I got the 140 fan regulator like you all suggested. Stripped the wires and hooked it up. Works perfect! Very easy to do, and save about $800.00!!!!

I called Phil up from Mercedesshop.com and he had the part to me in a day! I can't thank him enough. He is a great guy.

If any of you need parts...don't mess with a dealership. Just call Phil!

Thanks again to everyone that help!
