Title: Speedo & Cruise Control
Post by Mottsy on Aug 22^nd, 2013, 1:19pm

Hi all.

Just back from my holiday in the new Forest, the old girl ran smoothly the only issue was occasionally the speedo would suddenly stop working for a few seconds or a couple of minutes and then spring back into life.
I also noted that while the speedo was u/s the cruise control would not switch on either?
it only happend a few times and was working fine on the drive home.
Any ideas?

Probably worth checking VSS. (Vehicle Speed Sensor)

I concur! VSS can be faulty but also give the contacts of the buttons a squirt of switch cleaner if all else fails

I had the same problem on my 2.0 along with the sidelights and panel lights and that was one of the pins on the headlight switch.

Thanks for the replies.

Can anyone tell me where to find the VSS, and if it can be repaired or do I need a new one?

It's for a 2.9 12v ultima estate.

Thanks

Tony

Had the same problem last year with a 24v. In the event it turned out the the VSS was ok but it was the wiring to it which was faulty- the old crumbling insulation problem !
