Front blower motor quit working replaced ignition switch,control module,resister,and blower motor but still doesnt work fuses are all good where do i look next


normally it is the resistor,( relay) then resistor module then motor.
did you test the relay(I believe located under hood, relay/fuse center), If OK check plugs and wires for melting, damage and good connection, grounds should also be checked. Use a volt ohm meter to see if you are getting any power ti motor,etc.

I have a 2002 GMC Savana Cargo van with a a/c and heater blower that will not work. The problem started when I lost the low speed, then the medium, and finally the highspeed. Fuses and relays are ok.


You checked the fuse and relay, did you check to see if you had power at the resistor ?
American built vehicles control fan speed by the power circuit which goes thru the resistor. The high speed usually bypasses the resistor.
You may need a new blower motor or control switch.

Blower motor resistor


Locate the blower motor and look around the outside and close to the motor for a 2-by-3-inch plate held on by two or four small screws. There will be an electrical connector plugged into it with five or six wires, depending on the vehicle type and heating and air conditioning type of control panel.
Test the resistor before replacing it. It is always recommended to test any electronic unit before replacing because there are a multitude of things that could cause the same symptoms. It only takes a few minutes and can qualify the assumption that a part is bad. It will save money to replace or repair the right part the first time.
Check the speeds by turning the fan conrol to all positions. Take note which fan speeds work and which speeds do not work. If the fan works only on one speed the blower motor resistor is very likely bad.

Check the fuses if the fan speeds do not work. The fuses for the interior heating and air conditioning fan are usually under the hood in the fuse and relay center. If the fuse looks good, then take it out and turn the ignition key on and use the volt meter set at 20 volts DC. Check to make sure that there is voltage to the fuse. If not, check for an open circuit to the fuse.

Check the relay to determine if there is power at the fuse. The relay should have two of the four terminals showing power. With the key on and the fan turned on, remove the relay and put it back in, listening for it to click. If it does not click, then replace the relay.

Check the voltage at the electrical connector on the blower motor resistor to see if the fuse and relay are good. Make sure that power is present at the connector with the key on and the fan switch on. There should be power at two terminals of the blower motor resistor. If only one terminal has power, replace the resistor. If two terminals have power, replace the blower motor itself. Remove the screws and unplug the connector to remove the blower motor resistor. Put the new one in its place by screwing it back in and plugging in the wiring connector.

No power to the blower switch or blower motor or to the connector or resistor-relays and fuses are ok so are the items previously mentioned


I would 1st jumper 12 volts to the blower to see if runs, the motor could be defective, it is fairly common. If the blower checks ok then replace the blower motor speed control resistor (located next to the motor plugged into the air ducting for cooling of the resistor), the thermal limiter fuse that is part of the blower motor speed control resistor is blown.

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.

Heater blower stopped working??


Check fuses, there may be more than one fuse that controls the blower motor. If fuse is OK, then check relays (somewhere in a box). If relays and fuses are OK, then check (some dashboard dissassembly required) if voltage is getting to the blower motor. If there is voltage present, then suspect burnde blower motor, or if motor works only at full speed, then suspect a burned resistor in the blower motor assembly.

in the duct work where the blower motor attaches you will see the resister block. it is held into the duct work with two or three screws and there is a wiring going to it. undo the screws and pull it out carefully and replace it. your fan should work fine after that. be careful if the circuit is live as it does heat up alot.
