Suzierabbit Posted April 12, 2015 Share Posted April 12, 2015 I have just bought a ford fiesta zetec econetic tdci 2014 and I have noticed built into the rear view mirror casing there are what look like sensors and also on the dashboard there is a small ball. I have looked throughout my manual and there is nothing in there about these. The salesman at the Ford showroom had no idea also. I believe they might have something to do with automatic headlights/window screen wipers. Can anyone help? Quote Link to comment Share on other sites More sharing options...
btmaldon Posted April 12, 2015 Share Posted April 12, 2015 Is there an Auto setting on the headlight switch? Have you tried the first position on the windscreen wipers to see if they wipe on intermittent or require water on the screen? Quote Link to comment Share on other sites More sharing options...
Figgis41 Posted April 12, 2015 Share Posted April 12, 2015 Hi, on the back of the mirrow case is a light filter and on the front mirror bit its self is a sensor, these are for the automatic lights and the anti glare features. If you then look from the outside through the screen at the rearview mirror holder you will also see another sensor for the automatic wipers. Hope this helps.

Celticfan Posted April 13, 2015 Share Posted April 13, 2015 Great salesman who doesn't know about the car he's selling. I did sales for a while( I had been in the Electronic Security industry for a long time, hated every minute but wanted to give it a try and I made sure I knew as much as I could about the products) I seem to recall that the 'ball' on the dash is something to do wiith climate control. I'm not definite about that...but then again I'm not trying to sell a very expensive piece of kit! Quote Link to comment Share on other sites More sharing options...
iantt Posted April 13, 2015 Share Posted April 13, 2015 the ball on dash is the sun load sensor , thats for the air con. if you do have autowipers and autolights , then there is 1 sensor fitted that does both functions, and that located below mirror attatched to the screen Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted April 21, 2015 Share Posted April 21, 2015 The ball is the sensor for the auto temperature on the climate control as Ian said Quote Link to comment Share on other sites More sharing options...
