99 cv interceptor. cooling fan comes on after indeterminate amount of time. will not shut off until car is shut off. immediate restarting and fan isnt running. a/c is off, engine temp is mid scale. tried switching fan relay in relay box with one of the other three to no avail. anyone have good schematic to post on this? also could temp bulb(where is it?) cause this. didnt try swapping the smaller 30 A relay as I had no spare. Ideas welcome please!
