay Stores! $79.95 delivered. I was having the same intermittent problem with my fan as most people have complained about. I have a 2005 Crossfire Roadster. Fan now blows perfectly. It's no longer available at that seller but this person has them: Mercedes C CLK SLK Blower Regulator Fan AC Resistor NEW | eBay
