It can be faulty blower motor relay or its issue with blower motor resistor.

Get the blower motor re-inspected. If its faulty it has to be replaced.

Replace your resistor if you haven't already. I had the same issue with mine, it only worked on high.

I don't know what you mean by temp module but i'am gessing the switch on the dash, but to me it sounds like the resister is bad, i believe its located under the hood on the air box if not than chk. under the dash by the heater motor, i have seen the wires burn that plug into it when they go bad, thats what makes the blower run and also regulates the speeds of the blower motor.

2005 Chevy Colorado LS 5.3L Blower motor iOS not working. Replaced the resistor because that was burnt out but it didn’t fix the issue. Figured out the connector only gets power at the brown wire and...

The top wire at blower motor is voltage, the bottom wire is ground. So brown wire is voltage, orange wire is ground. So, the resistors, havc control, on and off and speeds are controlled on the ground circuit. Generally if ground is good, no voltage or very little on the ground circuit, because the component is using the voltage. The wire connector for your blower motor is it any good? You could remove blower motor, use jumper wires off battery for voltage and ground, the blower motor should run up a storm. It wouldn't hurt to use inline fuse, just incase.
I looked at info for 3.5L, my info didn't show 5.3L?

2003 trailblazer blower not working

Are you saying the blower motor would run intermittently and then just stopped working? My first thought is faulty blower motor, I've seen faulty blower motors that would run intermittently. Any motor that uses brushes, you can tap on the motor to see if it will start working, that is a sign of bad motor brushes, replace the blower motor. There could be other issues?
Did you check the blower fuse, not only check the fuse, check the fuse circuit for voltage, use a test light. Check for applicable hvac trouble codes. With hvac on, check for voltage and ground at blower motor wiring connector, if both are good and no blower action, suspect the blower motor.

The ventilation fan for heat/ac is not working. The fuses all seem the be ok. Any thing else to look for

Did you check the proper fuses for voltage? Some fuses are hot all the time, some go hot with the key on. Even if fuses are good, if no voltage the circuit is still dead. I guess your talking about the blower motor? Can you hear it running? I don't know if you auto hvac or manual hvac? I don't know if your talking about front or rear blower motor?
Get at the blower motor, if two wire connector, that should be voltage and ground. Turn on the hvac controls, check for voltage and ground at the blower motor connector. If good voltage and ground with no blower action, suspect the blower motor.

It is possible to use jumper wires from the battery for voltage and ground to blower motor connector, just for testing to see if blower motor will run, use an inline fuse, just in case.
If you want wiring diagram, I need more info.

2004. Why is the blower motor not receiving power?

The blower motor relay in the auxiliary junction box under the hood is good ? All relays ? only one controls the blower motor ! The electronic automatic temperature control module turns it on by supplying a ground inside the module ! The 30 amp fuse for the blower motor is located in the under hood auxiliary junction box ! At the relay socket test for battery voltage at pins 30 an 86 ,power form 30amp fuse ! The other two pins 85 an 87 ,85 is circuit to the electronic temperature control module . You could test this part of the circuit too , with a test light or volt meter . But if no voltage to the blower motor ,could be the electronic temperature control module is bad !

I turned on the ac and the light does not work, the vents are not blowing and the car is running hot. I have a saturn SL 1996

First check the 15 amp HVAC fuse located in the main fuse block inside the car on the passenger side of the center console, under a cover. If the fuse is good, then the problem may either be the HVAC blower switch (which is the fan blower selector switch), the fan blower motor resistor, or the fan blower motor. An auto repair manual will explain and illustrate for you the steps on how to check each of these components.

