Radiotar Fan Hi/lo function

[dpok69]

How does the hi/lo speed function of the radiator work?

My fan only turns on high if my ac turns on or if i ground a wire on a relay on the drivers side. Otherwise it stays low all the time.

Is this normal? My car sees temp in the 190's on hot days.

Not 100% certain, but here goes:

Low speed - controlled by chip, some start at 170 (stock 195 ??)
High speed - controlled by AC OR if temp goes to 210 (??) OR your manual switch.

Prolly close.
