BMW E39 Air Supply Issue: Replaced Resistor, Checked Fuses, Blower Works, Climatronic Fault?

Question

I will start all over again, so I replaced the resistor with the same one with identical numbers, it does not work. Fuses all ok, No. 8 this style behind the glove box even those in the glove box. The blower works. Is it possible that the climatronic breaks ???? Regeneration only works no...

Write to me, or if you touch the hedgehog to the mass with this heat sink, the fan works full steam? On one thin cable you must have 12 volts, after turning the ignition on the other cable, check if it brightens when you adjust the climatronic. Check and let me know

The schematics you look for on the BMW Wds are generally available

The airflow itself is there under the hood of such a so-called hedgehog, such a cube, see if there are any tarnished wires, etc., it is best to unplug the fan and connect the multimeter there and turn on the blower, it will not give 100% certainty that everything is ok, but if it gives voltage, there is a possibility of a fixed plug somewhere and the fan from the air supply needs a little electricity and loses voltage somewhere on the ankle

if this resistor must have the same numbers as it was originally because I do not know if it makes sense to buy because I have but with other numbers. and if I touch the mass on the attached ankle, the blower is on the max. or maybe the climatronic has failed, how can you check the climatronic? ??? buddy, this resistor is inside, not under the hood, I'm talking about 39 sedan here

If you touch this heat sink from the hedgehog to the ground, it's a fan? As it is, check this thin cable with an oscilloscope if it gets a signal from the climatronics.

Dawidws442 · Answer

with an oscilloscope, a strange method, a hedgehog has always touched the mass in this car, it is screwed with metal screws to the car's metal sheets, and what if it is a wire + a burned oscilloscope will it show? well, that's not what a universal multimeter is for, if you don't have one, buy the cheapest one for PLN 20, a one-time measurement should be able to check the continuity of the wires and the voltage on the hedgehog and behind it with the fan plugged in and turned on.

Buy a hedgehog with the same number and don't fret. Look what words will underline you in the editor because he reads terrible words with such errors.

malina156 · Answer

I bought the same hedgehog with the same numbers, it doesn't work either :shii:

The fuses are ok all. I have no idea what devices are you writing about, so is it possible that the climatronic has fallen ???? I have not checked the cubes yet, but 99% is ok. :shii:

Added after 3 [minutes]:

Climatronic supports all other functions only with non-blowing force :shii:

sebap · Answer

Did you buy a poor replacement or something specific?

melas · Answer

Car for electrician. You have no idea and the layout is simple.

malina156 · Answer

original replacement

Maybe I have no idea but I will do it. Melas, then write what to do. I checked the fuses ok. The blower is ok. I have two hedgehogs with the same numbers, the original Valeo and it does not work tomorrow, I will have a third, then I will be sure that it is not a hedgehog.

Added after 1 [minutes]:

I already have a multimeter so I will measure tomorrow.

malina156 · Answer

When I touch the mass, the fan is running at full power. Now check it with the same numbers.

Added after 3 [hours] 47 [minutes]:

so the climatronic remains on the thin wire there is no current at all. on the other two it is brown also not.
