51 plate Renault Clio Short Circuit?

I own a 51 plate 1.4 16v Clio Privelege which I have owned from new and was an import sourced from Holland.

1. THE MAIN PROBLEM . A 15 amp fuse in the fuse holder in the end of the dashboard keeps blowing. This fuse is for the Rr wash and wipe, Ft wash only, reversing lights, heated rear windscreen, air circulating buttons next to the air con button. Sometimes when you try to replace the fuse it arcs as soon as you put the fuse near. Other times you can replace the fuse without a problem and all systems run fine from it simultaneously, turn engine on and off without it blowing, But then drive away and it sometimes it may blow.
I have stripped and lubricated the front and rear wash/wipe etc. But it still does it.

For about a year now the sun roof has leaked in heavy rain only and drips from the corner of the roof lining where it moulds around the drivers sun visor. ( dont know if related to electrical problem). Have read the other links re sunroof/ariel.

2. In the last three months the car has developed various faults.Starting with the on board computer becoming inaccurate with its readings. (this seems to have rectified itself). Read the other links.

3. Then the car has suffered intermittent starting problems. ( engine turns but does not fire at all). Starts after 2 -4 attempts then fine after. Have read the TDC links.

I am pulling out what hair I have left and would appreciate any help or advice from anyone with a similar problem?

Problem no.1 sounds like a wire has chafed through somewhere and is intermittently shorting to the chassis. I vaguely recall reading somewhere that it often happens on the loom under the car battery, so that might be a good place to start looking.

Does the fuse blow even when all the fed devices that can be turned off are turned off, or does it only fail when specific things are turned on? That might give an indication of where the fault lies. It could be the loom to the hatch lid if it only happens when the rear window or rear wiper is on.

Obviously you ultimately need to find out what's wrong, but when faced with a similar situation with the fog lights on my Mazda (I could find nothing wrong with the wiring) I swapped the fuse for a self-resetting circuit breaker. These trip out when the circuit is overloaded and cut back in after a timed delay. They do allow the circuit to overload, but only for very short periods and so the wiring doesn't get a chance to melt.

Unfortunately, they only go as high as 10 amps, and I doubt wiring two 7.5 amp ones in parallel would have the desired effect. But for the sake of 99p and a bit of soldering (you'd probably need to butcher an old blade fuse and solder the breaker to the pins) it could provide a good stopgap until you get to the bottom of the problem.

Sometimes when replacing the fuse it arcs straight away and sometimes it will allow you to put the fuse in and blow only when you turn the ignition on. Sometimes it will not blow untill you operate the rear wash wipe. or other function on that circuit.
When the fuse is in and okay you can operate all the functions simultaneously without blowing the fuse as was the last time with the fuse being okay with engine runnning/turning off/ starting again. All the functions operating at the same time and then trying various ones to try and blow the fuse and the fuse was fine for about 10 mins.
I said goodbye to my mate and drove 15 to 20 yds down the road and the fuse blew and you could smell it slightly. Not replaced since as I ran out of the mini fuses.

I have just fitted a piece of 15 amp fuse wire round the old fuse and tried everything again.
At this time all is okay. Drove round the block , still ok.It will blow later though I'm sure.
