1. I have a 2000 Buick Regal LS and the drivers side window (front left) will
not go down. Each of the other three windows go up and down just fine.

2. Same Car. When I attempt to use the high beam signal, it does not "click"
and stay in the on position. The high beams do comes on but does not stay on,
unless I hold the stalk back.

3. Same Car. The heat/defrost blower only works in the "high" position.

4. What do I need to do to fix these issues and can I do any of them my self.
I can do basic work (oil change CV Joints, Brakes, etc...

5. What costs should I expect to pay for parts and services.

Please advise.

Thank You.

Most likely you'll need to replace the motor.  Remove the door panel and
you'll have terrible, but servicable access to the motor.  You'll need to
drill out the rivets that hold the motor in.  Use screws and nuts or rivets
to install the new motor.  Make sure you use lock washers and loctite or
locknuts when you put the new motor in.  Dealer  price on a new  motor is
around $40 if my memory serves me correctly.  Don't trust that though -
check youself.  Likely you can get one out of a junk yard also.  The same
motor will be used throughout many years and many car models.

Sounds like the plastic piece under the steering wheel is broken.  You'll
need a steering wheel puller and the plate puller.  They cost around $20 in
the aftermarket however some stores like Auto Zone may have them to rent.
No idea on the parts cost.  Will likely be a dealer only item or junkyard.

Burnt out resister module located right next to the blower motor.  Just
bought one two days ago at my local Chevy dealer - $20 with tax.  Lay on
your back under the passenger side dash - remove the trim panels, you'll see
the resistor module sticking out of the heat duct near the blower motor.
Two screws hold it in.  One can be a son of a gun to get out on some cars.
One is all that is needed to put back in.

I could be just a bad connection.  Squirt some DeoxIT (www.caig.com) on
all the connectors.  Worked for me.  You can get it at RadioShack
(http://store.caig.com/s.nl/sc.15/category.295/it.I/id.28/.f)

It works wonders on all electrical connections in my cars and RV

When pulling the wheel is there anything to watch for with the air bags?

Yes - unplug the yellow plug under the steering column.  Best to go buy a
Haynes shop manual in your local parts store.  It will walk you through
these things better than trying to get step by step instructions over
usenet.

What Mike said, but first I'd check for power in and out of the switch and
at the motor connection.

For sure.  Sometimes those switches get rained on and can wear out
prematurely.

Does the car have 'one touch down' feature?

I had that feature in an earlier Buick.  POS burned out regularly,
BUT the module always failed in such a manner that the manual
down continued to work.

The module was pretty expensive, and it was always the SCR that
blew in my case.

Try pushing the stalk "forward" to make the high beams stay on.  Pulling it
towards you is for flashing the high beams temporarily.

I don't think the Regal works that way.  I had a '98 and it was not a
push/pull - not sure about the 2000.

According to the service manual this machine's high beams are activated by
pulling the stalk toward the driver until it clicks.

I stand corrected.

Question;
I have a Buick Century 2000, all Regal engine and front end, but Century
seating.
Did your lights ever go out, or flash on and off during the night with no one
in the car?
My drivers side door lock also unlocks all the time, but the other three will
stay locked, I call it my ghost.
Any ideas?
