      Auto Tech hi and thanks gor tge feed back, sorry if you didnt understand the video.
      The video has a headline “ c class fan malfunctioning, keeps coming on all the time, and I specify how I diagnose and found that the ecu was faulty, so am not sure where I left you on this video,
      Thanks and I’ll try to be more clear, appreciate it 🙏🏽

      ok bro i pappreciate your efforts thank you , the fan socket have 4 wires one power , one ign , one ground and the last one is the signal from Ecu what i mean is to show your steps while working as the other technician like south auto repair and scanner danner do and if u look down 👇 u will see that there is another comment asking about the proplem . do u have my point 🙏

    Hi there, please help me, this is getting frustrating. I have a c300 2008 with a fan not working at all. I bought a replacement fan online, I mounted and connect it and nothing happens. Now I don’t know if there is something else I need to check (relay, Fuse) or how can I test if the one I purchased is defective. Any idea, suggestion please let me know.

    • @csctechdep5934
      @csctechdep5934  6 лет назад

      Jupacev hi there ,
      Sorry for the frustration buddy, do you have a scan tool , ?! And a test light ?!

    • @Jupacev
      @Jupacev 6 лет назад

      CSCTechDep Suli No I don’t have a scan. A friend of mine has a tester so I can borrow it. What do I need to test?
      We tried with some wires coming from the battery to the fan and nothing happened. Now I’m not sure if the fan I have is defective or something else may be the problem. How can I test the fan? What other things can prevent the fan to run?

    • @csctechdep5934
      @csctechdep5934  6 лет назад

      Jupacev I would check the basic things first like, fuses, and relay, then grab a test light and see if there’s power going to the fan, but scan tool can help you a lot and fast to figure out, like activating the fun, check the values of the A/C, engine temperatures, and ecu it’s self, sometimes it could be the fuse box not activating the fan. But eliminate the basic at least
      Good luck buddy

    • @Jupacev
      @Jupacev 6 лет назад

      CSCTechDep Suli I’ve been trying to find the fan fuse and it is not on the fuse diagram, I don’t find it on the web either. I found where the relay is on a website and the relay is fine. If you have an idea which fuse to check please let me know.

I checked all the fuses in the frond and rear they are fine. after that I disconnected the A/C control panel to see if the fan radiator won't turn on but in vain :( Is there anything other that I should check? or is it really my climate control panel that I need to replace?
