1997 Plymouth Voyager

My 1997 voyager has 150,000 miles on it with a 3.3 engine. My problem is the two coolant fans won't come on even when I turn on the a/c. When I connect direct power from the battery they work. They tell me that it's the rad. Coolant relay located behind the drivers side headlight, so I replaced it and the problem is still there. Auto zone says there are several things that tell those fans to come on.

The coolant temp sensor should tell the radiator fan when to run. With the a/c fan the PCM tells this when to run. The a/c fan should run as soon as you turn a/c on! Does the a/c run without the fan starting?
