I seek the inner working of the button of recycling of air (A126.820.50.10) of a 500SEC (w126.044). the button are six pins...
I think :
- pin1 => +12v (battery or contact)
- pin3 => ground
- pin2 and pin5 => electrical switch
- pin4 or pin 6 => interior lighting
it's correct?!?
I want use to activate manually a auxiliary fan on my W201. because, the summer the temperature of the engine goes up very easily, in the traffic jam or on circuit
can you help me? thank's you
if you want picture, tell me ^^
Solder a 1.1K Ohm Resistor (Mil-Spec) in Parallel to the block Temp sensor. That will cause the fans to come on at 92C vs 105C and will keep the motor cooler.
Okay, I have looked in both Electrical manuals and in pre '86 the Recirc button is integrated into the cluster. What model year do you have? Because the 6 pin switch didn't come into being until Gen II cars.
Yes, pics would be great.
Also, can you be a little more clear on what you want to do and the car you want to do it on and maybe I can guide you.
on my W201 2.5-16, I would wish to use it to order an additional ventilator. it is a A/C fan which I added. that would allow me to manually order a ventilator being able to cool the engine; because the summer it goes up very easily in temperature (especially in traffic jam!!!). I do not wish to touch with the original circuit of the main ventilator
I found that the illustration of the button was appropriate with use, otherwise I know that simplest would be to recover just the top to put it on a button like back lighting (simple switch)
in fact, it will not order the ventilator directly, but a relay which will order it (it would not like the current consumed by the A/C fan ^^)
so, if I understood well, I can use it like that :
[EDIT wrong diagram, do not use]
I shunt pin3 and pin6, for illuminated the button when activated...
(mayby, I should add resistor... lawl)
it received a (little) back shock and finished in an automobile scrap.
can be that there remain the bumpers, but the wiper was sold last month
I don't know the delivery cost to USA and I'm not the owner...
if you interresting, I can get information => PM or mail (general.lee AT mercedes-190 DOT fr)
I see in your profil, you have a ///AMG 560SEC! I love this car
do you known the 560 Koëning Special Edition, it's wonderfull!
Pin 5 Illumination ground - Brown
Pin 1 Illumination +12 - Grey/Pink
Pin 4 +12 from Fuse Boxed or fuse protected direct from Batt (Preferable) - Your choice I would do Yellow to batt.
Pin 3 to Fan. Your choice - I would do Red to your fan.
Do not tie to Pin 2 or 6
Pin 2 loops the voltage in a closed state and pin 6 tells the PBC that the Recirc is on.
Only my wheels are ////AMG, E-55's. Everything else is and will be (including the wheels) AMG Old School, Pre-Merger AMG. ////AMG is Post Merger. 90-91 was the cusp.
the wiper arms has already sold...
you can buy new wiper arm in Mercedes-Benz for 20-30€/unit (max ~$40/unit)
(for the correct price, I need the VIN code)
Yes, Headlight wipers. If you ever come across them, would you snag them and I will pay you. Thanks.. Also looking for a "Glock" box on the front of the seats... Storage box. Let me know.
What else is on that car? Can you take some pics and post. Maybe some other members need stuff if you are willing. I do that from time to time. Coupes are very Rare, Especially Euro ones. That hood is worth a fortune and so is the glass. Esp. the rear window. Ask TT, he stashed a couple of them and I am going to follow suit.
I already used the Light switch and the Horn select switches. The Dome Light SW for my CitiLights and the Horn for my Camera Select (Front - Rear).
I removed the Fader altogether as my DVD Nav does it electronically, and I used the hole for the camera select. I also opened up the two extra switch positions in the change cup for those that do not know they are there. One for the Shade (Used to be the ANT select) and one for the CitiLights.
