Here is a photo of my armrest centre console that has the optional booster blower.

There are two wiring connectors in the very front of the armrest centre console that have to be connected so that the rear booster blower is operable.

My car did not have from factory this option.

My question is what optional wiring harness do I need for connecting the rear booster blower? I assume that the one connector is for powering up the motor and the other for controling the rear air vent and communicating with the digital climate control fascia.

thank you

 

here is another photo of the underside of the armrest centre console

 

i know u have wis so why dont you check there?

 

already checked. there is no booster blower retrofit chapter

since you have done this to your car you must know better what to do to connect it and what extra wiring i need just for the booster blower. it is annoying having the booster blower under the armrest and no way to make it functional at the monent.

 

Simply install the 581 wiring harness.

 

pardon my asking, but what exactly is this for again?

 

I need two harnesses i think... since i have to plug two connectors....

The one harness is the following: A 203 830 15 15

what part number is the other one i need? thank you

 

if it's not in the retrofit section check the main section so you know where it plugs into. THe plug the booster blower plugs into is part of the 581 harness like benzmodz said which is a feature that was never in your car so ordering the 581 harness would be a good start.

 

The booster blower is for the rear seat passangers. It is part of the factory climatronic (digital climate) package and pulls in air from along the walls of the center console and pushes it to the rear for the back seat passangers. The speed of the blower is controlled via the dial in the rear.

 

hey that makes sense. thanks! good luck with it!

 

I just checked the main section but nothing there, unless I cannot find it somehow. can you check sunman your wis and let me know if you find anything? thank you

 

hey my car never same with this feature can i have this how much would it cost to install it SUNMAN... and whcih parts will i need to do this mod?

 

the thing I did when I added that blower is look at WIS and get the electrical layout so that I knew what went where...then I ordered that same cable as goes into the armrest to add to the wiring that is already in the car (so that the armrest is connected per proper colored wiring)

keyword: WIS

greetingz,

 

Was this ever properly resolved with results and parts?

Thanks!

i have this factory fitted in my 03 C220cdi and my blower periodically has a mind of its own. if i have it set on high, it will run high for a while and then out of the blue it drops speed on its own then fluctuates back to its original fan speed (usually high)

Any suggestions for fixing this?

I thought it may have been poor contacts but that would usually mean full speed or no speed.

Anyways, im keen to hear any feedback.

 

Has anyone completed this retrofit and is willing to share info/pictures of the install and post about the results?

Looking to install and add to my digital climate controller (adding Sun/Solar and Smog/Multifunction Sensors)...

So far I found I have...

203 830 0308 Fan
203 835 0119 Cover #1
203 830 1313 Cover #2
203 680 0468 Liner
203 540 1913 Wire Harness

Thanks,
Jake
