I own a 2002 A4 1.8 T. The problem i have is the mirrors don't work, the windows don't work and the interior light stays on, as well, the central door lock dosn't lock or unlock the drivers door (but it will control the others). Can anyone help resolve this issue (and give me a breif discription of the repair along with the part number i need)? I hope tofix this myself to avoid a costly repair. Cheers; thanks, in advance.
