LNF fans run all the time when engine is running. Schematic says fuse #7 and shop manual says #40???.

Its not a fuse. There is only 1 fuse for the fans and its the one I have to keep pulling to get them to stop.

Somebody said something about the map sensor. It does have a blown upper map sensor... but it has been this way for a few weeks and just now started having this problem. Also, I dont see how the map could cause this to happen...
