Hi, newbie here, please can someone help?
The fault I have is as follows:
The heater blower fan is fading out and then stopping after running for a few minutes.
It does not seem to matter what speed the control is set to. My Octavia has Climatronic on it and the fan speed control is one with lights around it rather than "off-1-2-3-4".
It also does not seem to matter whether I set the Auto Windscreen button, or any of the other direction buttons (windscreen, face, feet).
Setting to Auto or having A/C on or off also does not seem to matter.
Whatever the settings for the other buttons if I turn the fan speed on after a period of less than 5 minutes the fan gradually fades out and stops.
Sometimes I can press the Off button then try the fan again - sometimes it works, sometimes it feels like I have to wait a few minutes.
I also tried the 'trick' of pressing the 'face' button and A/C button for a few seconds to run the flap reset cycle. This does not always get the fan running again.
I am fortunate enough to have a friend with a VCDS scanner that produced te attaced in relation to Heater Blower:
We ran a scan, then I turned on the fan to full and after a few minutes you can hear the fan slowly fade and stop.
We ran the scan again and the attached shows the only entry that changed.
I am not sure whether to replace the heater blower motor or the resistor or both?!
Any help appreciated. Thanks in advance.
(I have text files for the full scans but wasn't sure if I should post those or what 'personal' data there is in the file that might identify me/the car!!! Happy to post with guidance though!)
