Air Con Problem

Post by ubix418 » Tue May 15, 2018 11:31 am

Hi
I have a 2016 1.6 diesel manual. My air con keeps going form cold to warm. When It went into Nissan for its 2nd service I asked them to look at it, they told me not a problem and works fine. And it did for about 6 days afterwards, but now it only works for short periods and then it blows out warm air. Has anyone had this problem, Nissan are saying it needs re gassing but surely the fact it works for a few days then on and off means the gas is OK and should it run out of gas after 2 years (27k miles). Any help would be appreciated.

Pse always use SEARCH before starting new thread.
Input "air con condenser" and you'll see multiple threads on issue :P

w.r.t. re-gassing, if you have used the air con frequently then, as you say, it should be OK.
If you use it infrequently, there's a possibility that the seals could have dried out allowing coolant to leak.
Equally there's a chance that a stone chip has pierced the air con radiator.

There have been a number of threads about air con, the search function on here works well

one thing I have noticed with my air con

I always have the air con on and I always have it on "auto".
This makes the system work as a kind of climate control.
Therefore, when I set a temperature the air comes out of the vents as either warm air or cool air (sometimes freezing cold air) dependent on the temperature that the system measures in the cabin.
So if I'm sat in the sun for a while in winter, I find cool air coming into the cabin.
Likewise starting up in a nice cool covered car park in summer the system blows warm air and works to bring the temperature (cooler than the set temperature) up to the temperature I have requested.

Good Luck

My problem does not fit with the others. Today I drove 15 miles air con did not work. Got in car to drive 15 miles home air con worked all the way it’s just so intermittent I can’t find a pattern.

Sounds like you need to take the car to the dealers when its not working and making sure you don't turn off the engine. A total pain, but its probably the only way unless they can keep the car for a while & the mech drives it to & from work until he can see it fails to cool.
