Ummm.. okay, here come some ignorant newbie questions.  I've 
ensured that the Multimeter was working properly.  I've taken the 
reading between the #8 terminal of the CC control unit and the 
control unit harness: found no reading.  The Book of Bentley then 
tells me to repair the ground.  I have made a visual inspection of 
the control unit harness and found the connections to be clean.  The 
wire from the ground of the control unit harness leads to a second 
plastic housing which was clipped to the underside of the central 
console.  Finally, a single brown wire (female) leads from this 
housing and goes to a connection (male) next to the control housing 
(is this making any sense?).    

Ignorant newbie question #1

Is this brown wire part of the ground?  Will its being connected 
affect the ground test?

Ignorant newbie question #2

The second plastic housing was clipped to the side of the central 
console.  Will its being "unclipped" while I was testing affect the 
ground? (My guess is not, as it is encased in plastic, but whadda I 
know.)

Ignorant newbie question #3

Assuming that all these things make no difference and it IS the 
ground that is causing the CC malfunction.  How would I use the 
multimeter to test the cable's continuity.  

TIA

Jon
