Matt L I am out of town for a few more days so I have not had a chance to check the location, anyhow I did look at a couple online parts and could not find a control module for my 98 E320. I was just going to go ahead and buy one if not to expensive. Do you think a straight 12v to the fan could exonerate the fan if works freely? Also beside dealer any suggestion where I can purchase control module. It is easier to find it if I know what i am looking for. Thanks for the help.
