How do i check to see if the fuse went out for my heat


Do you want to know why the blower doesn't work? If so, start at the underhood junction block and check the 30A BLO MOT maxi fuse which feeds power to the blower control module. Next, at the instrument panel junction block, check the 10A CSTR/SBM fuse and the 10A HVAC fuse. Both of these supply power to the heater and A/C programmer and the HVAC fuse also supplies power to the heater & A/C control. If all fuses are OK and everything is operating except the blower motor, check the voltage across its BLK and RD leads. The blower motor may be no good

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 .

Check the blower motor speed control resistor pack is ok.
(The resistor pack is usually located in the blower fan ducting in the air flow).
Check condition of electrical connection terminals on the blower motor circuit - these terminals pass considerable current and over time may fatigue overheat and loosen.
Check operation/replace any blower motor control relay,
Check the blower motor will run if +12v directly applied to the blower motor.
Check operation of the blower motor speed control switch is ok.
