Karl,

I remember your post on this procedure. Do you have any photos, or exact measurements of where to put the hole(s), angle of the spray tube, etc?

This fan was stuck and had melted the |switch. New switch, nothing happened. So I drilled the [3/8"] hole based on |staring at and measuring an old heater assembly on the bench. I hung a |small |LED headlamp over the upped edge to illuminate the bearing, and then I |delivered a dose of PB Blaster directly to the bearing via an extended |tube. |After an hour or so, I turned on the switch and thumped the dash hard a few |time with my fist, and voila! - it started running. I then delivered a few |small doses of Triflow to the bearing and that quieted things down to a |nice |purr. | |This is the story of the 'Mullendore Port'. Since then I've done a few more |that weren't stuck, but this shows that some stuck motors can in fact be |freed. Almost every stuck motor I have pulled has had only the exposed |bearing stuck.
