Whilst there's a range of possible issues, the most common is simply a fault with the clutch coil not engaging, which means that the compressor isn't spinning to give you nice cool air.

A mechanic might give you a typical quote to replace the coil, compressor, and re-gas... but that'll likely come out at the cost of replacing the car!

So, a bit of fault diagnosis on your own may present you with the opportunity of an easy fix, or at least a simplistic fix by an auto-electrician.

To check if you've got a common yet simple to fix issue, pop open your bonnet and start the car up, turn on the air-con and see if the a/c compressor is spinning (ie, is the clutch engaging).

If not, then you're likely just up for fixing a couple components amongst the clutch coil where a small themo fuse and a diode that sit inside that cost a couple dollars are hiding inside. It's pretty unlikely that the coil itself is gone.

This is where you can get the help of an auto electrician, or get your hands dirty.

But getting your hands dirty and working out how to access it to pull it out and fix is a bit of a drama though... removing the front right wheel and plastic shrouds will give you access to loosen the belt tensioner, get the belt off and remove the three mounting bolts that hold the compressor in place.

Getting the screws off the A/C clutch plate is awkward though... you need the Torx screwdrivers and it's hard as hell to crack open. But once you get the screw removed, you can go on your merry way to removing the clutch plate, removing the circlip holding on the pully, and then the clutch coil that's also held on by a circlip.

There's a few videos going around of what's involved including this one by Mechanical Mentor on youtube:



If you end up in a complete mess, don't worry too much as your A/C wasn't working in the first place and there's no harm in removing it and not bothering to hook the belt back up; plus you'll likely have learnt a lot along the way.
