Ford Windstar: problem with my cooling fans..fuses under hood

Customer Question

Ford Windstar 1995 . I'm having a problem with my cooling fans. I checked the fuses under hood . They all look good . The connections to the fans wires are secure . Wires look good going into wire harness then I lose sight of where it's going. Heard this was a common problem with this van and an easy fix . What is the easy fix? Is there any controlling fuse in main fuse panel inside van I need to check or a sensor? Please help. Main Problem fans not coming on at all . Update I unhooked the sensor and the fans kicked on. Can I leave the sensor off till I get the new part?

The most common problem with these is a failure in the CCRM(constant control relay module) located near the battery under the hood.There is also a voltage dropping resistor that can also go bad located near the right side engine compartment.

Where would I find the CCRM to make sure it is plugged in right and what does it look like?
Expert:  Scottdagoalie replied 7 years ago.
it is a 3X4 metal box located near the battery and above the cooling fan,

with about 20 wires going into the top of it? It almost looks like a over sized Relay? Also when I turn my air conditioning on the fans works . they go on and off but if I turn the air off the fans do not work at all and the van starts to get up too 230 .

Yes,that is it.unplug the coolant temp sensor to see if the fan comes on.It may have a PCM issue.
Customer: replied 7 years ago.
sorry it has taken so long to get back . Power has been out due to a really bad storm. PCM issue?
Expert:  Scottdagoalie replied 7 years ago.
The PCM receives a signal from the temp sensor and sends a fan operation signal to the CCRM.Unplug the temp sensor to see if the fan comes on .if it does,the pcm is ok and the sensor will need to be replaced.

Sorry last question . I unhooked the Temp sensor and the fans came on so I have a new module coming. Can I leave the temp sensor unhooked to keep the fan on or will it hurt something ?
Expert:  Scottdagoalie replied 7 years ago.
If the fan came on when you unplugged the temp sensor,you need to replace the temp sensor.
