I think it was about a year ago when the front fan on my '91 GL started
squeaking worse and worse.  Finally it would run only on the highest
setting and finally blew the fuse.  I took a very small video camera
connected to a video monitor and attached it to a stiff wire bent in a
complex shape.  By feeding it in thru the front air intake I was able to
see the end of the heater fan motor and shaft end bearing..  I was able
to apply Tri-Flow lubricant thru a long tube by attaching the end of the
tube to another piece of bent wire.  I then used the wire to push on the
squirrel cage to get it broken loose, allowing it to start to turn again
when I turned on the switch.  As the lube worked its way into the
bearing, the fan gained speed and the squeaking eventually stopped.  I
also dabbed a little grease on the end of the shaft to keep moisture out
and provide some future lubrication.  The fan has been fine ever since.
  When I reported this on the list, most people thought I was crazy, but
I really didn't want to pull the dash if I could avoid it; so far so good.
You might be able to find my posts about it, if you search for my name
and video camera and heater fan.
  Harbor Freight sells a b&w security camera which works OK if you
shorten the focal length a little by taping a small plastic magnifying
glass across the lens.
It has built in IR LEDs for illumination which means you don't have to
manipulate a light in there too.  This camera is on sale most of the
time for $29.95.
