Demister/AirCon problem

[MilgeS]

Bit of an odd one this, started a couple of days ago.

 

Just demister on fan speed 1 it only seems to work when it wants to, aircon light doesn't come on, fan speed 2 and above all is fine

 

Usually when you turn the airflow to screen the aircon comes on, only works on fan speed 2 and above

 

Any ideas? Thanks in advance :-)

You never had very low temps down your way did you and A/C disabled due to outside temp?

 

Looks like a A/C check and maybe top up needed, 

as to Electrics, i have not a clue on them, and what does what.

I only ever put A/C on Manually now and again to give it a bit of a work out.

No low temps here, only -1 or -2 a few times

 

I wondered if it just needed a "service" to sort it out, I only use it for demisting in winter, cool in summer, just seemed really odd to not work on setting 1 but fine above that! If it weren't for the fact I was demonstrating turning it to the screen and pointing out that the A/C came straight on (or not in this case) I probably wouldn't have noticed.

 

I'll get the A/C serviced and see if that helps, thank you very much

Made a couple of quick calls to dealers and they mention a resistor is a common problem but that makes the fan run on setting 4 constantly, so that isn't the problem I have. They also don't think a recharge will fix the problem.

 

I'm going to vary the speeds using the fan this week and see if it sorts itself out, I can't think of anything else other than a new motor?

 

I doubt this is covered on the extended warranty either

The resistor can also fail so setting one does nothing, no output.

Pretty well covered on here.

It's happened to me on my Roomster and Fabia. Speed 1 stopped working both times. The resistor was replaced both times, under warranty on the Fabia. The Roomster was too old but I don't think it cost much to fix. It's only about half an hour's work.

sorry, can't edit. I should have sai speeds 2, 3 & 4 worked ok.

Ahh thank you, I did do a search but couldn't find anything specific to setting 1, many thanks :-)

Thank you very much, I will look into getting the resistor changed, I'll check the details on the extended warranty but I seem to think electrical wasn't covered. Many thanks for your reply

Just to update, I took the car to the dealer when I could eventually fit it into my schedule, they were going to "have a look at it", after an hour the service manager came over and told me they had changed the resistor and all was ok, just waiting for confirmation it is covered by warranty now, should be ok as I have the "All components" cover.

 

I had to bite my tongue when he told me it was the resistor as when I called then initially,I told them the info I had from this page, and their response was "To be honest, forum people don't usually know what they are talking about, when I was a VW we had resistor faults and they ALWAYS stopped working apart from setting 4, so it's unlikely it's the resistor causing the problem", how I didn't laugh in their faces I don't know!!

I've spoken to dealers before and mentioned things on here that is pretty solid knowledge sort of thing and had the same response, "oh I wouldn't believe what you read on the forums"
