neil82 Posted August 27, 2013 Report Share Posted August 27, 2013 think the fact that the high level lamp works rules out the switch, time to get the multi meter out and check if any voltage is reaching the bulb holders Quote Link to comment Share on other sites More sharing options...

Mike737 Posted August 27, 2013 Report Share Posted August 27, 2013 Bad earth maybe? On my Tranny, the earth wire had corroded inside the back door. Cut out the bad bit and graft in a new piece, right as rain. Quote Link to comment Share on other sites More sharing options...
neil82 Posted August 27, 2013 Report Share Posted August 27, 2013 take bulbs out, check for voltage between bulbholder and good earth, if 12v put bulbs back and check again, if not 12v then most likely ****ty connection or part broken wire, if 12v then most likely earth fault Quote Link to comment Share on other sites More sharing options...
