When it happened to me while in FLA, the SA at Porsche of Melbourne that I spoke with said it was likely to be a sign that the fan motor was on the way out. I was looking at a ~1800 mile ride home through the remnants of a hurricane, and the dealer was not sure they could get a replacement for me before I needed to head home, so I threw the dice that it would keep working. That was October 2020. I did report the issue to my local dealer on my next service visit, just to get it recorded while still CPO. Of course, No Problem Found, and they were not going to preemptively replace the motor.

Hopefully it will stay fixed as mine has, touch wood.

To the best of my recollection though, it was not the day before I noticed the problem. The car sat in the resort parking garage for a day or so after the rain storm before I went out again and immediately noticed the issue. There was speculation that there was debris of some sort jamming the fan but I never bought that explanation.

My exact sequence was (1) drove thru huge rain Friday night, (2) drove about 80 miles Saturday everything normal, (3) car sat parked outside until Tuesday afternoon when I had the problem. That sounds exactly like what you did just before you had this. It was very humid here ... it's FLA after all. :-) How did you figure out how to fix it ? Thanks again you saved me from a high traffic frustrating trip to Porsche of Orlando.

Actually, when it first happened I did the obvious thing...look at the fuses, see if anything is blown. No problem found there so I started searching online and found several threads here and also the YT video. I really had my doubts that it would be something that simple, but once in a while, things DO go one's way. :-)
The beauty of owning a car like a Porsche with a rabid fan base and a dedicated web forum is that whatever problem you have, odds are someone else had it before and posted about it.

At first I thought of a fuse but when I saw it was a 40 amp fuse I was pretty sure that wasn't the problem, it would take a lot of juice to blow that ! But thanks to Asellus I did learn a lot about the fuse box and what a blown fuse looks like. I bought a membership to Rennlist today since the least I can do is support this sight which is an awesome tool for me.

This is a known issue. Porsche policy is that if the car is on warranty the fan will not be replaced by warranty and instructs service department to spin fan cage to restore operation. This will last until another humid condition occurs and condensation on brushes will cause another failure of fan. It's an issue for all 991.1 and 991.2 Porsches. Porsche did not correct this problem. Happened to me with my CPO 2017 991.2. I argued it was a safety issue as I drove 20 miles at night without being able to see clearly because of condensation on my windshield. As a safety issue Porsche agreed to replace my fan motor with the same new one with same faulty design. Four months later I'm still without a new fan and dealership doesn't return my phone calls.

Ah, I checked this last time I was in the car, forgot to update.
My owner's manual specifically states "bottom right" for that fuse, as you say. However, the embossed legend on the fuse box lid itself says it's on the bottom left. Not confusing at all, thanks VAG.
I'm wondering if we both have the weird owner's manual, since your page numbers match mine. In a thread last year some time where we were talking about tire pressures I discovered that my owner's manual not only has information on different pages than everyone else, but my comfort/full load tire pressures are different too. Other people with 2017s didn't match, same part number on the manual, all that -- we couldn't figure it out. Figured I just had some beta or misprint manual.

I'm hoping the new motor will have less tendency to experience this problem than the 5 year old motor that's in the car. I find it alarming that Porsche knew of this problem and allowed it to continue without updating the fan all the years of 991.1 and 991.2 production. Its a safety issue for those of us that live in humid conditions!
