What will cause the ac and heat to quit working on a 97 blazer?

Asked by Aug 15, 2015 at 06:11 PM about the 1997 Chevrolet Blazer 2 Door 4WD

Question type: Maintenance & Repair

Nothing is getting blown in the car and the
blower motor is not working. Fuses are
good. The switch to turn it on is working,
same with the control settings. I unplugged
the wires running to the blower motor and
and it tested just over 12V. Hooked up a
new blower motor and still nothing. Anyone
have any answers?
