Blower motor not working

My blower motor on our 1999 mercury cougar will not work on any speed. Could this be the resistor or am I looking at the wrong part for replacement?

    99 cougar blower motor problem (not blowing at any speed) have ran a jumper from battery to the blower and it spins. Have tried a different resistor but still doesn't operate. What might the problem still be? All fuses are ok. Our stereo has quit working as well. Could both of these problems come from a bad accessory relay or ignition switch problem? Thanks

If you do a voltage check right at the motor you'll know for sure. I usually use my test light or multimeter and poke into wires at motor. If no voltage, start back-tracking which usually means resistor next. If you have 12 volts going to motor & it's not spinning, then I'd be pulling motor. You can manufacture a set of jumper wires to motor connector, and use a 12 volt cordless battery to test motor if you know how.

    Be sure to check all those fuses & make sure you check for power distribution box under hood probably near battery, just in case it's there.

When it will not blow at any speed it is usually the motor or the fuse.  If it is the fuse you may have another problem.  A bad resistor will give you full power but nothing else.

    If the fuses are good and the motor is good you might have a bad connection.  A multi-meter is a wonderful tool. Even a cheap one is useful. You need to slowly and carefully follow the electricity. You may have bought yourself a new bad resistor ( it happens). With the additional problem of the stereo. It makes me think again to a bad connection somewhere between the battery and the dead things. With a multi-meter you could check If the electricity is getteng to the fuse box, to the relays, out of the relays and so on. It is a long process of elimination.

My a/c went out on my 99 mercury cougar but that was because my a/c compressor went out. My heat was working after that and then it went out too. I thought it was my blower motor so i bought a new one....

You have two other components that control the blower, the control switch and the blower resistor block. The switch is the knob you turn to select the speed and will cause you loose power to the next component that is the resistor block. This part is usually next to the blower motor because it needs to be cooled by the fan and it is responsible for the different fan speeds. Either component can cause a total loss of the blower fan. Go to a online parts lookup like and it will show you a picture of the parts so you can identify them.

2000 mercury cougar - blower motor resistor- location and disciption would be helpful. p.s. if i were to unplug the resistor would the blower still work on high.

If you ahve manual a/c, it is in the plenum case above passenger fett afgainst firewall. 2 bolts, 4 or 5 wire connector. rear bolt is hard to get to, pull carpet down. If it fails a second time, you must repalce blower motor as it is drawing too much current causing resister failure.

If you have electronic a/c, you don't have a resistor. A blower motor speed controller instead.

We have a 2002 villager, the fan only works on Hi setting, Checked the 20 Amp fuse in the panel to the left of the steering column, as well as the larger fuse in the engine compartment. Both are fine. Is...

The blower motor doesn't use a different fuse depending on the speed. The most common cause for your concern is bad blower motor resistors. The resistors lower the voltage to the blower motor so it doesn't turn at full speed when you have it set to fan speed 1. When the resistors blow out the only setting that works is full speed because it doesn't go through the resistor.

A/c and blower does not work i have 14 vots to the fan but still wont work

If it has power you need to confirm if it has a good ground. If it does it may be a defective motor. If not it may just need a blower resistor or have a wiring problem.

Mercury Cougar heater blower only works on high.

remove the trim panel below the glove box and you will see the blower motor,just to the left of it you will see a 4 wire connector plugged into the case. This is the blower motor resistor,this is what you need to replace.

I had this exact problem, it is probably your Blower Motor Resistor. It is located under/behind your glovebox, one screw holds it in. Not too expensive either. If that doesn't work it may be your blower motor. Good Luck!
