Heater fan does not get power.


There are two fuses for the blower. One for the relay coil and the other for the relay power. One is a 5a in the interior fuse box. The other is a 40a in the engine compartment fuse box.

Heater fan not working


Smack it and see if it comes on. If it does then the motor brushes are bad. If it does not come on, check the fuses. If the fuses are ok, check the voltage on the plug to the motor.

2 fuses to check, Kevin: in the instrument panel fuse block, 20 amp fuse #12, Htr-A/C. In the under hood fuse block, Frt HVAC fuse, 30 amp.

The new resistor you put in, was it called a "Blower Motor Resistor and Relay Pack" ? It appears there is a relay there with the resistor, but appears to only be used with htr on high speed. However the low speed wiring is also routed through this relay. If it was the Pack you put in, guess that is not an issue.
In the Heater and A/C Control Module is the blower switch. The power in to the control module is a brown wire (from the #12 fuse in instr. panel). With key on should be hot. It appears the brown wire goes to the mode switch and then to the blower switch. Check for power in, and check continuity of both switches. Or check if blower switch has power to it, then check for continuity in it-it should have continuity in all speeds.
If all is good so far, you need to check if blower motor ground is good.
Here can be found a wiring diagram for your Astro. Look for heater controls under the system called "HVAC". Every wiring diagram and TSB for the Astro (or any make, model) can be found here:

Good luck.

Heater blower not blowing at any speed


check switch at contacts for continuity. Check heater blower fuse and relay If fuse is blown and new fuse blows right away there is a short to ground or power. (either in cab or under hood in power distribution box). Check wiring running to blower for possible short. Check blower.
