Hi all,

I recently bought a Tekna 18 plate.

Today, the aircon was turned fully off, and several times it turned on by itself and went to full on.

Just a quick query, can this happen in auto mode? Or do I have faulty system!? :roll:

Any help would be appreciated!

Welcome to the forum.

Unfortunately I can’t answer your question, I have never turned my air con off other than very short local journeys when it’s spanking hot outside.

Hi!

Thanks for the response.

You never turn it off?

Out of interest what temperature do you have it set at?

I have it running at 17.5 or 18 otherwise it can get stuffy
If it’s really cold (winter morning) I set off at 20 or 21 and turn it down when I get warm.

I never thought about keeping it permanently on. I’ve noticed a few people now mention they keep it on...

I think I’m still thinking of it as an old car without climate control.

Well,
it’s extremely rare that the car mists up
it’s usually a comfortable temperature
the seals on the air con system never dry out

It’s 10 years since my first car with air con (a 51 reg RAV4) and it was advice from a rugby pal who sells used cars that it was wise to run the air con as often as possible to guard against breakdowns

I had this on my 1.2 N-connecta last year.
Solution was the car battery was on its way out. (myself and nissans only explanation) as it stopped when a new battery was fitted.

Also at the same time as the AC turning itself on/off on its own problem (always on a start up and not randomly whilst driving). I had the radio start up with the USB device active instead of the radio which was selected (on) when the vehicle was switched off. (strange).

Can only suggest charging your cars battery and dont use AC lights wipers etc for a while to help charge and see if it goes away. Alternatively try a new battery. Cured all the strange un explained faults.

Hi,

Thanks for that. Interestingly when I have it on LO, it comes on but if I turn it off when the temperature is set to around 18, it hasn’t done it yet.

I am keeping a close eye on it now, but will be very mindful of the battery. I read that the batteries were a common error with the Qashqais!

Thanks for the reply.
