What is the temp gage showing, in degrees? Is it overheating? Low speed fan won't come on till about 220.
Some systems, the fan will run if you unplug the cts. It also may turn on when ac is on. Any applicable trouble codes?

If it overheats, it will pop the radiator cap, where applicable, and the reservoir will fill up in a hurry. I looked at your owners manual, the temp gage goes to 260 degrees F. Give me a minute to look around.

In the diagram, the black wire at motors 1 and 2 are grounds. Fan 1, lite blue wire is voltage. Fan two, white wire is voltage. The ground for the coil side of relay/s is controlled by pcm. No ground, the relay won't energize.
