2003 chevy silverado blower motor wont work i tested blower motor it works i just replaced the resistor and still dosent work, i also checked the fuses and the are ok please what else could it be


Is the blower motor not getting power or ground ?
There are two fuses that power the HVAC control module. The module controls the blower motor processor and the blend doors.
Have you tested the module and processor ?
You may need a shop manual for the wiring diagrams and procedures.

Blower wiring diagram in a 1994 jeep cherokee


Well, not exactly.
The blower switch gets power from the control panel that gets power from the 25amp fuse in the fuse box.
The wire from the fuse box to the control panel is black and tan, the wire from the control panel to the fan switch is yellow and brown.

I have replace the blower switch pigtail rerister still no blower working could it be the relay if it is where is it ? the blower motor and relay are the only two things left to change need help thanks


Do you have power to the blower motor?

With everything connected there should be power on both wires going to the blower motor. If there is no power than remove the blower motor relay in the fuse block under the hood. There should be power at two of the pins and two of the pins should be grounded. One pin is powered by the 50 amp Blower fuse and the other gets its power from the function selector (the switch that controls where the air comes out.

If only one pin has power than pull the 50amp blower fuse If power goes away than you know that the relay is not recieving power from the function selector. That is powered by a 15 amp fuse in the cetral fuse block (under the dash i think). If that fuse is good than check for power at the pink with black wire at the function switch. If there is power there tan check for power at the yellow with red wire and the function switch. If there is no power than you have a bad function switch.

This is a ground side controlled blower motor. The speed switch controls the path to ground. so if there is power to the blower motor on the orange with red wire you can ground the orange with black wire at the blower motor and it should run.

That should be enough info to get you started. Let me know what you find and I'll be happy to help further.

The heater / blower in my 1992 dlx has stopped working all fuses ok


Hello hfg.

1. First of all, tap the blower motor gently to see if it starts it. If it does, the brushes or the armature in the motor are worn- replace the motor.
2. If that doesn't help wiggle the connector on the motor and the blower motor resistor. There may be burned or loose connections.
3. If you have power on fuse 7 with the key on, then check for power at the blower motor on the blue white wire. If no power on it you have a break in the wire between the fuse and the blower.
4. Next, check for power on the blue black wire. If there is power there that proves there is continuity through the motor(that's good), if not, replace the motor.
5. The blue black wire then goes to the blower resistor. this resistor gives the different blower speeds.
inside the resistor there is a thermal fuse. It isn't replaceable, only the resistor as an assembly.
If the thermal fuse blows it may indicate that the blower motor is beginning to wear out and draw too many amps. And then you may need to replace both the blower and the resistor.
Check with an ohmmeter across the thermal fuse. If it is open circuit, replace the resistor and the blower. If you don't replace the blower it may blow the new resistor again.
6. If it all checks out to this point, ground the blue/red wire at the resistor. If the blower comes on the problem then becomes the blower switch or a break in the wire to the switch.

Whew.. Hope this helps solve the problem, my fingers are sore..Ha.

Thanks for using FixYa.

The blower motor for the heater/AC does not work after replacing it. All fuses are ok


OK, history would be nice. What a/c do you have, Manual or Auto/Electronic? All Speeds? Why did you replace the motor. If the fuses are ok, did you check for power at the motor? if it has power and ground, it HAS TO WORK, or the motor is bad. If you did not check for power, then if you have Manual A/C, Turn blower switch to HIGH SPEED, check the PURPLE wire (at the motor), if it does not have power, then check RED wire at the BLOWER RELAY. The RED wire should be HOT AT ALL TIMES. If the Red Wire is HOT but the Purple wire is not, then check the ORANGE wire at the blower relay, it should be hot (if the orange wire is not hot you may have a bad blower switch ). If the RED and Orange wires are hot, then the relay may be bad, You can by- pass the relay to see if all is ok but connecting the RED AND PURPLE WIRES. The blower should run at high speed. I dont want to look at the Electronic A/C, its more complicated and I dont want to waste time if thats not what you have.

1996 Dodge Dakota A/C ...plus blower motor problem


You may have 2 problems - the blower motor I believe should have power all the time and the speed is controlled by grounding the circuit through the various resistors. I think you need to get some wiring diagrams.

Blower control switch


do have any power on either wire going to the blower. the power runs from the fuse block through a relay, to the blower, to the resistor block and finally to the dash control. of you have power only on one side of the blower replace the blower. if you have no power at the blower replace the relay.

Hope this helps.
