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.

Electric fuel pump not working


Check the fuse and or fuel pump relay. Most relays are in underhood fuse box. If fuse and relay are good. Maybe pump is bad, check to see if there is power to the pump. After checking the fuel pump relay.

No power going to ignition control module, what would cause this?


Yes, the pink wire to the ICM and from the run/crank relay should have battery voltage in run or start. If not, check fuse 11, a 10 amp fuse in the Fuse Block-Underhood. Also check fuses 38- a 30 amp fuse supplying power to the run/crank relay, and fuse 9- a 10 amp fuse between the run/crank relay and the ECM. All of these fuses are in the underhood fuse block.
Fuse 38-the 30 amp fuse, the power feed for the run/crank relay- will be hot at all times. Fuses 9 and 11 will be hot in run or start. Check for power at the fuses. If the relay is not turning on and sending power to those fuses and to the ICM, and the ECM, (and to the injectors through fuse 16 - a 10 amp fuse), then work back to the ignition switch and the body control module. Wish I didn't have to say that, but yes, the BCM is between the ignition switch and the run/crank relay.
Good luck, Michael.

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.

No want to start,no light check engine on,


Maybe I can give a little help. Do you have the 4.0 liter straight six engine? This should apply as well if you have the V8 engine.

:...no check engine light...:With key on, does the light turn on? If not, it may not be getting power. Have to check that first, check all fuses in the under hood relay/fuse block. The check engine light should turn on with key in on position, just as an alert that the PCM is powered, and ready to work.

"...no electric to coil..." With key on, the dark green/black wire to the coil should have battery voltage. In that fuse/relay block will be a relay called an Automatic Shut Down relay (ASD relay). When the PCM turns this relay on, power is sent to the ignition coil on the green/black wire. The power feed for the ASD relay is fuse 2, a 20 amp fuse in the Power Distribution Center -the fuse/relay block under the hood.

So you have a couple of things to check: Make sure the PCM is powered. If it is, hold your finger lightly on the ASD relay while someone turns the key to on. You should feel it click on. If it does, but no power at the coil, check if fuse 2 is sending power to the relay, and check the green/black wire from relay to coil. If no relay action, possibly a bad relay, or the PCM is not turning the relay on.
Good luck. Let me know what you find.
