hello guys !
so basically the driver seat ventilation doesnt work. i press the button,stay blue for 1 sec the turns off automatically.on the tester it says . sometimes it work for a while but most of the times it doesnt stay on.
i read on another thread about this error/its because of the seat temperature sensor (faulty sensor/wiring) and that if i plug a simple temperature sensor ntc 10k ohm should fix the issue.
the problem is that im having trouble identifiyng the correct plug/wire from under the seat.
on that thread ive seen many photos but some are of the Panamera and wasnt the same colours.
i need specifically for the Macan. ive attached some photos with the underseat wiring/ plugs in hope you guys help identify the correct plug.

the original post i read about the fix : https://rennlist.com/forums/cayenne-...to-time-3.html

 

I think it is the 4-pin connector in the fourth picture (two fingers are holding the wires).
The two thin wires (Black with White stripe, and Green with Brown stripe) is the thermistor for the seat bottom cushion.
The thick Brown wire is ground for the heating element. (This goes to a chassis ground bolt). The thick red wire is +12V for the heating (Goes to the AC Control module which switches the +12V to this.)

Unplug that 4 pin connector and use your DMM to measure resistance between the thin wires, it should be around 10K Ohms, +/- 2K Ohms. (around 72F)
Between the two heavy wires should be probably 1 to 5 Ohms.

These measurements are to the part of the connector that goes into the seat cushion (with the heavy blue wire), not on the connector end that goes into the car harness.

 

thank you so much for the reply ! ill test it out asap and ill keep you updated !

 

Reread my post, I had to correct it at 11:09AM...after you initially saw it.

 

i ve reread it so if i want to do the trick with the online-bought thermistor, i have to connect it to `The two thin wires (Black with White stripe, and Green with Brown stripe) is the thermistor for the seat bottom cushion.` corect ?

 

yes, correct

 

Slightky off topic........but is there a filter for the cooling fan ? I have seen these small filters for Infiniti etc cooling fans.

 

no

 

it worked !!! thank you so much !!

 

Hey Paully, very glad to see that this worked for you. I just wanted to ask if it fixed both the heating and the fan?

I am about to try the same thing.

 

yes
both works now
