Hab da eine Anfrage aus USA erhalten und brauche mal Experten-Hilfe bei der Antwort:
ist ein E32 740i aus 1994, USA Ausfuherung.
Fehlerbeschreibung 06.01.18: Weird HVAC issue
I have a feeling it is soldering related.When put in the "manual" mode (face, feet defrost) I will have heat for about 15 minutes then it goes full cold, it will do it on either side. I have tried without the heater valves plugged in and it made no difference at all. When switched back to auto mode and it goes to the foot well vents I get full heat back. If I have the temperature setting on anything other than full it will operate at that temp from 5-10 minutes then go full cold also and heat will come back when switched back to the full temp position. The air coming out the driver side will be half the force of the passenger, it is not a broken actuator for multiple reasons, it has randomly started working correctly and will completely shut off when on auto with heat.
--------------------
Nach diversen anderen Tests hat er jetzt das IHKA auseinander genommen und berichtet folgende Fehler im IHKA Steuergeraet:
The blue capacitor on the left near the top of the board on mine is blown and I am not sure of the specification to order. The positive temperature coefficient (round blue piece in the middle of the board) is blown and I do not know the specification.
Finally for the last one the MOSFET at the left on the top left heat sink is blown too and once again specification is not known.
Would anyone possibly know the spec of these pieces? I would try and look myself but I only have one of these.
