  • Condensation in rear lights

    The rear lights on my facelift have condensation in them, the passenger rear light is by far the worst. I have dried the rear lights out and put then back in the car and after coming back home I thought I would have a look and the whole passenger rear cluster is dripping with condensation again. Anyone else have this problem? Or have sorted this problem? Any help would be appreciated.

    I use to get slight condensation in both front and rear lights on my facelift and my current GS is no different. It seems to be a trait of the insignia in certain weather conditions and is even mentioned in the manual. Dripping condensation is another thing though. That could be caused by a leak.

    One way to test for a leak if there is no physical evidence is take off the light and blow a mouth full of vape into it and see if it escapes from any hidden cracks or bad seals.

    If you can't find any leaks try dropping a few silica packs inside to help absorb any moisture https://rover.ebay.com/rover/0/0/0?m...2F352243372667

      Drill a 2mm hole in bottom of lens in an unobtrusive position and somewhere water can drain.

        Just to add, if lights are full of water it will run down into your drill so be ready to move drill quick.

          The lights may look dry but there could still be a bit of damp hidden away and that will recondense when sealed back up. At least that's what happened to me.

          As someone suggested, some silica packs inside for a week or so will absorb any remaining moisture but that's assuming you dont have a continuining leak.

          The main bit to look out for is the seal. Mine had a split in it but I have repaired it with some super glue and a dab of silicone. All is fine for me now.

            Dried the lights out and drilled a few small holes at the bottom of the light and no condensation for a few days so looks like it has worked. Cheers guys
