What happened if ML/GLE W166 fan is running as soon as the car starts when the engine is still cold, but AC seems to be cold, no problem with AC and scan with Xentry no code? Could you suggest some ideas? Thanks
Please mention model this problem is very common in benz mostly due to one of the faulty control unit Maybe fan control unit on newer models also there is one controller under dash driver side on mid models. Also go through live data and check for temperature sensors
@@CarFaults same as problem 👆. Ac working great, great, fan speed like plane ✈ even when car was left over the night. No specific errors, just undervoltage terminal 30. All fuses are okay, no corrosion on terminal/battery cables. Model w221 s500 M273 engine. Thank you in regards
I have Mercedes E220D, 2017 W213, I have a problem that the fan would still be running on max. speed for a 1.5 minutes after killing the engine. Knowing that the engine is Model 654. I have relaced the following parts: Fan, Turmos, Water pump, water back feed line. All original parts but the problem is still on. Also no fault found, could you please help me troubleshooting the problem? THANKS ALOT.
What is the typical norm (years or mileage) to have the Freon's recharged?. My W166 2016 GLE400 M276 Bi-Turbo. During the day does not get cold with AC and full blast but at night I can feel the cold air (AC turned on) coming out of the vent. I checked live view on my scanner but concern about the Interior temperature sensor it was reading at 36.14c (97F), B10/31 Left side air vent outlet 38.64c (101F), B10/32 Right side air vent air outlet 39.09c (102F), B10/7 Rear air duct air outlet 36.93c (98F) and B11/4 coolant is at 87c (188F) on my scanner. Going to check it today with my Inferred Thermometer Gun.
Did you check pressure reading during the day ? I suggest checking pressure reading with pressure gauge if compressor suction is good, then there is a chance of a bad condenser or filter also check for the actuators sometimes stuck at hot side. But more chances are bad compressor
I checked the reading during the day. We checked the Freon on the machine. I’m leaning towards a A/C Compressor Control Solenoid Valve. On a Snap-On scanner it was pulling a code B119C-07, switches automatic A/C is Jammed. The filters (cabin and dust) are new and it was changed not even a month ago.
Why does my fan stay on even with car off? My engine is not hot, I do not have any check engine codes so it’s no sensors. Fuses are all good and fan still stays on with ecu unplugged so it’s not the ecu. Any suggestions?
@@muawiamrwan6952 yessir brotha! Did a full diagnostic test on my car and it lead to the fan module! Replaced the fan and she turns off and turns on normally😄
@@CarFaults it runs when I turn on the AC there’s a weird sound but idk where it’s coming from. When the car heats up it goes away. I’m thinking it’s the Ac compressor.. there’s no leak anywhere at all. The radiator and the fan was replaced 3 months ago But I can’t explain why the reservoir suck up the coolant

Sir my ac compressor doesn’t turns on until I accelerate the car hard, then it turns on and functions normally but if I turn the ac on it blows normal hot air
Hi bro.i have c230 2007.when ı turn on AC the radiator fun is always running.what is this problem I don’t know.But AC normally cooling.help me please if you know reason this.thanks
You can check it by removing the engine temperature senr connector after removing fan should run at full speed if runs then all ok you can change temperature setting with scan tool if not run at full then maybe bad engine fan controller

@@nikolaisteklov686have u found out your problem?? I have a s550 with the same problem
Having the same issue however no codes fan runs on high a few seconds after I start and until I turn off. C63 w204
Same!
Check on live data maybe found any clues
@@CarFaultsthanks for your video check data for ac system pressure read 0 changed it out no more constant fun running. Thanks!

Thanks a lot brother ❤️
My c180 engine code 274910 when driving temp go to 45 degrees but when the car is Constance temp go to 85 degrees what could be the cause please help

My ac doesn’t get cold till I start driving and reservoir sucked up the coolant
Fan runs?
@@CarFaults it runs

Am an ac engr, pls what is the name of the computer for diagnosis
There is many diagnostic tools you can chose one depending on which cars you mostly work

Hello, my car has the same problem but the sensor is connected, what could it be?
Maybe bad sensor better run diagnose with scan tool
Sir my ac compressor doesn’t turns on until I accelerate the car hard, then it turns on and functions normally but if I turn the ac on it blows normal hot air
Possible compressor control valve
Mostly come with compressor
@@CarFaults mostly come with compressor means?
Hi bro.i have c230 2007.when ı turn on AC the radiator fun is always running.what is this problem I don’t know.But AC normally cooling.help me please if you know reason this.thanks
At full speed? Or it regulate its speed
My car has a similar condition issue and also the steering is very tight and no warming in the dash
Hi did you please figure out what the problem was thanks
Great job bro🎉
My glk 350 2013 a/c doesn’t work I check fuse and I check the compresor manual and compressor works pls help me .
you need to change your user name !! or contact the Local i.d.f service department 🤔
My ml 500 fan works at full speed, the AC cools and then stops cooling. What could be wrong? Could it be the fan?
Did your car overheat if you didn’t put the heat on
C300 2010 fans runs at full speed and ac works but not too cold why?
Compressor
Thanks Dorstah 🙂
Hello please why does my GLK 2013 SUV gets cool and hot different time.
The doors which handle cold and hot air are stuck to different locations.
Hallo, my w205 radiator fan spinning high when I turn AC on, maybe foulty pressure sensor?
You can check under the live data on diagnostic tool
i have the same problem , did you find a solution?
My Fan Does The Same And The AC Control Unit Is Not Working
Very good work
Thanks

Nice work
This is happening to when the weather is very hot
Mine too I hope it’s an easy fix too
A/C pressure sensor switch. Thank me later
Got lucky....Nothing actually broken.
Didn't work
Godddddd, saveeeeeeee, usssss
Correct
