2003 Astro - Front blower resistor is located just behind the coolant overflow and windshield washer tanks.
1) Pry/lift tank hold-down button center latches upwards (they are the small round buttons at center of hold-down. Grabbing the buttons with pliers works just fine!). When the latches are raised, lift hold down buttons clear.
NOTE: The coolant and washer tank plastic becomes brittle with time -- be careful!
2) Carefully remove coolant overflow hose from radiator.
3) Carefully raise coolant and washer tank from mounting location, be aware of connected washer hoses and pump wires. Tie back out of the way.
4) The blower resistor is the rectangular black box with the plug and wires.
5) Disconnect blower wires from motor ( violet and black).
6) Remove two small bolts securing resistor unit to air housing.
7) Gently remove resistor unit. (It has mastic sealing it to air housing)
8) Disconnect control wiring plug from resistor unit.
CONGRATS --- you are now holding your blower motor resistor unit!
