you will find it in the heater box, also where the blower is. it is easy to remove.
Blower motor NG. Blower motor resister NG. Blower motor fuse NG. Blower motor switch NG.
If you have no blower speeds check the fuses, check the switch and finally check the blower motor.
fuse? switch? Selector?
Blown fuse? Bad blower motor? Bad resistor pack at blower motor? Bad switch?
All you have to do is remove the trim piece from around the assembly. This will allow you access to the screws holding the switch in. Remove the screws, unplug the switch and take it out. Put the new one in.
check the blower fuse, temperature sensor on the radiator,switch on the dashboard and the blower relay switch.
it is probley not the blower switch. if your fan runs on 3,4 and 5 it is your blower motor resister.
The resistor in the heating/air conditioning system controls the blower speed. As the fan speed switch is turned, the resistor adjusts the amount of current to the blower motor, changing the fan speed.
If the Heater/AC blower motor has stopped operating on one of the setting, then the problem is not in the switch but in the blower motor resitor. This item has several coiled wires and is housed behind the blower motor just in from of the firewall. If the motor stopped working all together it could be a bad switch on the head unit. 1. Remove the coolant recovery/winshield washer resivoir. 2. Disconnect the electrical connector at the blower motor and the vent hose. Disconnect the cruise control servo (if equipped) and set it aside. 3. Remove the 4 screws holding the blower motor and remove the motor. 4: The resitor is exposed. Remove the bolts holding the resitor. 4. To install the new one, just follow the steps 4-1 backwards. 1991 through 1994 access the switch through the ash tray. Remove and replace 1995 through 2007 access the switch through the radio. Remove the radio by using to removal clips, or unbolt the bezel from the two bolts then slide then entire bezel out. Replace the switch.
If there is current going through the wire to the blower switch, try bypassing the switch with a jumper wire. If the blower motor works, then replace the switch. If the blower motor does not come on, then you probably need to replace the blower motor.
The heater blower switch and the electrical plug attached to it may be at fault. Remove the heater control unit from the dash and inspect the plastic electrical plug attached to the blower switch, you may see it has melted. The switch and plug is available from your local auto parts store.
have you checked fuses and relays? Yes, I actually replaced the blower motor module & that didn't work. The Blower Motor itself spins freely & there doesn't seem to be any electrical issues. Could it be the Blower Motor speed switch??? If so, is that hard to access?
the blower switch itself is located in the instrument panel. it adjust the speed of the blower. the blower resistor, if that is what you are looking for,is located beside the blower motor under the pass. side of the dash
if it's a e-250 take the battery out and remove the three screws holding the blower,remove the wire harness,remove drain discharge tube,lift blower out of cavity and re-install with new blower motor.re-connect wiring harness and drain,tighten screws making sure the blower is installed in the correct position.install battery with tie-down holder for battery tray. check blower,by turning the blower switch to low then medium,and hi.listenn for noise or cage hitting frame. If ok..your done.
There is a Blower Motor Resistor Pack. Either the blower motor speed control switch itself is defective or the Resistor Pack is bad.
Could be a blown fuse. Make sure the blower motor is not burnt out. Could be a bad relay switch. Make sure your dash controls are working properly.
The blower is controlled by the blower switch, blower resistor, and relevant power relay.
Defective blower motor, blower motor resistor pack, or blower motor speed control switch.
Check to see if you are getting power and ground to the blower motor - if so blower motor is bad. If no power possibly fan switch or selector switch Also check the blower motor resistor, found in heater plenum.
You can access your 2000 BMW 323 replacement blower motor relay switch from the inside of the passenger cabin. You will need to remove the passenger side kick plate to access the relay switch.
pull the top cowl up right behind the windshield. its just clips so just pry and be gentle. then remove the 2 screws that hold the top of the center dash, then on that is behind the ash tray. then pull dash out. next remove screws from hvac panel. then unplug wiring harness from blower motor switch. then un screw switch.
I have the same problem. what I do is tap on the heater blower (located below the glove compartment in the corner)which will magically make the fan work or remove the two gold Philip screws that hold the cover and spin the fan manually.
either the blower control switch or the blower motoer needs replacing
