radiator fan not working properly

[Patrick Anderson]

OK here is the deal. I just rebuilt the head on my car and replaced the radiator at the same time. Got it all back together but now my radiator fan doesn't seem to cycle on and off to keep things cool. The fan will come on when I turn on the A/C though. The fusible link is OK and so is fuse #15 in the fuse box under the hood. Anybody have any suggestions as to where to start on this problem? BTW, the thermoswitch ( I think that is what you call it) in the bottom passenger side of the radiator is only about a year old and is plugged in. ANY help or suggestion is appreciated.
