Allan,

Larry Alofs rigged a small tv camera and a lube dispensing tube with
reported success. On 10/19/05 he posted:
" 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."
