Hi all,
Hoping somebody has seen similar before or can point me in the right direction. Will try to explain as best as I can.
So my mum got in the car to drive to town and returned quite quickly saying there's a message on the dash saying along the lines of "hazard light system malfunctioning" - and sure enough the hazards were not working but the indicators were.
When she got back from town later I took a look and fuse 18 for the hazards was blown. I thought this was strange as the bulbs etc were all OK so changed the fuse (engine bay) and opened the door to test the hazards. Upon opening the door there was smoke quite visibly wafting out of the car and it was coming from the trim around the rear view mirror / 'behind' where the rain sensor is. At this point mum said there was also a smokey electrical burning smell she noticed earlier - so I assume the initial fuse blew at some point overnight or over the past couple of days (she hasn't driven the car for a few days).
I took all this trim apart and unplugged all the connections there (rain sensor, alarm switches panel, etc) and thought I'd plug everything back in one at a time and test (taking the fuse out each time I was plugging something in, then replacing it after).
All these connections are in a line in the 'module' by the headliner that is above the rearview mirror. It all works fine until I plug in what I'm going to refer to as the fifth cable (goes in the fifth connector from the drivers side). This cable seems to lead down the pillar and behind the glovebox somewhere. Note, it does NOT go into the unit I've put the blue star on in the picture, it goes behind it and downwards.
So anyway, it all works fine without this fifth cable, apart from the auto lights as you get a message saying auto lights not available - so it seems related to the auto light system somehow. When plugging this cable in, the HAZARD fuse pops again (I don't see how they're related) but the auto lights DO actually work fine with the cable in. So overall, with cables in / out the hazards do work (at one point) and the auto lights also work (at another point).
Since that time there was a lot of smoke there has not been any more. My plan was to take the trim off and see which part is smoking but that can't be done since it isn't smoking anymore - just popping the fuses straight away instead when I put that fifth cable in.
Autoglass changed the windscreen about 2 weeks ago - possibly unrelated though I thought I'd mention it as they had that area of the car apart for the rain sensor etc.
Anyone got any thoughts on this please?? I am a bit stuck on what to check next.
Any help will be appreciated.
Thanks!!
