I will have to take it apart still. The wires were so corroded that they were green inside the entire length of the power cord. Not a good thing.
But I did finally find the manual
Doesn’t say it outright but does seem to indicate that the plastic blower fan should be able to come off. When I’m down at the VHS which will be soon but not till after the snowfall I’ll try to see if I can remove it without breaking it. If that fails its off to the junk yard.
But thank you for looking.
