Hi all, i've been having a few electrical issues with the footwell fusebox since buying my car and its been getting most annoying. Had an electrician remove cowboy wiring and thought it was sorted. Then last night the problem came back, i've spent allday on it today and finally discoverd the problem. It played up again after i washed the car so checked behind the fusebox and sure enough it was soaking wet, i pulled out plugs, relays ect.. and all soaking wet. The reason, if you remove the T roof panel you've got 2 drain holes one runs down a plastic pipe through the A post the other down the B post. The one running down the A post (windscreen pillar) had parted company with the rubber elbow joint just above the fusebox, so all the rain water was in effect hosed over the fusebox. Been out there allday with a hairdryer trying to dry it out, but i think i leave the battery disconected for tonight. May be worth checking your cars folks. By the way on the fusebox under the fuses there is a small black plug with a loop of wire coming out and going back into it, can anyone tell me what this is for. Thanks.

Sorry can't help with the answer, but yep on the fuse box. Jeff covered it before in this thread.

Wow, pretty common then, bad design that. On mine it does seem as if the plastic pipe had shrunk cause it would'nt even reach the rubber elbow, so replaced the lot.

I also have electrical problems which I'm putting down to the same thing but yet to pull the fuse box out.

 

I have no interior lights, opening the passenger door turns off the clock, the clock comes back on when the door is closed... The door ajar light comes on and off randomly, sometimes really faint as if a poor connection (water) is being made. The alarm doesn't know what to make of it all!

 

I really need to fix this soon, but its been so cold, dark and wet.

Yeah sounds familier, My clock and heater setting allways stayed on. Put your head down into the footwell, see if you can hear anything, mine was fizzing, electric and water:scared: Seriously though your car could go up in flames.
