the front heater blower motor on my vanagon is starting to squeal
intermittantly..   the warning cries of its iminent death..   which involves the dreaded
dash removal (dont want to tackle this in the middle of winter)..   is there
any way the motor can be lubricated to extend its life a little more...without
removing the whole dash?   any trick lubrication methods or lube points?  the
motor still works, just squeals once in a while..

any ideas appreciated..
