If its anything like a 95 model, that unused plug near the blower motor is used when setting the timing on the vehicle. It removes the ignition advance from the distributor. I would be careful about experimenting like that.
To troubleshoot your blower motor, go buy a cheap test light and unplug your motor plug. Connect the test light. Turn on your motor switch. If it lights when connected properly, the motor is bad. If not you have other issues. Could be a relay or resistor module. Just takes a little more troubleshooting.

Remove heater control switch


Before removing the heater switch on this 2006 citroen hdi I would first have the blower motor checked and the most common reason for this and other blower problems would be the blower resistor.

Your blower works on and off at times, first locate the blower motor and the resistor. the blower motor is located on the heater box, look under the pass/side of the dash, you may have to remove under dash cover to see blower.
When you have located the blower now look to the side on the heater box, there you will see a connector plug, it plugs into a connection on the heater box, this will be the resistor, the resistor slides into heater box and the end of it bolts to box to hold it in place and then the connector plugs into it, if you can not locate it then follow wires that plug into blower , follow wires back they will lead you to resistor,
next time blower does not work wiggle connector to resistor and see if blower turns on, if it does then resistor is the problem. also unplug resistor plug at resistor and check for any burning of connectors at plug and inside resistor.

I would bet its a bad resistor or the plug is brunt due to high draw from bad connections, if plug has burn damage to connectors then replace the plug along with resistor.

Heater fan runs on high speed only


The lower speeds are controlled by the blower motor resistor.It is under the dash, on or near the blower motor assembly, held in place by 2 screws. 4 wires colors are: black with white stripe, tan, light blue & orange. looking at a new one will help to identify the bad one. sometimes the wire harness also needs to be replacing. That may be a dealer item. Good luck dr. volt.

Blower selector only works on #5??


The usual problem on these is the blower motor resistor.It is located by the blower motor on the passengers side under the dash.Just listen for the blower motor.You may have to remove a lower dash panel to see under the blower motor.Then just follow the 2 wire connector from the blower motor to the resistor.There are 2 screws that hold it in place.Just remove these and pull it down.You should see a burn mark on the resistor if it is bad.Also look the connector over real good.If the connector looks like it got hot and melted you will need to replace it also.You can get the connector with wires at the dealership.Hope this helps.Good luck.

The blower on my heater does not always work sometimes it comes on sometimes it does not. If it does not and i go over a bump it will come on. Someone told me it might be the resistor of so where is the...


The blower motor will be on the passenger side up under the dash,held in place with(usually) three machine screws .The resistor block will be close to this location, a series of 5 or 6 wires in a row with a screw at each end. The block itself is about the size of a credit card a you will be able to hold the block up to the light and give it a visual inspection.If you have a meter or can borrow one check each run with the continuity option.I must say that this is a good place to start but I would also be looking for a poor connection as I am working away. wiggle the wiring harness and see if you can get the fan to cut in and out.Good luck and watch your back,its tight under there.

How to change blower motor 2001 Kia Sephia


just offering advice on a general application for a broad number of vehicles as im not sure where your blower motor is.
car manufacturers know that the blower motor gets used as much as the radio, so they generally make it easy to remove and reinstall.
if you have the new blower motor , look under the hood for a part that looks like that one sometimes they put it under the passenger side dash
. also look at that new part and count the holes on the flat part and its usually 3 or 4 retaining screws that go thru the holes
find out where yours is on your car, and look for the screws that are holding it into place. those need to be unscrewed
its normally pretty simple to remove the retaining screws and unplugging the wire connector, then pull the motor and fan blade assembly out of the hole . now you most likely have to remove the fan blades and put them on your new motor. sometimes its a clip holding the fan blades on, sometimes its just a nut that has to be taken loose.
put the fan blades on your new motor , put the motor back in place and put the screws back in place and plug it back in.

First thing i would do is unplug the old fan connector, and if you can get the new fan close enough to the connector, plug the new motor in the connector and see if it spins ( before you try to take the old one out)
if it spins , then the problem is defianately a bad motor and you need to switch it out

Where is blower motor resister on 99 chevy pick-up


There is a cover that you have to remove under the blower motor on the passenger side. It goes halfway across the bottom of the dash it is held in place with 4 screws. I think they are 7 millimetter or 5.5 millimetter. Once cover is out of the way look by the blower motor and you willl see the resistor the wires plug directly to the blower motor those screws are 5.5. I hope Ive been a help. Thank You

I need help replacing my blower resistor. I don't know where it is located....


Look down under the dash on the passenger side. You will see the blower motor. The resistor switch is just a little lower and to the left. It will have a plug going to it. It is not real hard to replace.

Hope this helps.

2003 Buick Century Low Speed Blower


You may have a bad blower motor resistor. The blower motor is located in the passenger side foot well. You will need to remove the kick panel on the passenger side to get at the motor. 
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. Remove the cover panel from beneath the dash on the passenger side. Unplug the power 'ribbon' wires leading to the resistor. Unplug the wires that lead from the resistor 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 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.Reattach the blower motor and reconnect the hose. Plug the power cable wires back into the resistor and the wire from the resistor back into the blower motor.


Good luck and hope this helps.

Blower on the heater/AC not working on 1998 Escort, checked fuse under dash?


Ok, first off, check the fuses under the dash. If they're all good, does the blower work only on high speed? If yes, then you have a bad blower motor resistor, which is located under the hood, near the blower motor itself. If the motor doesnt work at all at any fan speed, make sure the wiring harness that plugs into the motor under the hood is clean and tightly installed. If it still doesnt operate, sometimes tapping on the blower motor housing will kick it on, but if that doesnt work, you may have to replace the blower motor. They are available aftermarket, and arent usually too expensive.

Busted blower motor


May be your resistor . Usually Up under dash (passenger side) near or at blower motor. Wire plug will go into it, and out to blower motor if external.
