SOURCE: The cooling fans on a 1997 pontiac grand prix gt

This could be the fans not working or a bad temperature sensor. If you direct wire (hotwire) the fans and they operate then the problem is very likely your temperature sensor. The temperature sensor is usually located on or near the thermostat housing. I hope this helps.

1999 grand prix gtp second cooling fan will not turn on

How hot is the vehicle running? The second cooling fan is programmed to operate only, like the first cooling fan, at a predetermined engine temperature. It varies by model, if I remember correctly however I think it is 226F for the fan to turn on, and at some point if that does not begin working the second fan will turn on.

The problem is my radiator fan wont come on

There are 3 possibilties that can cause your problem.
1. The thermoswitch that is mounted in the radiator that activates the fan when a high temp is received. It will look like this:
