Air con button not working Ducato X250

[GAVLAD]

Hello all

My air con button doesn’t seem to want to work.
When I try to press the button in, normally there’s a click and the light within the button illuminates.
Unfortunately it’s as if the switch is stuck in but the light doesn’t switch on.
I’ve checked the fuse and it’s the same as the cruise control which works so doubt it’s that.
I’ve just gone around the Paris ring road and was dripping wet through
Any ideas as to how to remove the panel and see if the switch is stuck?
Thanks

The most likely problem is that the air con system needs regassing. You are operating button, it turns on, then notices system doesn’t have enough pressure. Turns it’s self off.

Bloody typical that it’s only recently been in for a service. Suppose I’ll have to sweat it out to Spain then. Thanks for answering though

Go to any vehicle repair place and ask for a/c recharge and they will sort it. You never know when it will need to be done, so not fault of service garage. Some cars it last years and years and other cars a few years.
Last time I had recharge it cost £50. So budget on about £100 and hope not to be too much more

On our 2010 Ducato based Burstner, the air con works when the speed of the fan is on certain settings.

I dont think it works on the extreme left setting you show

If you were in the uk there are loads of places that can regas as you wait. No idea in france though. What a day for it to fail hey

Like me broken down with comfortmatic gearbox locked in gear. RAC turned up and said garage job. We will send a hgv recovery. That was 11am eta 4pm and I am sat at a roundabout roasting. Se la vie as the Frenchies say

And it seems to be on re-circulating not external air intake.

Check my post out on Air con on Fiat Ducato and check your fuse box out against the manual.

Absolute B*****d Air Con, 2010 Fiat Ducato

Todays episode, The Air ceased to work at some point in the last few weeks but only showed itself as it does when you need it most, well I went and checked both the fuses listed in the manual (more on that in a bit) meter says OK, I had the System regassed, to say the guy was busy would be an...

Yes defo one cause however and I do not have any experience of Ducato's but would OP not be able to feel switch clicking to on position when pressed. Even if it does immediate turn off...
He said his impression was that switch is stuck in.

As it should be!

Might be a stuck button as the light doesn't come on. (if recharge required the light would still come on but no cooling)

Try to flick the button to see if it will pop out. something like playing tidly winks with it. If not can you get to the wires on the switch and check with a multimeter the switch is operating / has a supply etc.

Good luck

check the three relays across the front of the fuse box next to the air filter first. With the engine running fan one no 1 button in. I think it’s the middle relay sometimes you have to take the relay out and slightly twist the blades to make a good contact. Worth trying costs nowt !!

I think air con only works on 1 and 2 fan speed settings. Will not work unless the fan is on.

 

[Landy Andy]

Mine works on all speeds, but fan must be on.

I have had numerous A/C unts in lots of cars and have never known them not to work on all fan speeds.. however wont work if fan off!

The switch doesn’t click or pop in, pop out when pressed it barely moves in and out and doesn’t “click”. That’s mine, (looks the same as your) but working

I had no a/c in France a fortnight ago and was recommended to go to a branch of a chain called 'Speedy', who re-gassed and replaced a couple valves / seals. Worked a treat after that - cost €180 (circa £150) - took about an hour-and-a-quarter, without an appointment.

But the on-off button was working and the light coming on and going off, provided the fan was / is running at any speed.

Another chain worth checking in France is Euromaster:

Good luck, hope you can get it sorted. It was a great relief to get ours sorted.

I have an X250 base vehicle - 2008 plate
My air-con packed up a few weeks ago.
It now shoves out air at ambient temperature
The blower fan works ok on all speeds
I can recirculate or get air from outside the ’van
The switch works fine and the little red bit lights up.
Initial inspection shows it has degassed (pipework problem).
Crank the windows down and smile……

Have you turned the fan on?

Ok I will try this tomorrow thank you

If it needs a re gas make sure the system is first pressurised and checked for leaks. Re gassing has been a big con for many years. The refrigerant will last for a very long time unless leaking.

 

[GAVLAD]

I originally had the fan set to external and only when the air con didn’t work did I switch to recirculate. So tried both but will try it all again

Indeed. I am satisfied the Speedy branch I used in France did check the whole system before re-gassing.

And mine might have been more expensive because they had to do because of the relatively modern age of the vehicle 2016 /17, which is when the EU implemented a requirement for new vehicles to have a more expensive refrigerant used.

The only difference between recirc and external is the A/C unit is more efficient, effective and economic on recirc because it is only cooling air that is already cool from inside van... in external it needs to cool HOT air from outside.

As long as the fan is on it doesnt matter if set to recirc or fresh air, As a matter of interest the aircon won't turn on if the outside temp is below 5 / 6'C. Not an issue ATM. Well not on a 2010 679 Kontiki.

Think you need to sort the switch, if no light it's not on me thinks.

Anyone know how to get reasonable access to the back of the switch? or even pop it out for a good look!

Think help in that area might be helpful.

Just had a look in the Ducato owners handbook for ours.

From your image on post #1, it looks like you have it on the correct settings for it to work.

However the more I read the last paragraph (red arrow) starting "IMPORTANT" at the bottom of the column headed CLIMATE CONTROL, the more confused I am?

I wonder if "last", should read "least"?

Update:
I’m on a site now so can have a prat with it.
The air con button works (illuminates) only on speeds 1/2/3 but the fan won’t work on theses settings.
The fan works on speed 4 but the air con button light goes out. Switch it to speed 3 and the light comes back on but the blower/fan stops.

The fan/blower did work the other day on settings 1/2/3 and 4.

Ooh yes, something a bit odd going on there?

Not sure what to suggest...

 

[Steve and Denise]

Only just tried ours last week and it’s not cooling as it should but being a 2018 just so happens to have the R123yf that costs twice as much as the old refrigerant Got it booked for next week

 

[poppycamper]

It is false that vehicle air con once charged will last forever... they dont.
Gas will naturally leak very small amounts to some degree or other over a number of years.
Every three years I buy a gas refill canister (about £50 with a £10 refund on return) and share it between the van and car. Just to maintain gas level.
Oh and never turn air con off, if engine running air con running.
