2010 A/C problem

[Hen3.5]

I currently own a 2010 sho
My ac stop blowing cold and my radiator cooling fan stays on
Not sure how to approach this

Check you coolant level first. Then look for codes. Post back

I had that exact same issue a little while ago.

When the car is stopped and idling, the A/C blew warm air, but when I started moving again, the ac blew cold again.

Also, the radiator fans acted up by going full speed when the engine was at normal operating temperature. Also the cooling fans stayed on at full speed for about 1-3 minutes after I shut the car off.

First check your coolant level and see if your coolant Tempe gauge isn’t showing that your car is overheating. Mine was normal, so I knew it wasn’t a coolant level issue.


At first I thought the cylinder head temperature sensor on the side of the engine block went bad, so I bought a brand new motorcraft OEM CHT sensor and replaced it. The car was still blowing warm air and the radiator fans were still acting up.

So the next thing I tried (and this did fix the issue I was having) was replacing the radiator fan control module. This module sits right in between the engine and the radiator fans. You’ll see a silver looking module about the size of a smart phone. It bolts up to the fan shroud. All you gotta do is take off three electrical connectors and two screws. That’s it. And the whole module just slides right out. It just sits on two little arms on the bottom, and two screws on top of it hold it on the fan shroud.

I did not get a OEM module. I can’t remember the name but it was some aftermarket module that was a direct fit OEM style design.

When I changed this module out to a new one, the problem was fixed. A/C is nice and cold all the time now, and the radiator fans behave normally. It was an easy fix, and anybody with basic tools can do it at home.

Try this and I guarantee you it will fix the issue you’re having.

Shouldn't that failure set a code?

This post is spot on. I had had the same issue and the radiator fan control module is the solution. There was no Motorcraft module so I got a Standard module from RockAuto. The dealer could not figure it out so I read up on a.c. function in shop manual and eventually realized module was culprit.

How difficult was it to replace this sensor? Is it located under the lower intake manifold?
