Took the housing off, and then I was unable to get the broken bolt and take it out - easy breezy.
So, it's all put back together, and the problem hasn't changed any. Burped it using one of those funnel things as my G doesn't have a burp plug in the back.
Low speed fan comes on at about 206* with the AC off. I turned the AC on, and low and behold the fans turned on high!
Take it for a test drive, and it heats up to 219*, with the AC on. I pull over to the side of the road, and the fans are low, I hear that the fans are running low, and trying to spin up fast.. I can hear the fans RPM increasing, then dropping back down, never getting to high-speed and it repeats the cycle constantly. It knows it needs to speed up the fans, but it just isn't doing it.
I already replaced the control fan module - twice, once in March, and just now. I previously tested the fans directly with 12V, and they both spinned up on high with no problem.
If the sensor is reading temps out at 180, 200, 210, 219, I don't think it would be the temperature sensor.
