Cruise Control

Hi Andrew
I ask the question recently, as I have intermitant cruise control, someone posted, try kicking the brake pedal, to see if it then works, tried that, it seems to work each time I do this, so it appears to be something to do with the pedal switch, any Ideas, could it just want lubing, or maybe the contacts cleaned, are these the same on all Scorpios, would it be worth trying a second hand switch.
Thanks Colin

Have you tried pulling the switch plunger all the way out ?

Hi Jonnycab
Just taken the switch out of the car, the plunger is spring loaded to keep the plunger out, this seems ok, I have lubed the stem of the plunger with a small amount of silicon grease, tried a meter across the contacts on the switch, they make ok when pressed, also cleaned the plug contacts on the switch
Will try for a run tomorrow to see if its done ant good.
Thanks for the reply
Colin

Hi Colin,
We see a lot of this on cars nowadays as the brake switches can cause all sorts of problems as transmission computers now have an input from them !
Anyway....sometimes these brake switches are just too darn sensitive and a little adjustment can help.
What I mean is .... Its designed to switch when you apply the brakes, but sometimes they are fitted / adjusted so if you breath on the brake pedal they will switch, so there may well be nothing wrong with your switch.
I cant remember if the Scorpio ones are "officially adjustable" if you see what I mean, if not its usually a matter of some gentle persuasion on the bracket to make it less sensitive. 
HTH

Hi Colin....not sure if you know, but the plunger has notches on it, to keep it out at different lengths, that's why I suggested pulling it all the way out.
If you haven't already done so, pull the plunger quite hard & it should come out all the way (about 2 inches), then put it back in the car & let the pedal set the right length
Sorry if I've told you something you already know, but it was unclear whether or not you had pulled the plunger out to it's limit

Hi All
Have taken the car for a short test run this morning, the cruise control worked every time, normally when I have taken it out of cruise with the brake pedal it will not fire up again, I took it out 3-4 times, then it reset as it should, lets hope thats the end of this problem, as I have a long run to France very soon, a good deal of motorway.
Colin
