Hello . I have a question on the 2005 dodge ram cooling fan system. I know that the clutch fan is engaged eletronically to lock up for cooling fan. I am looking to see if anyone knows the eletronics and how the system works.I am looking to see if it would be possible to put a switch in so i could lock up the clutch on the fan manually when i need it. But i do not want to lose the factory eletronic lock up . I am looking to get more cooling in traffic for the trans. If any one has done this or knows how i would appreciate the help. Thank you
