Hi all hope your well,

looking for an AC relay on my Fabia (2) MK2 (Pre-facelift, 1.4L 16V)

 

The fans blow and the compressor isn’t faulty but no power gets to it so it can’t activate. I’m working on the basis that it’s probably either a relay or some wiring somewhere? Anyone had a similar experience..? (System is gassed and holds pressure) light for A/C even glows orange when pressed but no cold air.

 

Can anyone tell me where I should look, or where the relay would be in order to replace it - every single fuse is good and the batter has no issues

 

Thanks for any help people can give.

Check wiring going to compressor solenoid valve.

There's probably a reddish 2-pin plug/socket pair on a bracket near starter motor where wiring is often found broken.

No relays involved, except in fan control module, for fans.

 

Also check that all visible parts of A/C compressor pulley rotate as one.

Oh thanks ok, do you know if you can get at that yourself or is it more of a a garage job..?

They're both visual checks, but the wiring is probably easier to see from beneath the engine bay, with undertray removed.

I have no idea whether you have the equipment and skills to accomplish this safely.

Do not get underneath a car that is supported only by a wheel-change jack.

Pavements can be handy for creating safe space under cars with two wheels on, two still on road.
