Thanks, Jim. You are a blessing!
I looked carefully, and sure enough, the plastic clip has a broken tang. I
swear that it's not of my doing -- this vehicle had a previous owner for
about a year before it got in these loving hands. In the meantime the
ding-dong 'brush' is held by electrician's tape wrapped around the cylinder
housing. So far, so good -- dinging when it should and not donging when it
should not... For the benefit of those who may need to pull this little
'brush' out: make sure to remove the lock cylinder first. There is no way to
pull this thing out without breaking it, if the cylinder is still in place!
If I may vent a bit, two other electrical problems are driving me crazy:
1) The CC servo has an electrical failure. Nothing wrong with the servo
itself, just some logic on the attached circuit board (it won't even
self-diagnose). Why should I toss a perfectly good motor, clutch, gears --
whatever is in that box -- because of a failure in the circuit board?
2) Even more annoying. The PCM has an intermittent short to ground on the
ACT sense line. With a decent schematic I would probably be able to find the
solder splash or a piece of debris that's causing it, but of course, these
schematics don't exist in the public domain. So now the PCM has to go. But
it doesn't end there. In this model the PATS relies on matching code with
the PCM. So not only do I need a new PCM, but it also has to be installed
and programmed by the dealer. Something is telling me that I will also be
stuck with a fee for diagnosing the DCT that started all this: testing the
ACT sensor, harness, connectors, etc. And why would they take my word for it
