electromagnetic fan not switching ON

I've checked and replace the fuse I've also replace my temp sensor, only the electric fan switches on at about 105'.
NO main fan switching ON at about 100' how it used to.
What could be the problem? and how do I check to see if my fan clutch has stop working and or is there a temp sensor or switch for the electro fan itself?

"your responses would be aprreciated"

For the main electromagnetic big fan there is a red temp sensor on the top of the engine. It may be grey. It has two or three prongs. Jump the connector to see if the fan kicks in if it does replace the sensor.

I've jump the connectors, but only the electric fan kicks in and not the main electromagnet fan.
Is this suppose to happen or is the main fan use another sensor?

What he said ^^

That switch controls the aux fan AND the clutch fan. I think its the two close together for the clutch. Whichever two you jumped to get the aux fan going jump the other one.

Yes- I've allready jumped 1 and 2 sockets and only the electric fan comes on.
I've also turned the car on and let it get hot and only the electric fan turns on at about 105-110', but NO motor fan....
How do I check to see if my clutch has gone bad--"if thats the problem".

Thanks for your replies guys...

My guess would be to feed 12v directly to the connector just behind the fan to see if the magnet engages. But you would have to be extremely careful that fan can slice of your arm.
