Truck Repair: blower motor not working, resistor pack, heater blower

Question
I have a 1991 Chevy s-10 pickup  with blower motor problems. I "hot wired" the blower motor it worked, replaced the switch, replaced the relay but the motor will not work .  I am stumped ...do you have any ideas before i put the truck in the shop?

Answer
Hi Ray,
There is a resistor pack that is used for all speeds except hi. The resistor pack is located in the heater blower housing, right close to the relays on the firewall.
But if it doesn't work in any selected speed, it is probably a fuse, marked hvac
