I've put in a new fan thermostatic switch. I shorted the thermo switch wire
with the ignition on and the fan comes on, so the fan is working. The fan will
not come on with the temp gauge well in the red zone, engine running.
I tested the old and new fan switches on the stove in antifreeze and both
come on at about 220 F, off about 180 F. I know the fan wires, one is blue
is hot when ignition is on, the therostatic switch supplies the ground to the fan,
a black wire. It acts as if there isn't a good contact of the switch prongs
and wire sockets, but I did test the wire sockets by shorting and fan came
on, ignition switch on, I already said that.
Any help appreciated.
