Thanks again Hyundaitech,
 This is the 3rd electrical issue I've had  come up on this XG this
year -about 65,000 mi. (103,000km) on it . Given where we live -middle of
nowhere- seriously to get to a dealer that knows anything about this
vehicle, I've got at least a 6 hour drive through high mountain passes that
may or may not be open due to our Winter conditions here in the Interior of
British Columbia. Usually that means a minimum of one overnight at a motel,
if I'm lucky. Now let me tell you the auto repair is cheap relative to the
shopping my wife will do in the Mall while we wait for the car to be fixed.
That's why I try to repair it out in the SNOW, so thanks again for all your
help.
But I have to say my 1990 beat-up old Ford F250 with rust holes in the
floor for the melted snow to drain out, looks better & better to me. And the
heater works just fine! The only thing a bit 'cranky' is the driver.

PS: Had all these funny shiny wet spots about 2" circles/ ellipses behind a
rear wheel the other morning. Took a bit of detective work, but the snow
tracks told the story. Seems deer must have been licking the dried salt
(from the slippery roads) off the lower rear fender!
