SOURCE: blower motor

Strip fuse is blown should be by the driver side strut mount in a tootsie roll shape snap box. Or its the blower motor regulator which is under the blower motor.

I changed blower motor & resistor. I to replace motor and keeps blowing 2 15 amp fuses in box under hood.

well the blower is not shorted.
there can be a short anywhere from the switch to the blower.
did you look at the operators guide first to see if the fuse size is correct. man blower suck 13 amps. or more.
changed? does that mean a new blower or used?????

a blower can be hand tested and hot wired
i do that with 2 things.
a jumper clip with 20amp inline fuse and 16gage wire.
and my ammeter connected. (clamp)
if the blower works and does not suck too much current its ok.
its just a simple DC brush motor.
and can blow and still be bad, see why? ( armature segment shorts)
but sounds to me like harness shorts.
if the fuse blows with no resistor and no blower, its a harness short.
i dont have fuse box spec, so you will have to find that.

OMG, i looked in the online fsm.
what wierd car..... this blower.
its got 2 fuses for that blower,
EB5 and EB6 wired in parallel,, what joke that is.
the short must be on the blue-white wire (ONLY)
if at all.

here is the proof.
amazing how books work. huh?

The blower motor isn't working when cutting the climate control on..The compressor is working but no air is blowing out. is there a fuse that operates the blower motor?

Yea, check all your fuses first

blower motors work by way of electrical resistance. Imagine how a dimmer switch works in a house, thats all your doing when turning the fan speeds up or down, just adjusting the voltage to it, well there are generall 3 coils (dont quote me exactly here) but anyways these coils offer paths for electricity but also resistance...well just like when you rub your hands togethor fastly they get warm, these coils im talking about will actually glow they get so hot, and eventually they could just break from being hot to many time.. I know thats a long answer to what the problem is, but knowledge is power they say.

so if there is no air coming out then theres definetly a problem, either fuse or bad blower motor,

Blower not working

To determine the cause of a blower fan failure, isolate the motor, and perform some basic electrical tests.Check fuses first. Fuse failure often causes component failure. Check for power at the motor itself. Test the connection to the blower motor. Test the switch.-------------------------------------------------------------------

The blower for my heater isn't working. How do I fix it?

Yes, there is a fuse. NO, there is no way possible for the fuse to be the CAUSE of your blower not working. Yes, the fuse may be blown, but fuses do not just go around blowing themselves out to make your day miserable. If the fuse is blown, there is a reason for it. Fuses do not cause elecrical circuit failures....electrical circuit failures cause blown fuses.

Nobody can tell you what is causing your blower to not work without first DIAGNOSING your blower motor circuit. There are probably some people that would tell you to just replace the blower motor. However, I would not recommend that because "diagnosis by parts replacement" can be VERY COSTLY. You might get lucky and it will be the blower motor, then maybe not. If not, then you will be out the cost of the blower motor and still have no air.

If you check for power and ground at the blower motor electrical connector and all is well, then it is the blower motor. If you check for power and ground at the blower motor connector and either power or ground is missing, then you will have to trace the rest of the circuits to find out where the failure is.

My blower for my heat inside my 1992 honda accord stop working.I check the fuses they all good .What"s next for troube shooting.

If you park your car around leafy trees, it's possible your blower sucked in leaves and jammed it, which happened to mine. On the other hand, your blower motor could just be worn out. Either way, you'll have to remove it and check for blockage and check for continuity, meaning make sure the motor is still electrically functional. It is also possible that your fan switch went out, or a broken wire behind the switch. I would check the switch before tearing into the ducting to get to the fan.

1996 ford contour heater blower motor doesn't work. only worked on high before

First, check the blower motor fuse. If it is ok, disconnect the electrical lead from the blower motor, and apply direct power and ground to the motor electric terminals. If the blower motor fails to operate, it is defective. If the blower motor now operates with direct power, but doesn't when reconnected to the car's electrical system, there is likely a problem with the switch, the blower motor resistor, or a bad connection in the wiring. Hope this helps.

Heat fan stopped it a fuse?

It could be the Blower Motor Fuse or Relay and they should be located in the cabin Fuse Box, if both are OK, it could be the blower motor resistor, located on the blower motor housing, it is the part where the electrical connector goes into and it's got a pigtail connector that goes to the blower motor, it is attached to the blower housing by three screws. Here are some pictures for better identification.
FRONT VIEW 1kbron_5.jpg
SIDE VIEW 1kbron_7.jpg

To test it, make sure the electrical connector has voltage when the FAN is on, if voltage is present, it means relay and fuse are OK, plug the connector into the resistor and check voltage on the pigtail connector, if voltage is present, the resistor is OK, voltage varies according to the speed selected. To check the blower motor, apply 12 volts and ground the the motor terminals, it should kick in in Hi speed, if not Replace Blower Motor.
A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.
