Looking for ideas here…
Occasionally, the AC fan just does not blow at all. It appears the compressor is not an issue, just the fan.
I wonder if there is just a loose wire/connection somewhere?
Anyone have ideas on where to check?

Thank You in advance.

Check connections & f158 @ front pre-fuse box if fine, could be blower and/or regulator.

Thank you, Sir. Yet again.

Konigstiger,
Apologies but night you have the uninstall/install instructions for the regulator?
Is that behind/under the glovebox as well? I think I see it in the upper left corner of the screenshot in the blower pdf you shared?

Interestingly, a friend also found these TSBs. However, I am pretty confident they will not fix my issue.

Thank You

Bulletins are covered under MB factory & extended warranties. Replacement should have ESD by now regulator is plug & play located beside blower.
