Hi, My check engine light came on due to cooling fan speed low detection, and my fan doesn't cut on. But before buying the fan I was trying to check the relay for the fan or fuse for it but I can't seem to find either one and I've checked all three fuses boxes, but nothing seems to say anything about the fan at all so I'm stuck and would just like to get pointed in the right direction to get an answer please! Thank you!

There are 5 fuses that run the system with a cooling fan control module which is triggered by the BCM. Here are the cooling fan wiring diagrams so you can see which fuses to check and how the system works. I have also included how to change the cooling fan and the speed control module as well which is part of the cooling fan. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
