Heater &air wont work

I have a 1996 Chevy astro van LS The heater motor wont run. I get power to the relay module .I can close the relay & heater will blow.I am concerned it might be the main module not sending out power to relay in main fuse relay module. air wont work either. coils on both relays ok aprox 84 ohms. Thank You Pete.

Resistor , check it out. Conect power to the motor direct , see if it rotates. Hot wire it with a fuse and a swich through the resistor for different speeds. It will be manual not auto unless you want to change the module. Re calibrate the vent doors , and do a diagnostic if you have tha auto modul . Vitally

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.

1996 astro chevy van heater use to work on low and med but wont work at all now.


The blower resistor has gone bad which is why you lost blower speeds.This may have been caused by the blower motor drawing too much power. At this point I would verify that no fuses burned out and then check the pigtail plugs going to the resistor and blower motor to make sure the connectors and connections are not melted or wiring is frayed. These connectors are located in the engine compartment on the passenger side. After checking this and if everything appears ok then the blower motor itself has probably gone bad and needs replaced. I would also replace the blower motor resistor as well. If the connectors appear damaged replace or repair as needed .

I have a 93 chevy astro van and the blower fan keeps blowing fuses. the fan checks out good, can't locate the relay which I think may be bad. as I can unplug fan and still blows fusew.


The relay is not your problem or it would blow wheather or not the heater motor was plugged in or not if it was shorted,you need a new heater motor.
