Hi !!
Blower fan doesnt work, regardless what speed i have selected on the panel ..

I had an enginefailure and had the Engine out of the car, and i have not refilled the AC yet, but the blowerfan worked when the AC system was without R134a ..

I have NOT read faultcodes, i dont have a reader..

But i have taken out the Frunk to get access to the fan assembly, and i have located the 2 big connectors..

There is 12 volt between the 2 big wires in one of the connectors , redblack/brown cables ..

The trapdoor in the assembly is working, i can hear it open and closing ..

and in the second connector, there is 12 Thin cables , and in the panel there is 12 speeds for the fan, or is the cables for something else ?

im looking for ideas to somehow try the fan by applying power to a cable or something, without disassembling to much of the car ..

Is there a blower motor resistor somewhere in the car or is the speed controlled by something else ?

I’ve taken the fanassembly of the car, and i tested the fan on a carbattery, the fan works..

and i have disassembled the resistor , its in the same housing as the fan, but there is no smell of burned electronics, and everything looks like brand new...

Is there a way for me to test if the resistor works ??

there is no faultcodes in the car. The blower just dont work.

found this connector in the passenger footwell, behind the fusebox, cant find where to plug it in ...?

i have tried a brand new resistor but it didnt solve the problem, i have disconnected the AC-pressureswitch, didnt work..

Is there any other sensor i can check ??
