SOURCE: I have a 2001 Chevy

Replace the blower motor resistor. Remove the shroud below glove box, 2 screws and a snap-pop fitting. Be careful of the courtesy light. Remove the blower moter and disconnect the purple/black power connector to it - - you'll need this extra room to work with. 2 more screws, same size, 6.5mm on mine, 7or 8mm on some others, that holds the blower motor resistor in place. This replacement part is less than 40 bones at most parts store. Unplug, replace, re-install, test and you're on your way with about 2 hours of slow paced effort in your own driveway. Typical cost at a garage - up to $400, what a sham.

SOURCE: blower motor doesn't work and has no power to it

Check the blower multispeed control resistor pack is not faulty.
The resistor pack is usually located in the air ducting, in the blower fan airflow.
Basically, +12v power is supplied (via fuse) to the fan speed control switch, which then passes via the selected speed control resistor, to the fan motor. Often a interface relay is used to switch the blower motor high current.

Heater does not work

Check heater fuse.
If fuse good - could be a failure of the blower fan motor or blower control switch.
If fuse bad - bad blower fan motor could have blown the fuse.
DO: check fuse, then blower motor.
Pricing: new blower motor: Duralast PM270 $43.99
new heater control switch: Duralast SW229 $46.99 (without
A/C).
I'd expect your blower resistor to be good - when they fail, the blower only will work on HIGH setting.

My blower is not working for my heater

first off! check the heater blower fuse in the fuse box if it is good? then check the power lead to the heater motor itself as well as the ground wire to it to insure proper connection if that all checks out satifactory then take a jumper wire from the B+ side of the battery straight to the heater motor if the motor fails to run then change the motor if it does run? then check / change the blower motor relay
