Brake Pad Wear Light

[mboucher70 hotmail.com]

Exactly, I tried jumpering both left and right at the wheelwells but the 
light stays on.

I've since done some digging online and found that the auto-check computer 
is probably right behind the instrument cluster.  I had removed the 
instrument cluster years ago to fix the known "bobbing speedometer" problem 
(cracked solder joint).  I recall that removing the instrument cluster was a 
painful time consuming repair so looking for other places to check before 
going there.

Looking through the Bentley wiring diagrams now :-(

You can TRY jumpering at the connection at the wheelwells, but often the 
issue is in the wiring farther up the system. Some cars, the jumpering works 
best at the instrument cluster.
