I have a 1998 Discovery and like a few other people on here, am having cruisecontrol issues. I hear alot about these vaccum lines but I am unsure of all of their locations.. Can someone help me out with the spots?

Thanks!

 

One under the dash, hooking to a switch at the brake pedal area, the rest are by the cruise control unit.

 

Just to add a little more..... The one from the brake switch comes through the firewall to a tee junction. One goes to the diaphragm on the throttle assembly, and on goes up to the front to the cruise control unit. It is under the metal in front of your air box. Little difficult to get to, but if you replaced everything else, this is where to go next. I think there is a little jumper on the unit it's self.

 

Sorry...here is the follow up stupid question.. The cruise control unit is where? lol
thanks

 

If you look just in front of your air filter box, just to the left of the
jack you will see a round hole (2 1/2")with a vacuum line going
to a little air pump thats it a pain to get to.

 

Great - Ill check tonight
Thanks again
