Jumper the high-pressure switch on the A/C dryer and they should come on low speed, if not then there is a ceramic resistor nearby that often fails.
Check also to be sure that they turn freely. It sounds like they might be freewheeling from the airflow when you're revving the engine.

When I jump the temp switch on the top of the engine the fans run. When I jump the temp switch on the A/C dryer the fans do not turn on. I can hear the relay under the fuse panel closing but the fans to not work.
Where is the ceramic resistor you are referring to? How do I test it?
Thanks
