M&S Posted May 22, 2010 Share Posted May 22, 2010 I know that the TD5 has a square switch that disables the rear windows. Does the 300tdi? If so, maybe that's faulty? Quote Link to comment Share on other sites More sharing options...
ches Posted May 22, 2010 Share Posted May 22, 2010 have a look here seems to be the most common fault. http://www.discoweb.org/window/index.htm Quote Link to comment Share on other sites More sharing options...
mudmagnet Posted May 22, 2010 Author Share Posted May 22, 2010 cheers will have a look at that and no its not the switch that disables the rear windows as they wont work from the front switches either Quote Link to comment Share on other sites More sharing options...
gripper Posted May 22, 2010 Share Posted May 22, 2010 the link won't work on mine but i presume it's for the electric window relay box underneath the dash on the passenger side, these are common for dry joints inside but mine seems to have a dodgy wire going into it as if i move the wires the rears work again.

Niamh Posted May 23, 2010 Share Posted May 23, 2010 Just been trying to fix one here, no sign of any bad joints and everything was working fine with the board out of the housing... put everything back and no rear windows again Niamh Quote Link to comment Share on other sites More sharing options...
gripper Posted May 23, 2010 Share Posted May 23, 2010 loose wire like mine, intermittent not working till i move it. Quote Link to comment Share on other sites More sharing options...
Niamh Posted May 23, 2010 Share Posted May 23, 2010 Could well be, I'll strip everything back down again at some point Niamh Quote Link to comment Share on other sites More sharing options...
scrumps Posted May 26, 2010 Share Posted May 26, 2010 Could well be, I'll strip everything back down again at some point Niamh Hi, My mate hadd a similar snag on his N-reg 300TDi Disco. Turned out to be the swithces were corroded inside and full of crub/fuff. Try swapping the front switches to the rear in the centre console and see if they work. With (very) careful use of a small screwdriver you can open up the swithces and clean them (but watch for springs and bits whizzing past your ear). I have heard of people opening them up inside palstic bags to catch all the bits before now. Hope this helps. Scrumps Quote Link to comment Share on other sites More sharing options...
Niamh Posted May 27, 2010 Share Posted May 27, 2010 That doesn't explain why they worked with the control board outside it's box but not when reassembled. Niamh Quote Link to comment Share on other sites More sharing options...

mudmagnet Posted May 30, 2010 Author Share Posted May 30, 2010 i tried to remove the window ECU but i cant get the wiring plug out of the ecu, there are 2 plugs the top one came out ok but the bottom one wont come out at all, so i cant get to remove the ecu apart from setting fire to it what can i do Quote Link to comment Share on other sites More sharing options...
gripper Posted May 31, 2010 Share Posted May 31, 2010 have the 2 plugs got a release catch on them? it may have broken on one allowing it to come out without the catch being pushed in, they can be awkward to push so use a screwdriver if you can reach it.

mudmagnet Posted May 31, 2010 Author Share Posted May 31, 2010 cant see a catch and the one that comes out didnt have a catch and theres no room to move so maybe i will just have to live with it it looks easy in the pics but it isnt Quote Link to comment Share on other sites More sharing options...
