As was mentioned, the GP harnesses are a problem. Probably replaced/repaired 
25 of them int he year I worked for the local independent.

The GP circuit looks for a resistance difference between the two sides (each 
side of the harness feeds two GP's). If the harness is wotherwise in good 
condition, and the GP's check out, I've also hooked the two circuits 
together, and this causes the CEL circuit to see the same resistance across 
both GP circuits.

On the trunk, if the bottone doesn't work, a lot of times it's the button 
itself. Very common on these, along with the rear latch plastic breaking.
