By the way, I tried the same treatment (spraying with questionable
chemical from Radio Shack) with limited success.  Seems a little better,
but still problematic.

But did I spray the correct contacts?  I was too lazy to look at the
Bentley, but the ones I did were under the plastic cover, near the freon
reservoir on the  passenger side. (The instructions on Chris Miller's
page say they're on the driver side).

If it's just a noisy pot, it might be possible to just disassemble and
clean, or perhaps bend the wiper a little.

Great sleuthing, Phil!
