Afterrun Cooling

I just did my radiator and before pulling it I trouble shot the afterrun
system as it did
not seem to come on when I would expect it. I also jumped the temp
switch to get it to run,
I replaced the switch while I had the radiator out( much easier ). I
tried letting the car idle until
 the fan comes on, then turning the car off to see if the afterrun pump
will come on in a bit, no luck.
I will watch it when it gets warmer. I live Nor. Calif. and we do not
get as cold as most of the listers.
