Ideally you need someone to help you with this although I managed it on my own. With your head under the pedals, staring straight up you need to pull the wiring loom through from the passenger side. Having identified the cable from the back of the heater controls, down and out by the pedals and then up. Tie a long length of sturdy string to one of the connectors you've just unplugged and then tape all three together, neatly so they take up as little room as possible. You can't really see it in this picture but just follow the lead up and you'll find it. This one is tricky to get to - it activates a flap when the recirculation button is pressed. The two shown in this picture are to the fan itself (left) and the resister (right). One is very high up and you will need to be on your back with you head as far into the foot-well as possible up against the bulkhead. In the passenger foot-well there are three blocks that need to be disconnected. You need to work out for each one which bit needs to be squashed or levered so that you know how to remove the old ones.

This is done by very gently levering up the very delicate clips you can see on the top edge (there are only two in the photo as mine has one broken off) and then pulling the top forward which will free it from clips at the bottom.

The one on the left is fairly easy but the one on the right will require a flexible driver. They are difficult to spot but they are there. Where the panel was, at the very front edge there are two torx. Remove the small panel immediately above the little nick-nack area at the from of the centre console by levering the front edge down with a flat-bladed screwdriver. Remove the four torx that hold in the radio cage (two are shown in the picture) and then remove the metal radio cage completely.

Push radio 'keys' into their holes and then using them to wiggle and gently pull the radio draw it out. Remove the right (driver) side of the 'transmission tunnel' - first remove the nut shown and then lever out the clips the same as on the passenger side using a flat bladed screwdriver. I also removed the nut shown in the picture as this gives usefull extra wiggle room. Remove the left (passenger) side of the 'transmission tunnel' by levering out the clips shown using a flat bladed screwdriver. This picture shows the piece you should remove. Then pull out the piece of plastic that it was holding in place. Remove the torx indicated in the picture. Under the glove-box in the passenger foot-well you'll find the bit in the picture. I've 'borrowed' a couple of photos from other excellent guides on this forum - I do hope their authors don't mind. You may be able to get away with a little less dismantling that I did but the whole job is awkward and the more wiggle room you can create the easier it gets. The main tools you will need are radio 'keys', a flat-bladed screwdriver, an inspection torch, a 10mm socket, T25 and T27 torx bits and a flexible torx driver. The looms that Fiat supply now have been modified so that the problem should never happen again. There are two different versions - one for cars without air-conditioning and one for cars that have it. Firstly make sure that you have the correct replacement wiring loom.
