[s-cars] electric cooling fan operation

[chris chambers]

Sir. Bill Mahoney has had some experience with this issue, I am sure he can provide in  depth details on what to check.
As I recall the causes could be: Bad temp sensor and/or fan, plus there is a large fuse.
Several of us were involved in the diagnosis and repair of this issue at a previous //S-Fest
 
 
Bill .... feel like sharing?
