    Thanks for the answer. How difficult is it to change the blower motor?

  • mechanic144 May 11, 2010

    it sounds like a blower motor issue...when you turn the switch on high and leave it there for an extended period of time, it sends straight current to the blower motor..therefore, the demand of current from the blower motor is greater and the resistor cannot keep up with the output for demand causing it to burn up..try to replace the blower motor and resistor as a pair first....that's always the best practice...

The blower motor is drawing to many amps,even if it sounds,and runs fine,this is the main cause for resister failier.

Usually its not that hard...just look under the passenger side of the dash where they would put their feet..and you should see a cover..almost like a plastic cowl..remove the cover and then you should see the blower motor...now please do keep in mind that all the mounting bolts may or not be visible at this point...if they are, remove bolts and drop motor out of housing disconnect elecrical connector, and give motor a twist..should fall out.. reverse to install..if all bolts are not visible then the one bolt in the back will be a real pain in the *** to see get at..that may require some creativity to get it out...and upon reassembly, just don't install that bolt...lol

you can get a new resistor and you have to start the blower at hi always to avoid over heating in the resistors and protect the thermal fuse, the second after you had started the blower you can select any speed.

2003 durango blower resitor keeps failing. I added a new pigtail and reister but failes after 3 weeks.


There may be too much draw coming from the blower motor itself. I'd had the same issue when my blower started going bad. The resistor replacement would work for a day or so, but then it would go bad. The motor is a relatively easy thing to replace ($50 @ buy.com) and only requires the removal of 3 screws and the disconnection of a wiring harness.

lmk if it this helped. If so, please vote!

2000 Oldsmobile Intrigue: Heat and A/C blower only works on "high".


This is a common problem when the heater resistor goes bad. It is located near or mounted on the blower motor. Replacing the resistor module will fix the problem. FYI, Sometimes the blower motor is still working but the bearings are going bad. This tends to cause premature failure of the motor resistors. (So if the resistors fail again I would suggest replacing the blower motor as well.)

Heater fan just quit working. Cant find a fuse for it anywhere. Checked the relay and the switch and they seem fine.


Blower Motor not working for all speeds or not at all.

What does it take to get air to come out the vents?

1. Power from the battery or alternator, wiring thru a fuse and possibly an accessory relay to the switch

2. Switch and wiring to channel voltage to the appropriate resistor corresponding to the desired speed

3. Resistor set to reduce voltage to the blower for settings less than high

4. Final wiring to blower and blower itself

Because there is usually no relay between the switch and the resistor, all of the blower current runs through the switch. This sometimes causes the switch to overheat and fail over time. Depending on how the switch is designed, the failure may allow multiple currents to run to the resistor pack, and this may in turn cause the resistor pack to overheat and fail. An example of the circuit I'm describing is shown below:


88d29df.gif

Note that if the above switch was to contact both terminals 2 and 3 simultaneously, there would be more current than the resistor pack is designed for. This can burn the resistors and/or blow the thermal breaker. Also note that if the resistor pack fails, the blower can still run at full speed.

Troubleshooting: The last sentence above is a clue.

If your blower is working only on high speed, the likely cause is a failed resistor pack. However, because of the other discussion above, you should also troubleshoot the switch to see if it is the reason the resistor pack failed.

If the blower does not work at all, odds are that the problem is the fuse, relay, or the motor itself.

Repair: The resistor pack is installed in the air stream of the system to help cool the resistors. It is usually accessible from under the dash on the passenger's side or sometimes from the engine compartment along the firewall. It is identifiable by the connector with several wires coming out-some going to the switch and some to the blower motor. The resistor is replaced by unscrewing it from the duct and reinstalling the new resistor pack.

The blower is usually accessible from above the passenger

Front blower only works on high, what part do i


There are two things I can think of that may be causing your problem. First the blower switch in the dash may be bad if you do not have an electronically controlled blower, if you do it could be the control unit itself, but usually they stop working alltogether. The other part which may be bad is the resistor pack on your blower motor.

If your blower has four speeds on it like most blowers these days then this resistor pack will have four resitors mounted on it. They look like coiled wires. These resistors vary the voltage coming from the blower switch so you have different blower speeds. Kinda acts like a filter dropping the voltage for the lowest blower speeds incrementally.

If you want to diagnose this yourself it shouldn't be too hard. You will need a 12 volt test light or a multimeter to test for voltage. The blower motor should be located unther the hood of your vehicle on the passenger side against the firewall. It looks like a round black box with wires going to it. Where the wires connect to it the resistor pack is on the other end of the connector inside the motor housing. There are usually two screws or bolts holding it into the housing. If you take these bolts out it should come right out. You can visually inspect it and you may notice some charring on the circuit board where the resistors are.

I would measure power with you test light from the connector before it goes into the resistor pack. If you are receiving power at all blower settings then your blower switch is likely good since this feeds the signal to the blower motor.

You can then use a multimeter to ohm out the resitors on the resistor pack. If any of them show to be open you have a bad resitor coil there. You have two options at this point, you can unsolder the old resitors that are bad and try and replace them with comparable resitors from radio shack. Or you can go to rockauto.com and order a new resitor pack. They run about $16.00-$20.00.

Blower motor vent selection switch not working


the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

The blower motor resistor is located on the back of the blower motor housing under the dash on the passenger side. It can be difficult to get at, but it is doable. Be ready with the ibuprofen the next day for your sore back. Remove the cover panel from beneath the dash on the passenger side. Unplug the power 'ribbon' wires leading to the resitor. Unplug the wires that lead from the resitor to the blower motor housing. There are usually two, one black and one purple that share the same plug. Remove the short hose that leads from the blower motor housing to the ventilation system ducts. Remove the blower motor by removing the three hex screws that hold it in place. Remove the resistor by removing the three hex screws that hold it in place. The resistor is right against the firewall so two of the screws are very difficult to reach. A slender flexible socket extension will make the job easier. Attach the new resistor in place using the same hex screws. Only 1 or 2 of the original three are needed (the part is very light) if you do not feel like fighting with the ones next to the firewall. Reatach the blower motor and reconnect the hose. Plug the power cable wires back into the resitor and the wire from the resistor back into the blower motor.
