How can you tell it's winter?  : >
Driving my kid home last night, as the temp started to drop from
unseasonable highs, my front heater fan stopped blowing. Question is,
is it the fan motor or the switch that failed?

With the rear fan blowing on high, I can hear it slow down
incrementally as I advance the front fan switch from 1, to 2, to 3.
I'm guessing this means the front switch is fine and the motor is
seized.  Right?

If so I'm looking at a front fan R& R. Any web postings on the
procedure?
Anything else that should be looked at while I have the dash out?
Many thanks for the wisdom
Cheers