Even after pushing the ac light switch on, the fan blower selector switch has to be turned on as well (working) because it provides an electrical path to the positive side of the battery to complete the circuit and turn the ac light on. What the ac light switch does is provide the electrical path for the ac compressor clutch to come on through the ac control relay which is controlled by the car's PCM(computer) when you want ac, but the ac light switch still needs to run through the fan blower selector switch to receive its power. You can turn on the fan without the ac light switch because it gets its ground path(negative) from the blower motor. So the blower motor has to work in order to provide a ground path for the fan blower selector switch to be functional. You could have a faulty blower motor which is why no air blows through the vents. The fan blower motor is located inside the car on the passenger side underneath the dash at the bottom end of the glove compartment box. You'll see it. It's right above where a person rests their feet on the floor. Therefore, if your 15 amp HVAC fuse is good, check to see if you have voltage at the blower motor connector. Unclip the connector and with the ignition on and the fan blower switch moved to any one of the first 3 selections, check for voltage using a multimeter. The voltage will vary because there is a blower motor resistor. Voltage should be higher on setting 3 than 1. If you do have voltage at the blower motor connector, check for a faulty blower motor. The auto repair manual will tell you how to do it using jumper wires.

It's normal that your car is running hot because the radiator fan works in conjunction with your ac compressor. If the ac is on, the radiator fan will be on and therefore the engine coolant temperature will stay in it's normal operating range. If the ac is off, the radiator fan will stay off as well and the engine coolant temperature gauge will begin to rise and show pretty hot (especially at idle). It will do this up until a certain degree then the radiator fan should turn on thermostatically and stabilize the temperature. It's scary and I know what your saying because it does that to my car if my ac isn't on. Don't worry it won't overheat.

Hi I will try and help you if i can.
Yes, there will be a resistor pack that controls the speed of the blower motor.
Usually on a 4 speed motor there will be three resistors.
When 4 speed is selected the motor gets full 12volts ( no resistors used )
When 3 speed is selected the motor gets its Voltage via 1 resistor ( reducing the speed )
When 2 speed is selected the motor gets its Voltage via 2 resistors ( reducing speed even more )
When 1 speed is selected the motor gets its Voltage via 3 resistors ( giving the lowest speed ).
Usually when the resistor pack burns out the motor will work but only on no.4 speed which does not use the resistors.
So i think your problem might be the control switch.
Ihope i have been of some help to you.

The blower motor will not work in the vehicle but I can hook up a 12 volt source from the outside and it will work what could be the problem?

I would think that either the fan switch or the resistor would be your problem if you've ruled out any fuse or wiring issues. By testing the voltage going in & out of both components, preferably with a digital multimeter but a 12 volt test light can be used, you will eliminate purchasing parts needlessly. If you end up getting voltage to the fan then see below remarks.

The blower motor still could be bad depending upon how you're jumping it. The vehicle wiring is only equipped to send a certain amount of amps to the blower motor & you may be using wiring that is larger, or connecting directly to a power supply that would make even a weak motor work by providing much more amperage than the vehicle usually does..

You can generally note that a worn motor doesn't turn by hand as smoothly as it should, causing the need for maximum amperage to get it started, tough to do in a car when everything is cold.

I suggest a Vehicle specific manual to aid in troubleshooting if you are unfamiliar with removing those components.

good luck.

The fan does not blow. Both fuses are good [40 amp under hood & 20 amp under dash]. Heat does come through when driving but the motor does not blow. I have read to check the cable to the heater coil...

Normally, blower resistor for aircond car can be fuse blow. (Thermal fuse type). In my case, civic 1.7 ex 2002, i take out a part (DENSO 077800-0682) and open the black cover. inside there, have electronics board with some components. The Thermal fuse is paraller with Power FET. If you can't get the thermal fuse to change (checking using ohm meter to confirm it has cut off), just take a small wire and soldering between to leg of the thermal fuse. Then, try reassemble your blower resistor denso 077800 and try on your aircond.

Blower motor stopped working, where is the blower located and would replacing motor solve problem?

the brush's are probly stuck open / did you look on the fire wall for a blower fan shape it's probly hiding up inside on the firewall or under a fender /if you can find the motor try giving it a good sharp rap on the end to free the brush's and hope it gets a little more life out of itself otherwise you need a new fan blower motor .[I@40be55&currentPage=1&vehicleNValue=&navValue=15200099&parentId=52-0&fromString=&fromWhere=null&filterByKeyWord=&categoryNValue=&categoryDisplayName=Climate+Control&_requestid=433411
