Need Help 2009 Ford Edge cooling fans trouble.
 

Need help with cooling fans on my 2009 Ford Edge. We have replaced the cooling fans due to the original fans not working. We have purchased two new sets of cooling fans assemblies and they want work. But if we put the old module on the fans they run slow with the ac switch on. If the compressor comes on the fans stop. The fan on passenger side runs fast if the other one is unplugged from the wiring harness. I need help. Does the module have to be programed for this car or should the assembly work automatically?
