Hi, I have a 94 S420 and hot air is constantly blowing out from the side
and front window vents. My core and valves look a little different….
would you recommend taking them apart and cleaning? Do you, or anyone else,
know of any rebuild kits for the core+valves on my 94 s420. Thank you and
GREAT VIDEO!!!!!!!!
if the plungers slide up and down inside the magnets and click when you
plug and unplug the wiring with the car running,it is prob. fine. When the
car is running and warmed up can you feel heat in the hoses coming in and
out of the duovalve?
good tips on the maf cleaner
Cool vid…..
warm heated air usually means the duo valve is staying open…either an
electrical fault ,or it needs to be cleaned..the sound under the dash is
the vacuum doors opening and closing to direct air to where it is needed
unplug it with the car warmed up and running…it should flow through by
default if there is an electrical issue..if it doesn’t the duovalve is
likely bad
Is coming warm water from engine to that duovalve, but is not passing . The
duovalve is getting warm too but, the hoses coming out are cold…
Now a small question for you.. My car (Mercedez C180 1998) make some crazy
noise when i turn the AC on. sometimes its like you hear a mouse running
inside the dashboard from driver side to passenger side. also recently i
turn the AC on, but instead of cold air I get warm heated air .. i wonder
if you have any idea what could possibily be the issue? Appreciate any
tips. Thanks Jay
I was amazed with amount of dry leaves laying around the a/c engine and
that was making the mouse sound when i was turning on the a/c, I cleared it
out and next to it I found the air filter, managed to extract that and it
was loads of dust and leaves dried out there. After assembly my a/c works
like a charm. no noise and the air flow is strong and smells clean :)))
Thanks alot for the tips Fupabox!!!!
Hi! Thanks for the tip! i looked under the dashboard on passenger side and
after un-screwing 3 bolts it lead me to where the aircondition fan is.
Godness,
Nice quick vid. I just wanted to add on my plungers that pull up into the
solenoids mine were stuck in the solenoids. I took some 1000 grit sandpaper
lightly sanded to remove the old goop and residue, and cleaned the inside
of the solenoids with some maf cleaner, just to remove the old goop. All
good works like new.
Well, I did unplugged but nothing…no warm water is passing… My duovalve
is an expensive one because of my auxiliary heater system, and hard to find
on SH spare parts. I will open again, and I will pull out that plungers, so
the water can pass this duovalve. Thank you sir for your help!
Awesome i have a w202 2000 merc c180! so ill now check if mines duo valve
and see if it needed cleaning! (probably as the heating seems to be a bit
slow) 😀
Hi Fupabox ? Thanks alot ! your videos are amazing. I am so happy you have
a Class 🙂 In a country where mercedez dealers charge US$ 220/hour of
labour and black market mechanics charge average of US$ 100/hour your how
to Videos are becoming Gifts 🙂 Thanks alot man!!!
Hello sir. I have a problem with my duovalve from my ’01 E-class. Is very
similar with the one you have on your car. My duovalve is clicking when is
on cold vent, but it seems like I don’t have any heat in my car. I opened
my duovalve and anything seems just fine, but again is no heat in my car.Is
posibly not to open that plugers because of that springs? Any ideea? Can
you help me please? Thx.
I used kerosene and it wiped down nice and clean
