I just cleaned the contacts. One plugs into the regulator and the contact plate was bent away from the blade that slides in. When its warmer, I will clean the blower correctly. It turns always. Surely is can use a cleaning. They disassemble very easily.
Hi , I have a 2005 ml 350 . Sometimes the ac work , but if you turn it up higher, the air will be hot like you switch it to heater. What do you think can be the problem ? When the ac is working, the air seem cold enough like it doesn’t need Freon . So I’m thinking it’s not low on Freon.also the fan doesnt on low setting . It only runs when you put it on higher setting. But then if you put it on higher ac setting , the air will come out hot.
I Have A 2004 550Ml Mercedes.. I Replaced The Fan 3 Days Ago (Brand New) It Was Working Fine, Till The 3rd Day, It Stop Workin Fuse & Relay Are Good What Can It Be?
@DallasAutoDiag I Found Out Why The Fan Wasn't Working.. Ac freon Was Super Low So The Ac Clutch Wasn't Engaging & That's Why The Fan Wasn't Coming On.. Found The Leak & Have To Bring It To The Ac Shop.. When I Added Some Freon The Fan Came On...🤦♂️
So what was the actual issue? When the radiator fan does not operate as expected and throws a code, usually it's the fan control module on the fan motor or shroud (depending on model). The issue is usually intermittent, which would explain your code going from current to history. Some research shows the actual issue is some of the cold solder joints in the module.
I have a similar car GL 550 2009 and when I start the car the AC comes on and works grate but after a little while it goes off and does not comes on, so what you think could be the issue
Thank you for the video, i have a 2015 W205, fan goes high speed with ignition on, main power and grounds are ok, so is the 12v from ignition on. on the lin control wire, there is a steady 10.5 volt, even if i unplug the fan, so this points to a faulty ECM or a lin wire shorted to b+ somewhere, or am i missing something? is there a direct connection from ECM to fan on the LIN control wire? thank you
Also the electronic coolant pump is Running at the same time, could it be faulty? I found in wis there should be a lin connector under the wipers, maybe water there? Thank you
@@jakubkusa That confirme my theory more. Mskes sence more that the pcm powring both on because he sees somthing else that he doesn't like. A high temperature or something
Well i still suspect the ecu, since it has no control of the fan.. it should send a square wave when i command it bi-directionally, right? All the sensor values are good :(
HI , I have a 2010 e350. My car's radiator fan acts all funny when the car is turned off. It keeps going on and off for 10 seconds each time. initally its very low so you can barely hear it but a few hours later it gets really loud and keeps the same sequence of goign on and off. i took it to a few mechanics including the dealership but no one has been able to fi it. Would appreciate some advise. thanks
Is your problem fixed?! If yes, what have you done to fix it.. i also have the same problem with my e350 I've replaced temp sensors, coolant and the radiator fan as well (even washed the radiator with pressure washer) still the problem persists.
I have the same problem but the cooling fan still runs high speed even with engine off… so I plug the scanner and the deleted the codes and it work normal for 3 days and the cooling fan turns back on high speed even when I unlock the door. Could it also be a command prompt???
I have same issue on a 2012 GL 350 ... fan will not come on. The plug has power. I am on my second fan and still nothing. So how was this issue resolved?
Hello, I bought a 2005 C320 that was working fine ,next day after driving it for 15 minutes, 30 minutes after I heard aloud noise coming from the drive way and it was the cooling fan on full blast, and soon as I started the car the fan slowed down then came on as soon as I turned the engine off, I unplugged the battery overnight, then ass soon as I plugged it back the fan came on on a full speed while the engine off
Hello mate good evening from Australia I have a Mercedes’ ML300cdi fault code *Check component M4/7 (Engine and AC electric suction fan with integrated control). Positioner signals fault. We have plugged Mercedes’ Star into the car and tested the fan with speed test , in which the fan works , but whilst carrying out the test the response it slow when you want it to speed up it won’t you have to wait or keep increasing the speed using star , the reason for carrying out these diagnostics is because after about 20 minutes of driving I get the thermometer pop up on the dash but live coolant temp is fine , any suggestions would be great cheers Mate
Old comment but deserves a response. You have to use a bidirectional scanner and plug it in the OBD2 port under the driver's side dash. Bi-directional, because these can tell the car to do things instead of just reading codes. But you have to do some research to make sure the scanner does what you need it to do. Google "good Mercedes bidirectional scanner".
Superb👍

Can you do this without the computers ?

Look somewhere else. Something in the car is telling the pcm to power the fan on the moment you put the key on.
Also the electronic coolant pump is Running at the same time, could it be faulty? I found in wis there should be a lin connector under the wipers, maybe water there? Thank you

Lets start with a full scan report to see if there are any codes that could cause this issue.
Is your problem fixed?! If yes, what have you done to fix it.. i also have the same problem with my e350 I've replaced temp sensors, coolant and the radiator fan as well (even washed the radiator with pressure washer) still the problem persists.
@@taquizaffar3908I have the same issue on mine… have you found anything ?
@@ivanrodarte9508 yeah, it’s fixed now.. in my case EGR was faulty.. just disconnecting the EGR fixed it.
I have the same problem but the cooling fan still runs high speed even with engine off… so I plug the scanner and the deleted the codes and it work normal for 3 days and the cooling fan turns back on high speed even when I unlock the door. Could it also be a command prompt???
You have another issue. The computer is putting the fan on all the time as a protection procedure for another issue in your car.
The ac system on my car doesn't want to fill with freon, what could be the problem?
Yes, the problem is either you are trying to do it yourself with the wrong equipments, or your car in the wrong shop. Pay a pro to diag it.

Oh boy, that might be a challenging diag. Sorry can't think of anything without being there, scanning and looking at some live data. Good luck
No worries cheers anyway matey 👍
Okay. Please provide a more detailed step by step. What software are you using for reading. Where do you plug in to get diagnostic? etc....
