It's All About the Build
Have any of you had issues with your cooling fan not functioning correctly – to be more specific, the low speed fan not working?
I’m not absolutely sure, but I think the low speed fan is not coming on. When the fan finally does come on, it seems to come on at about the same speed (volume of air) as when the A/C is on, which is only the high speed fan. That is what leads me to believe the low speed fan is not working. I do not have an overheating issue nor have I datalogged the fans.
I looked at the wiring schematic for the cooling fans and it seems fairly simple. There are a couple of fuses, low and high speed relays and the fan motor. The relays are controlled by the PCM.
I also know that Ford has changed the part number on the fan/shroud assembly since 2005. The new part number is 7R3Z-8C607-A.
