An update to this - I have not actually done anything about it, but after a heavy snowfall and a couple of short trips, the car had warmed enough to melt the snow. Then the three amigos (Park brake, TC and ABS lights) came on, I went over a bump and they switched off and the backlights came on for a moment.
Another bump and all was back to normal, so methinks that I need to get out there, sometime when the weather is better, and look at my earth connections... For now, I have just sprayed silicon on the earth connector and hope it does not get any worse. Mark PS. On the bright side, the snowy conditions meant I could check the ABS and TC, and both were working, even when the fault lights were on. An earth fault may be a pain to locate, but it is a damn sight cheaper than ABS problems!  |

I read the title of this thread and thought bulbs straight off, mostly because until May of last year I had no idea that the heater and fan speed panels on a TD5 illuminate...
 You can forgive me as I came from a 200tdi 90 and they didn't, so I did not know to look for them... Or at least that is my excuse and I am sticking to it. 
Anyway I lost all of the bulbs behind the dash in the space of 2 days driving in the Pyrenees and with all the blooming tunnels down there not having dash lights is frustrating to say the least. I am afraid the only advice I can give is to check every bulb, fuse and earth you can lay you hands on. It'll be some weird TD5 quirk... |

I had a very similar problem, the indy garage I use traced the fault to a faulty wire, that runs from a multi plug at the fuse box, up to the dash. They ran a new wire(with inline fuse) and its all good now.
The garage also said that the wires run from the multi plug, in behind the bulkhead and up to the dash and they are prone to breaking?! Not sure if this helps but it might be a pl;ace to start looking. |

Thanks to you both for the tips - there is heavy snow outside at the moment, but I think I can borrow a friend's heated workshop next Saturday, so I will start investigating then...

A big snow melt over the weekend added to the mystery of this one, as sometimes the backlights came on, but the fan did not work, sometimes the fan worked , but the windscreen wipers would only work when the fan was on full, sometimes the three brake lights appeared and other times not etc. As the car has dried out again, it is all going back to normal.
Obviously a wiring problem, but sadly for me, not one that is easily visible... The snow has been replaced by freezing rain and my friend with the workshop was having his monthly bender when we were supposed to be in there, so I am hoping for a break in the rain this weekend!  |

One month ago I have repaired wiring loom behind the dash of my 130 TD5 MY2000. Main problem was in headers located above fuse box- multiplugs used for connection of more than 2 wires. They have tiny contacts inside, some of them were coroded, some already burnt and plastic body of the header melted. I have removed the headers and just direct soldered the wires a heatshinked. Another problem was in realy sockets below the dash 2 of the 5 sockets had burnt contacts. So again replacement with new sockets.
After that disapeared some problems - not workin both dip and head lamps and not workind fuel pump. The work was easy - the dash was completely out of the car, because of repairing some rust on bulkhead. "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo  |

Dekuji vam MadTom.
It sounds like that little loom from the fusebox to the dash has caused a few problems so I will have a proper look through there when the weather is at least half way decent. How is the off roading down in Moravia? I spent a few years in Prague back in the 1990s, but was sadly lacking a Land Rover to explore with. Still had some wonderful times in some great countryside though, and would love to come back through in a Defender sometime! Cheers, Mark |

Offroading here is still possible, especially on some of our highways.
 And if you are interested in historical city, you can go for sure to Prague, or to my home city Olomouc. It is not so big, so you will need only your own legs to walk through, but also very nice.
For me offroaging is a nice way, how I can go out with my family. 2 years ago we spent some weeks in Monte Negro and Albania. It was very nice, and sometimes locals very a bit surprised, where we came from with 2 small (1 and 4 yeas old) children.
Here are some pictures: http://ok2mtm.rajce.idnes.cz/ And because Discovery2 asi a bit small for us, I'm rebuilding Defender 130 HCPU to a station wagon. "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo |

So I started poking around behind the dashboard, into the fusebox and under the car today. I have cleaned all the earths on the bulkhead, but noticed that disconnecting those did not stop the clock - are the dash instruments earthed somewhere else on the TD5?
I will clean up the ECU earth tomorrow, although it looks fine, but am also going to call in some expert help. The last car I had a good poke around the electrics of was a series three, which was much more manageable. Opening up behind the dash revealed what looked like thousands of wires, with all of the normal ones, plus the extra bits to keep headlights always on, and for the Webasto and the winch. I also found a few wires that were not connected to anything  and that two white wires coming off the ignition switch had melted the plastic of their terminals  . I cleaned and tightened the connections on the latter, but am admitting defeat for a DIY fix for the backlights and the other gremlins. A colleague has passed on the number of someone in the local offroad club, so I am going to use him to try and track down a decent auto electrician...
I will let everyone know when it's sorted and thanks fro your help! Mark |
