Thanks for the info guys - its nice to know the history.

The fan never seemed to move much air, even at the highest setting. Now that its out I'm going to see if it was a function of the switch or the motor. (or both)

When these things were running on high, how would you compare the air speed to a modern fan in todays car? I imagine the 6V might would affect it right off - but I have no baseline to compare a good running motor too!
