Dead blower Skoda Yeti.

[Easternlight]

As the title, the fan for the heating has stopped working.
The car had a flat battery after standing over christmas so wouldn't start on Tuesday, charged it overnight and it started OK but the blowers stopped, doesn't do anything, checked the fuse and its fine.

Scanned and got the code 9485831 which reads as blower heater fault!

Is this just coincidence or could a low battery stop it working, not had a chance to meter it yet.
The battery is getting a bit tired so maybe pulling the volts down?

Any ideas

The battery on my wife's 2019 Skoda Kodiaq went flat, and a lot of the electrics went mad. Skoda had to reset lots of faults.

My Karoq heater blower stopped and that was a shorting out pressure sensor in the air con. When I was researching my problem I found loads of cases of Yeti fan relay failures and there are YT videos on how to replace the relay.

Thanks for the replies.
The problem got worse on Friday when the car failed to re start after being driven 4 miles.
Battery very flat. The battery charged OK and voltage looked good but there were no amps to start the car.
Put a new battery on it and all good but the blower still did not work,
I removed the blower this morning and by the time I had manoeuvred it out It was turning but a little stiff and it would spin when powered up.
I removed the motor and it did look a little rusty (see pic, looks much worse than it was) I cleaned it all up and applied some 3in1 to the bearings and it felt much better.
Put it all back together and all seems fine now.

Not to bad to get at, removed glove box and one piece of heater ducting, just a bit fiddly to get it in and out of the housing.
