I just don't see a clogged radiator on a car with only 17K on it....but always possible I guess...
At least I now know how to onitially deal with it if/when it happens again.
Apparently GM has never acknowledged or addressed the issue?? Recall??

When you say new control module, does that mean you had another part replaced or is it included in the fan assembly in the link? Do I need to buy anything else?
Just happened to my brother yesterday in his 2014 ...... Car overheated after a 30 min highway drive and then stop and go at the chik-fil-a drive through. It did the weak battery thing too where it wouldn't restart. He left it overnight and it started up fine this morning.

I just wasted my time and money. I went to the dealer and had them check the cooling fan and controls. Nada, Zip, Zilch! Everything tested out perfect. I can buy the part for $320 and do it myself but damn, that's why I have the extended warranty.
This is a PITA to get covered by the warranty. There's no friggen way I can get the car to the dealer while its having the fan snit and not do damage to the engine.

Just pony up and buy the newer fan assembly and enjoy the car.

Well, I just looked into my Helms and to replace the fan is an electrical connector and 2 bolts, IN /OUT. Have to remove the 4 bolts to get the air intake shroud off, remove the air intake from the TB and Filter and you have full access to the fan. The coolant hose is attached to the fan shroud but it is connected with 2 push pin type of attachments so they'll pop off.
Screw this whole thing. I just ordered the part and I'll do it myself in my garage. I might even take pictures of the project for the timid of heart who are afraid to remove a screw here or there. IT really looks easy, might eat those words but what the helll

It's easy... but you're replacing the entire fan assembly with shroud. You remove the duct to the hood vent, the air intake tube, and the coolant hose support. Then you unplug the connector (has a red tamper proof safety lock tab) and take the entire fan assembly out. Then reverse.
That's what I thought I said? Oh well, I got beer in the fridge and I'm retired so there's no time constraint. Just git 'er done.

I would like to do an electrical "autopsy" of your bad fan motor/module. If possible, can you remove the fan motor from the shroud (so it is easier to ship), and ship it to me? Send me a Private Message if you want to do this, I will pay for shipping.

Joo want my freaky fan/controller? Joo got it! We can work this out. It would be great to find a "fault" that can be pointed at to get this issue covered by GM or warranty.

Sorry to resurrect an old thread but this happened to me the other day with my A6. So I hooked up my diablo and data logged for a few days. Low and behold it happened again and my ecu was calling for 100% fan power but fans weren’t moving.
Dug around on here and found that the 2014’s appear to be the only ones with this fan. Looks like the Z51 and Z06 all got the larger 600 watt fan (‘14 Stingray has 500 watt).
I got the 600w “Z06” ACDelco fan from Rockauto for $197+ Shipping.

All 14's got the same fan (I have a Z51). The Z06 came in 15 and brought the "fix" fan with it. I never did hear back on the examination of my old fan and controller.

Anyone actually figure out the cause? Mine just crossed 50K miles and just started this on Hotrod Power Tour and I had to bail. Only does it after 30+ min on highway at higher speed. Restart fixed it. Zero issues side roads driving, only after 30 min highway. Just bought Z06 fan assembly which will have a new PWM controller on the harness.
