karlenest170 Posted May 3, 2009 Share Posted May 3, 2009 I brought my ST170 in Dec and im starting to get annoyed. The dash light flashed on and off every now and then. Once it stopped working all together so had to drive by just the bright orange needles guessing my speed. Is this something to do with the dimmer switch as thats what ford said it was. Any help would be great Thanks K Quote Link to comment Share on other sites More sharing options...
SierraYankee99 Posted May 3, 2009 Share Posted May 3, 2009 Yeah I seem to remember it is. They are known for flickering too which can be cured by just lowering the dimmer slightly. Sounds like yours has packed in altogether though. Quote Link to comment Share on other sites More sharing options...
Whelk8891 Posted May 4, 2009 Share Posted May 4, 2009 It may just be dirty. Get some Servisol switch cleaner (about £4 from Maplins) and give the potentiometer a good clean with that. Spray some inside it then turn the dial up/down a load of times to work it through. Do not use WD40! Quote Link to comment Share on other sites More sharing options...
