IT sounds like it is operating normal. The primary fan will handle the heat and keep it in check, ( I assume you aren't overheating). The secondary fan comes on if the Primary fan can not adequetly prevent overheating temps of if the the A/C is on as the a/c is heavy on the system.

There is two gray plug's on the right side of the rad. The lower plug when you pull apart it will work the fan's. They will stay on when you turn the car on and off when car is off. But when I plug back up and car is hot cool down fan will not come on.

Sorry, I assumed fuses were checked.

I doubt it is a fuse issue based on unplugging them changes the operation. The circuit that the plug is on is causing a problem is my thought.

That was what I was thinking reading through.
This may help. The sensor may be giving false data and not turning on the fan.
