jorn957

Hi, My name is Jorn and I have an issue with my AC in the Cayenne 957.
Maybe somebody has the same problem or maybe someone knows how to fix it before I go to the garage.

The issue, I've changed the fan blower (old one was making noise) and the blower regulator (just in case).
After this fix the AC doesn't work.

The new blower runs smoothly, it heats and makes no noise.
I've checked the cooling fluid and run a test for leakage in the system, all good.
I've checked again the new blower to see if I missed something, all good.
I've checked the fuses, all good.

Thanks for any assistence. Cheers, Jorn

Do you have an airflow problem?

You wouldn't check the blower motor if you had airflow but no cool air. In some Audi vehicles people have gotten replacement blower motors that were wired backwards and produced little airflow as a result.
If you have plenty of air moving but it's not getting cold, that's a different problem of course.

Thank you for the reaction.
I have no airflow problems.
When I set the temperature at LOW, cold air is coming through. But when I increase the temperature the cool air is gone (outside temp is 15 degrees).
Thanks again.
