VIN confirmed PR-code KK1, which indicates R134A. Had it read KK3 instead, that would have meant R1234YF.

If low speed function fails, when A/C is on the fan tends to run in short bursts of loud, full speed action punctuated by not running at all. Is that what you're finding? Obviously most noticeable when car is stationary, idling. What should happen, if A/C is active/cooling is that the fan should run continuously at low speed (if ambient temperature is warm/hot).

Scan for fault codes.

Or your sticker isn't correct. Message me with your VIN if you like, I may be able to find something out for you.

I would expect Febi parts to be OK, probably a safer choice than the very cheapest options. No reason to expect the replacement connector to have any trouble fitting. The most crucial part of using any of these kits is probably to make sure that all wires still go to original destinations after the work is complete. I saw a brand new loom on LLL parts for about £95, which might be quite a time and effort saver if you could DIY install it, compared to the repair kit. Either way I think - if memory serves - that removing the door speaker makes accessing the loom where it disappears into the door much easier. I'll add a link or two in a minute, just out walking in the sunshine 🌞. Skoda Wiring Set For Door 5J0971120HG - LLLParts A post with instructions for door loom replacement: https://www.briskoda.net/forums/topic/379347-broken-loom-wires-at-drivers-door-hinge-connection-fabia-ii/?do=findComment&comment=4461179

I would expect so, but usually require some sort of tool, usually with a pair of stiff wire prongs an appropriate size and spacing. It might take a bit of finding, but I think a while back I acquired a connector like this with a set of pins, which I could experiment on with the various depinning tools I have. Was your plan to use the existing connector and most of the existing wires, but just de-pin the broken/damaged wires and replace with ones from the kit? Do you have an idea or photo of how many wires are damaged?

The kits being referred to tend to be an unpopulated connector plus an ample supply of wires with appropriate pins pre-crimped to one end, ready to be just pushed into the connector housing. Typically then you'll get a supply of inline/butt crimps to make the other end's connection to the existing loom. This listing lacks the inline/butt crimps but shows the general idea. https://www.ebay.co.uk/itm/394789687716

Mk2 Fabias are notorious for it. A few other Skoda models too.

The idea with those repair kits is that you push the necessary number of wires into the relevant positions of the new plug, then splice-join to the existing loom somewhere well inside the door, so the joints do no flexing. I'm struggling a little to picture what you've described with the multiple smaller connectors at the A-pillar on a mk2. How does the rubber boot seal it all up against the elements?

Correct on the 1.5, but according to this, 0.5mm is 20 gauge: Metric-to-AWG Conversion Chart | Technical Resources | Lapp Tannehill

My 53-plate petrol Polo is compliant. No plans to get anywhere near though.

The thickest two wires (power and earth for the window motor) are 1.5mm² cross sectional area of copper, the others are either 0.5 or 0.35mm², so if you used 0.5mm² everywhere except the two thickest, you should be OK for repairs.

I think that last bit about someone having a go before must be the explanation for what you're finding. £118 sounds like £98.70 + VAT.

Will check wire sizes after I've eaten, but that VIN gives 5J0971120HG as the current part number for the loom, at £98.70 + VAT retail. That has a single (28-way) connector at the A-pillar, like what you're seeing in the repair sets suggested earlier though.

That sounds more like a mk1 Fabia? But a 2011 1.6tdi Fabia has to be a Mk2 🤔 Can you tell me the VIN, I can look up loom part number for you, and wiring info with that.

That suffix-C part isn't showing as having been superseded by anything else either.

Yeah, just found it actually, but only listed for cars built up til 29/05/2017

That link goes to 566941016C, I'm not sure that 567941016C is an available part number, Skoda-parts.com doesn't seem to find it, nor OEMwolf, both of which are handy sites for checking equivalences. Are there photos of this part number in the listing you're seeing @Vista321?

Alternators in recent cars with start/stop will not put out a constant 14.5V, so are no longer easy to test. An independent test of the battery at a non-Halfords establishment is a good idea.

Or being sprayed out of jets to cool pistons...? Sorry, not buying it.

No, I doubt it. It's always in contact with air anyway, once you pour it out of the container.

I think air is able to find its way out of oil...

No problem. You get nice surprises sometimes with things being less than expected. Not often mind!

Retail price appears to be £39.50 + VAT at Skoda dealers, so £47.40 by the time it's in your hand. TPS may be cheaper, if you can blag your way to getting served. LLL parts generally are cheaper, even after postage, but I'll leave you to check that out, by starting here: Skoda Satin Black 5E98677669B9 - LLLParts Not usually lightning-fast with delivery, but if you were previously going to wait for it to come from afar, then that probably doesn't matter.
