Radiator fan wont turn on

Hey guys,
I have an 05 mustang gt, auto, 94k miles. The car overheated a couple of days ago and ive been tryin to figure out whats wrong with it.
I noticed the radiator fan was not on when it overheated and it doesnt come on. Checked fuse 40a and it did look slightly different than all the other fuses on there so i replaced it and so far the fan has not turned on still. I pulled the fan and it looks like the original ford fan, tried jumping it from the battery and it didnt start but I only hooked up 2 out of the 3 prongs that are on the connector.
Anybody that had this problem before and could chime in or anyone with knowledge on stuff like this that could help me out, it will be greatly appreciated!

First I'd check to see if there is battery voltage going to the fans, check and see if it has a ground. There could be a short in the wiring.

Another possibility is the fan motors are bad.

Do the cooling fans come on when the air conditioning is turned on?

How hot did the engine get and how far did you drive it like that.

Cooling fans do not come on when ac is on max, it was a short trip i was driving it for about 20-30 minutes before i realized the needle was close to the H on the meter on the dash. Once i saw that i pulled over and shut it off and let it cool a little. I drove it a block down after 10 minutes to park it.

20-30 min of highway driving or city,stop and go? Were you stopped when you noticed it started to over heat is what I guess I should ask

What I suggest is take it to your trusted auto tech or a ford dealer. They should have the proper tools to run diagnostics to make sure the engine is damaged

You said the 40 amp fuse looked different. Was it blown? If so, check it again and see if it is blown again.
The two most likely suspects are the fans (or fan), or the Constant Control Relay Module.

The 40a fuse was a different color (copperish) and it looked like it had ridges. Will check the new fuse

A blown fuse could look identical to a healthy fuse.

Oh. Ok.
They come in different colors depending on the amperage rating of the fuse.
You notice that they are transparent and you can see the metal part that runs continuously through the fuse to both of the prongs. In the center of the fuse, it is thinner metal and that is the part that melts when the amperage exceeds the fuses maximum amperage rating. The metal part will be separated at that thin part and that is what is commonly referred to as a blown fuse.

And Recon is correct. It can be sometimes difficult to tell if a fuse is blown or not. But since you replaced it with a known good fuse, you should make sure that it didn't blow the new one again, which can happen. If the fuses are continually blowing, it's almost certainly a defective fan. If not, it may be the CCRM but I would have someone knowledgeable diagnose it before throwing unnecessary parts at it.

Fuse looks complete, aside from some discoloration

I think so. Just don't let it warm up. Start the engine and go. Keep an eye on the temp.

I had to drive my car ten miles one time with only about a half gallon of water in the radiator!
Good luck and keep us posted on what you find is wrong.

Post a pic of the fuse if you want. We'll try to determine if it is blown or not.

My 2010 GT overheated recently too. The plug for my rad fan had come loose and arced causing the fan to burn out as well as burn the connector. The fix was a new fan resistor and new plug for it. I upgraded the fan itself to a ford racing unit but the plug I had to cut off a wrecked car and splice in because none of the Ford dealers in my area could figure out a part number for said plug. They wanted 1500 for an entire new engine wiring harness. So I would check your connection and fan resistor. Could be the problem.

So check the plug and resistor? What should i be looking for?
I also got the ford racing fan, i put it in this morning but its still not working. Getting ready to take it to the shop since im getting pretty frustrated.
Can you post a pic of the resistor location?

It ended up being a sensor underneath the intake manifold. Shop replaced it for a new one and the fan worked.
