10000rpm Posted December 16, 2012 Share Posted December 16, 2012 Maybe check the connection to it the slider is not sticking is it? Quote Link to comment Share on other sites More sharing options...
WilkesyMB6 Posted December 17, 2012 Share Posted December 17, 2012 Yes its those switches on the door like you said. One of mine stopped working so I took it off and put it back on and it was fine after that. So it may be worth a try. Quote Link to comment Share on other sites More sharing options...
Civicsport5 Posted December 17, 2012 Author Share Posted December 17, 2012 Will try that however just need to work out which one it is that's causing the light to come on! Quote Link to comment Share on other sites More sharing options...
Mr Brown Posted December 18, 2012 Share Posted December 18, 2012 just take all four off one by one and clean up the screw hole after removing as door switches use that as the earth and it may not be making conection Quote Link to comment Share on other sites More sharing options...
WilkesyMB6 Posted December 18, 2012 Share Posted December 18, 2012 It won't take long as I think there is only 2 screws per switch. Quote Link to comment Share on other sites More sharing options...
Karjis Posted January 22, 2013 Share Posted January 22, 2013 It won't take long as I think there is only 2 screws per switch.Or was it 1 screw and plastic pin on the other end? Quote Link to comment Share on other sites More sharing options...

I need to fix it really as its annoying!Just open and clean the switch, but don't lose the returning spring Take fine sandpaper (400-800, whatever) to clean that green oxidised stuff away from those contacts so contacts are clear metal again. All black and greenish stuff are things you wan't to get rid of. After cleaning, good coat of grease made for electric connections to protect those contacts from moisture and it should be fine for years again.

ryan.. Posted January 22, 2013 Share Posted January 22, 2013 Mines used to flicker on/off or sometimes stay on constantly. I traced it to the drivers rear door and the problem was the catch which the door clicks onto was loose somehow. Adjusted it and tightened the bolts and all sorted Quote Link to comment Share on other sites More sharing options...
