[DeTomaso] Heater blower fan

Chances are the brushes are worn. There are replacement fans that push more air at reasonable prices out there. Hall used to sell one that was a three speed, three winding motor and may still do so.

  Also, all fuses are good.

  Looking to the list for ideas on where to look for my problem...
  Background/Symptoms:
  Years ago my interior heater/AC blower fan stopped working.  I would
  turn the fan on high, and after a few minutes or more it would slow
  down and eventually stop.  Sometimes it would not come on at all.  I
  stopped using it altogether for a number of years.
  Last year I was planning to replace the heater/AC blower fan and
  started to remove the dash, but did not due to the size of the job and
  not having sufficient time before the next event/show I wanted to take
  the car to. So I re-secured the center console switch panel and
  buttoned everything up, then shortly afterward found the heater/AC
  blower fan was working perfectly again, consistently blowing high or
  low depending on the switch selection.  The fan was blowing steady like
  a new motor.  I mentioned this to another club member who told me the
  motors rarely actually go out and that the issue was most likely a
  contact somewhere else. So, I had the AC worked on and charged and the
  blower has worked fine for the last year or more.
  A week ago on the way home from the Niello Concours the heater/AC
  blower fan stopped working again. Regardless of the switch position,
  the fan motor does not come on.
  I've removed and replaced the wires from the switch to make sure they
  had good contact, but no change.
  I checked voltage at each post with the switch in the 'low' and 'high'
  positions and I'm getting 12v appropriately (or thereabouts - I don't
  remember the exact reading on the multimeter).
  I have a relay kit; could this be an issue with one of the relays?
  Where should I look next?
  Thanks!
  Garth
