Trunk wiring all now good - it was a mess !(replaced!) Still unable to open the trunk manually (using the switch on the trunk handle). What else could be wrong ? Could the trunk catch be faulty ? Could it be linked to the door locking button on the key ? Help !!

Does it not open at all...?

The sensor pad in handle can fail..
But fob should still work

If the fob works then it's probably a crook micro-switch in the handle. I had one go at a very early stage but it was under warranty so I didn't tackle it. FIAT simply replaced the whole handle.

Key fob doesn't work at all.

Probably worth replacing the battery

then you have the chance the fob will open it..making access to tailgate easier

Does the central locking work? If you lock with the key does the passenger door lock?

I had a similar problem. I removed the boot backpanel and then unscrewed the whole of the long silver handle (4 screws I think) after unplugging the wiring . Once the silver handle is removed you can remove its plastic rear panel which is held in by plastic lugs. I used a flat screwdriver to prize it out. Once the back panel is removed i saw that my problem was a loose pivot pin. The actual boot handle pivots on two pins and one of them had worked loose . Although the boot handle still pivoted, it wasn't hitting the microswitch. I put the pin back in place and replaced the plastic back panel. I tested it before replacing it by reconnecting the wiring. Problem sorted. I then replaced everything in reverse order. The whole job took about 45 minutes and required no special tools or specialist knowledge or money. ( Allen key to remove boot fabric strap). Hope this helps.

Micro switch is working, boot latch is working - both tested off the car. Can someone tell me which fuse and/or which relay operates these parts.

Does any of the central locking work? Fuse 38 under dash 20a

Pic

Thanks John - is this the fuse box under the dash ? A bigger picture would be great.

yes that's the one in the cubby hole upside down

Better pic

If the central locking key button is not working (new key not coded yet) would that stop the trunk from opening manually ?

No power seems to be reaching the trunk switch and lock. Rear wiper working OK as is the heated window. Fuses all seem to be OK. Is there a relay somewhere ?

Do you have a boot light and is that working?

Check the hatch wiring.

Is it the convertible version? The boot stopped working on my daughters and I had to take several steps like open the roof, close roof, hold for a couple of seconds then voila! I'll find the instructions if it is
