Hello all! My 1979 450sel, euro model, with only 64,000 miles seems to have an issue with the aux fan. The #2 fuse continues to blow [protects only the fan], and teh fan never seems to come on - even when I try to jump it [connecting the single pole coolant temp sensor lead to ground so cause the fan to run]. Any ideas? Your advise or experience is appreciated....dpeszek@gmail.com
