I think you're on the right track there (excuse the pun) Its really a case of getting hold of the loom and the dash and moving it slowly till you find the point it fails.
As you have mentioned the pcb I guess you are a hands on guy who may be able to bridge the track (if it is a track that has broken) thats at fault.
If you have a test meter check out each individual wire from the plug to the pcb in turn till you find the break.
Its possible that the plug or socket is at fault, again use the meter on resitance range to check it out
It may also be simply a case of using a suitable switch cleaner on the contacts (maplins do one)
