fan switch location

hello, on a 1983 where is the rad fan switch located? thanks

The radiatior fan switch is in the lower drivers side of the radiatior. It is a thermo activated switch, when the water gets hot enough the contacts close and the fan comes on. The fan has constant power to it via the blue wire. The ground wire is interupted by the switch. If you trace the black wire it will go from the fan to the switch then out the other side of the switch and to the "bottle cap" ground pod on the drivers side fender.

Thanks Matt, so I guess I'll be draining my rad after all
