Thanks for figuring this out and making the video. My '06 c350 having same symptoms as you described. I had ruled out all the other possible causes and was planning to take to the dealer on Monday. You've given me hope!

Excellent. Thanks. Why spend thousands, when one dollar with knowledge will do?
My people are destroyed for lack of knowledge. Thanks again for sharing this info on the benz.

Hi George I have a 2014 Mercedes B180, recently I have problem it displayed "Coolant Stop Engine" I see that the fan is not working but the Mercedes dealer said that the water pump has gone bad. I am surprised to see that they come to such a conclusion even before they make the fan functional. Would you believe this? I need your expert advice what I should do, I am in Mumbai India. Thanks.

Hello, I have a 2002 clk430, my heater and ac fane never shuts off even when key is pulled back, lots of people say it's the resistor but I think it would be a relay, do you think what u r showing is the same?

Hi George, I have a 2011 C200, was in and accident, and I have the same trouble, The cooling fan was in the safe mode, I replace the blown fuses from SAM module, the AC works, but now the cooling fan not start when the temperature is High

Thanks George! You are a legend mate! :)

Thanks for the Video... Its one more thing for me to try. I have a 2004 W209 Temp Sensor works but Fan would not turn on. I replaced the temp sensor same thing. If I unplug the sensor the Fan does turn on High. I am getting no Codes and using the Maxis computer I can control the FAN through the ECM and vary its speed in test mode so the Fan to ECM seems fine and the ECM detects the temp sensor unplugged. The only thing not happening is the fan turning on at temperature or when the AC is engaged . Hopefully there is a hidden fuse that has blown.

Hi where did u buy this fuse, kindly help me i have the same fuse blown .

[manny]

Is the cooling fan the same as the ac blower?

[marharris]

George great you tube. Wish I would have found it  before I removed and repaired my SAM module. Where do you get the fuse. I am using 100amp boat fuse but would like to replace with original.

Hello, I have a similar issue on my 2009 w204 220 CDI. The cooling fan is not working, but if I put 12v power and bypass the steering module it works. It also works when the AC is on, but very slowly. Can it also be the SAM - module?
Best regards

Жорик, на w218 ошибка - сгнал по шине CAN не достоверный. Эелектро усилитель заменил (мотор) мертв. Может ли это связана с фьюзом в префьюз боксе? Спасибо.

Thats not the front SAM, its the prefuse box.

Hey George...question...This is what my dealer is telling my wife: Cooling Fan Assembly Replacement. The engine fan is losing communication with the engine control module causing the fan to run at full speed. Its a 2010 GLK the cost for the parts and can I fix it? I looked online..the OEM sensor was $50 and the cooling fan varies from $205 to $300....they want to charge me $861. Thank you. if anyone else has the answer....I would greatly appreciate it.

So what would cause a 2010 glk 350 to not start and have no power windows, mirrors or panoramic roof. Also the steering wheel is not locking with the key out. I would think it would be the ESL but why won't the sunroof or windows work? Makes me think relay or fuse. Help?

[mrapter]

Can you tell us what the part is called so we can rebuild ourselves?

[georgikuzmev]

Hi George, good video! I have a same car as on video with a fan trouble. In my case fan runs constantly on max speed 3 seconds after I switch on the engine. Goes off straight after engine off, regardless of temperature or anything. All sensors, liquids, AC, fuses seems fine. What do you think? Is there a chance to be the relay you talking about in your video please? Some ppl say its the engine ECU?. Thanks

[aptechknowledge]

Yeah but why did that fuse blow in the first place?

[CristGibson]

Can you send me the link for the multi fuse in the Sam module
