Hi all,
I am having a few issues that I am trying to trace down and I could do with a little help from those who have probably had similar issues if anyone could lend me 5 mins of their time?
Briefly these issues are;
Heated rear screen will not switch on
Both front and rear fog lights will not switch on
Front headlamp power wash will not work
When I first started looking into this problem it became apparent that the sunroofs etc. were leaking a bit and the footwell carpets were damp underneath - I put a de-humidifier inside over a weekend and the problem circuits worked but soon failed again. This led me to believe that damp might be an issue.
I had the BCU and IDM out and there was some evidence of corrosion on some of the tracks. All dried out, cleaned off and then re-coated with conformable coating.
I have had the BCU tested by Richard at Callrova (excellent service and really really helpful on the phone and email!) and it all appears to work and test out OK.
IDM replaced from another car that appeared to work OK (it was from eBay and the chap who sold it to me said it was OK but it is secondhand and not actually verified as 100% but I have no reason to doubt at this time).
From speaking with Richard, reading several other threads on similar problems and my own first thoughts it looks like I need to verify that the earths are all good. From looking at the circuit diagrams one of the earth points keeps popping up that needs looking at - C0551 that apparently is to be found beneath the footwell carpet. I have just taken the carpet out (quite damp too) but the earth point is nowhere to be seen. Does anyone have a picture/location where it might be? Am I being daft by looking under the wrong side? My Disco is a RHD - is this earth point/header actually under the passenger side carpet does anyone know?
Many thanks to anyone who has read this far and can spare a little more time to point me in the right direction!
Cheers,
Matt
