Evening all,

Not sure if anyone else has had a similar issue but the air con has stopped working in the other half’s Up GTI. Bit frustrating really as not long had it back from its first service.

Fan blower is working, light on air con button illuminates, but can’t hear the compressor kicking in & no cold air.

Couldn’t find a fuse guide to check which fuse it is - all the pictures detailing fuse box layout show a completely different fuse box to the one in the car!

Anyone else had this problem?

Hi there,
That is annoying. Are the pictures you're refering to in the manual (which I know from other posts bears little resemblence to reality for the GTIs), or online ones? If the online version is wrong, do you have a post-2017 GTI (less info available publicly for these)? Any chance you could send us a picture of the under-dash fuse box in any case; might be able to cross-map it with the standard cars and deduce the right one.
In the standards Up!s the AC relay is on a 15A fuse (one end of the top, small row of fuses) while the control unit is on a 30A fuse (same end as the 15A but in the bottom, large row of fuses), which might narrow down the options somewhat.

You can't really hear it kicking in as it is running when ever engine is running. So called modern compressor which is quiet. You may want to test it again when weather is warm. It might work just as it should.

Or could it be a gassing issue? If everything is blowing as it should it probably is that.

I've not heard of any compressor issues yet with this model, usually system is low on charge through damaged air con condenser if it doesn't work after system is recharged. An easy way of checking for you, with air con switched on and blower operating, if you can hear a hissing noise from dash area it's a sign that your air con is low on gas.

Hi all...a stone-holed condenser maybe?On mine,you can actually hear and feel the compressor kick-in no probs.Also,if you watch the Tacho whilst you hit the A/C button it will drop 50rpm or so if it's working as the electro-magnet type clutch on the compressor consumes rpm and power. Also, your foot on say the brake or clutch pedal will sense a tiny vibration as it kicks-in or not!! Also,open the bonnet, put the A/C switch on and then feel the A/C hoses.Within a minute or so they will be a lot colder if it's working. Hey good luck!
