[DML] What would cause my blower fan (A/C) to quit after 1 minute?

["Doug Menkhaus" <dmenkhaus@xxxxxxxx>]

My blower motor (under the dashboard - Heat and A/C fan) will not stay on ,
on speeds 3 and 4.  My car has recently come out of a 20 year hibernation.
If I turn the fan on speeds 1 or 2, it works perfectly.  If I select 3 or 4
however, it only runs for a minute or two then quits.  I can turn it to 1 or
2, and it works fine.  A few minutes later, I can turn it back to 3 or 4,
and the fan blows again for a few minutes, then shuts down again.  If I
leave the fan on in position 3 or 4, it will quit after a few minutes, but
then a few minutes, come back on.  

I replaced both the Speed 3 and the Speed 4 relays, no change.  Seems like
some sort of thermal cutout is happening, but where?

Doogie
