The fan for air conditioning and heater on my 2006 Octavia Mk2 L&K is not working. I have checked the fuses and they are OK. Does it have a relay that might have failed?

I am hoping it is not the fan unit itself, as this seems to be peculiar to RHD models with climatronic and was discontinued by Skoda in 2022. (Part no. 1K2 820 021).

Did you look at this:

Yes. Thanks, but it is not suitable for Climatronic, only manual air con.

Take the fan out and give the bearing a dose of light oil... Chances are its just seized up.

Not sure if the climatronic fan has a resistor pack. If its failed it may be the cause.

As Alisdair said. The highest speed is a usually a straight through connection. So if it works on highest speed but not others, then it is a failed resistor.

However some fans used with air-con have an electronic speed controller that is part of the blower.

I think all climatronic fans are going to have solid-state power control.

If this wasn't the case, the electronics wouldn't be able to vary the fan speed independent of user input.

Yes it does, but I have been told that if it fails the fan should still work at its highest speed, and it doesn't.

@eddie2 The Climatronic in our 2007 Octavia II 4x4 didn't have a separate resistor pack like our Fabia did - as @Breezy_Pete has said it was solid state powered.

I know as I removed it to fix it after it seized like yours.

I'd therefore expect yours to be too and the information you have been given about a resistor pack being present and faulty to be false.

As I mentioned - get under the passenger side of the dashboard and take a look at removing it and freeing the bearing up - it's one connector, a couple of screws and a bayonet type fitment. The bronze bearing can be accessed to oil it and free it up by removing the large rubber 'cover' on its base.

Just for extra clarity, the solid-state power controller for the fan is the part ringed in this photo, from an eBay listing of the part number quoted by the OP.
