Technical 2013 aircon

Hope the op doesn't mind me tagging this on here :).
The aircon in our T/A(2012)works great for about 15 mins(sometimes less)then the output virtually stops & will sometimes just about work with fan on 4,anybody able to suggest where to start with it.

Cheers,Graham.

pressure is low, needs a top up.

Do you mean the aircon stops being cold, or that the fan stops blowing and no air comes through at all?

If the latter, this is not a lack of aircon gas but a failing or faulty fan speed resister, which is cutting out as it overheats. It will eventually stop altogether. There are various previous threads about this, such as here

https://www.fiatforum.com/panda-iii...-pop-blower-resistor.html?461475=#post4349646

and here (from the older Panda model - but the part and location is the same) https://www.fiatforum.com/panda/433230-smells-burned-plastic.html?433230=#post4133259 and here https://www.fiatforum.com/panda/287676-heater-motor-resistor-probs.html?287676=#post2909851

The resistor pack is about £15 from Fiat, and is fitted by accessing the heater ducting from the black panel beneath the windscreen. Remove wipers, remove black plastic panel - mostly a push fit but a couple of obvious plastic plugs too, remove wiper motor and linkages and then you can see the green resistor pack thorugh the opening below where the the wiper motor was where the air goes into the car.

But yes, if the fan is working happily and only a lack of cold after 15 mins, then @AndyRKett's reply is more likely cause.

Thanks AndyR,so is that the same thing as a re-gas ?

Hi,yes the fan still works(makes a noise)but the air output almost stops ?.

The air coming out the vents stops?

Is this climate control and the fan is powering down once the set temperature is reached??

It's manual air-con,with the 4 speed fan.
It's difficult to describe what happens,but i'll try & be a bit clearer :confused:
From the car being "cold" say in the morning,the air-con will start to work after a few minutes with cold air blowing through the vents,then after about 15mins the fan is still "working",but the flow of air from the vents drops right down,but what bit does come through is still cold & if the fan is switched to 4,it sometimes increases the flow,but not by as much as when it flows "normally".
Also there is a damp/musty odour when it starts acting up & ocassionaly a vapour comes out of the vents,now i'm typing this it sounds like we should sell it :D,except we love the car(mainly the engine).
Cheers,Graham
 
Very odd... but I think we are getting nearer the cause!

Have you read the threads here about cleaning out the drains from the 'scuttle' area -- the space below the windscreen where the wiper motor lives and where the air to the heater goes in? If you've never cleaned those drains (need doing every few months, especially in the winter when leaves fall in there), then I'd bet it is full of water. This will slosh around as you drive and get into the heater box, saturating the pollen filter - and once wet, air won't go through it too well.

Take a look here: https://www.fiatforum.com/panda-iii/475219-scuttle-drains-no-duckbills.html

If they are blocked, as well as water getting in the heater box, the carpet will be wet around where the steering column goes through the floor...

(Curious that you say 'air con starts to work after a few minutes - should get cold and the fan should blow, as soon as you turn it on)

Thanks for your help,i may be exagerating a bit it may be quicker than a few minutes,i haven't really timed it,but the air-con does work correctly at 1st.
I'm a bit of a duffer with mechanics,so i'm struggling to locate the "duckbills",i may be looking in the wrong place,so i'llhave another go tomorrow,busy today with a couple of events.
But once again thanks for your help.
Cheers,Graham.
