It seems to me that I have this problem.

On the other hand, a charitable soul could summarize the problem for me, because passing each time with a translation is quite complicated.

There is something that is clogging but I can not understand what ....

All the cases thanks to you.

hi

Think things are getting lost in translation , have a read of my previous posts and pictures

there are other things that can cause this that’s why it’s so important to get the codes

Plse keep us updated

Hello

I just had my icarsoft 930, and I come back to you with the error codes.
The ventilation servomotor must be the cause.


Code B1b74 B1b75
Defrost ventilation mode servomotor, front floor

Code B1b76
Servomotor of the mixing valve left

Code B1b77
Servomotor of the mixing valve right


Code U3000
control module

What do you think ?

Thank you

Clear the faults and see what comes back, some may be historical.
 
ok

So I have to remove all the dashboard and the glove box like him?



And after I look if it's the connectors that do not work anymore ?



That's what I circled in red, the connectors?

Hi

just quickly and don’t know if you have, but u should be able to use ur diagnostic to operate each and every motor

seems weird 3 x are faulty , just trying to think where the ecu is as maybe there’s a bad connection, bent pin inside the connector that fits onto the ecu

just a thought to check before going any further
 
Hi, thank you for your reply.


It's true that it's weird because I have hot air on the right while he tells me that there is also a problem on the right. Code B1b77
Servomotor of the mixing valve right

No I can not operate each servomotor with the device, either I do not know very well use it or we can not do it.

I think about this second hypothesis because I really have to watch everything.

But if it's a problem of connection or pin, I have no choice to disassemble everything.

ive managed after some digging to find the connectors and what each pin is connected to

so at least then ur be able to see if power is coming out of the ecu towards the motors

also I’ll do some more digging ref the fault codes for u
