<VV> '65 Corvair heater "FAN" selector has 4 settings?

[J. R. Read]

BTW...   If you have a metal "squirrel cage" attached to the blower motor 
and were having a squeal sound - that typically comes from the fan (squirrel 
cage) slipping on the part that holds the fan to the shaft from the motor. 
Greasing it might quiet it for a while (don't know - never tried that), but 
the fan is probably running slower than the motor.  Eventually, the fan will 
likely stop running - or nearly so - no matter how fast the motor is 
running.

You might try to peg the fan to that metal center piece in some way so that 
it cannot slip.

Even if the fan motor is not running you will still receive some "warmish" 
air through the heat system from the top side of the engine as well as a 
portion of the air pushed by the engine fan.  Probably enough for around 
town driving, but probably not enough for the highway.  Push the HEAT lever 
forward without pushing the fan lever forward for a test run at this.

Later, JR
