The radiator fan relay may be located behind the left headlamp assembly. You'll have to pull the assembly and find it under a plastic shield.
Inspect connector and wiring harness
Check Fan motor

Start by replacing your thermostat. I suspect that your thermostat is stuck open. It will heat up just fine at idle, as not much coolant movement from the water pump. But as the engine runs at higher rpm, your water pump moves coolant throughout the engine; with the thermostat sticking open, the engine doesn't have enough time to keep the coolant warm.

How do I know if its the thermostat or the water pump not working. My engine is good on all fluids but the van overheats in about 8 minutes when driving it and the anti-freeze level does not go down at all. Im not a mechanic but wouldn't it be the water pump not semding the fluid to the cooloing system?

There is coolant leaking inside of the van. Where is this coming from? It has gotten so bad my husband started putting water directly into the radiator. On multiple occassions. Stating that it wouldn't hurt anything. Is this true?

Failed heater core will leak coolant inside and fog the windshield when defrost is on

add water is not recommended in cold climate as water will freeze causing an engine and coolant system damage
after the leak repaired make sure coolant system flushed and coolant added to system
good luck

Check coolant level and thermostat.

You may have damaged the head gasket from driving overheated

My vans fan wouldnt shut off so I disconnected the battery. Then I reconnected the battery, the fans started to come back on the I heard a click and they shut off and now they wont come back on even if the motor is hot? The fuse under the hood is good is there another fuse?

Overheating occurs at idle or very low speeds I've replaced water pump, temp sensor, antifreeze. Radiator fans cycle once gauge pegs out and warning beeper comes on. Engine cools down if you start driving about 40 mph and never heats up again until you start driving 20 or less for 10 min or so

Yes, I was not able to edit my question to include that, but I'm thinking maybe a radiator/engine flush is the only thing left that I can do cheaply, and possibly install an adjustable radiator fan control and run the fans at a lower temp than the factory setting.

It sound like a circulation problem. So if you haven't fixed it yet I would do a chemical test to make sure there isn't a bigger problem and have them unless you can check the temp difference between the upper and lower radiator hose.
