Question about 1997 Nissan Pathfinder

1 Answer

The blower motor won't turn off.

Checked the position setting switch with a multi meter and found no problem (In off position had no continuity).

Pulled both fuses and blower shut down. Put one of the two fuses in and the blower turned back on. I assume the tw 15 Amp fuses are in parallel to accommodate the in rush when turned on full?

Please help. Winter is comming and gas is expensive.

Sounds to me like there is a direct short somewhere in the system. With no continuity through the switch, the blower should shut off. So this means that there is a connection somewhere else supplying voltage to the blower motor. How rusty is this vehicle? Suggest you start looking for a damaged, salt and dirt encrusted harness somewhere under the hood, low enough to collect dirt, salt, grease and moisture. My guess is that you will find a collection of blue/green corroded wires somewhere. This could be time consuming, but you may get lucky and find it quickly. Look for the obvious. A year/ model specific factory wiring diagram...available over the a good investment, and may save you much time. If you are keeping the car, get one. You'll be glad you did. This will also tell you if the system is supposed to run on 2 -15 amp fuses, or if that is also a malfunction. Trust me, chasing electrical ghosts is a real pain, especially when you don't know where they are hiding. Keep me posted. Good luck. Chip

    Chip here again.....
    This just occurred to me....does the blower motor run with the switch removed? If it does, then there is a short as I said before. If it does not, there is a better than fair chance that you misidentified the terminals on the switch when testing the switch. Have you tried finding the terminal supplying the voltage to the switch, and then using a jumper to connect it to the other terminals one at a time? Just something else to consider.....again, good luck.

The blower blows high speed all the time unless you turn unit off. It cannot be adjusted by up/down control. Any suggestions on what to check? Thanks...

Start by removing your glove box. Behind it you will likely find your blower motor. Access the harness plug to the blower and attach a multi-meter. turn the ignition to 'ON'. turn the switch through it various positions while monitoring voltage output on the multi-meter. If you see voltage through all postions replace the blower, if not than its the switch. dont forget about checking wiring and fuses before you begin. If you want one on one help or more detailed advice I'd be happy to walk you through the process you can contact me through my website : Home

Front blower motor not working

Grab your multi-meter and first off check the blower fuse visually if it checks out then you won't have to fetch meter for next step:-) With your meter find the connectors TO blower - turn key to on position, no need to start then with meter switched to DC POWER see if you get a reading indicating power to motor if you are getting power I pronounce the motor deceased--if not then the next step will be tracing the wiring to find a break or bare spot that could be grounding it out good luck

Wont start

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage.


NEXT Test the PUSH start switch with meter for OHMS. Should show OHMS when pushed in or on start, and no ohms or infinity when in off position.

If you hear a humming/clicking sound from motor area you more than likely have a bad motor.
Try this test out to see if u have weak windings or relay/capacitor on motor.
Open the dryer door and turn by hand the drum while machine is on ON position. And you or someone else presses the door engagement switch in. If it starts up then u have bad windings

Another thing to check is the belt safety switch. With a multi meter.
Especially if u just replaced the belt. The belt safety switch is attached to the Tensioner and motor. IT LOOKS LIKE A DOOR SWITCH SOMEWHAT a little black pc of plastic with 2 prongs going into it. Sits at bottom of motor. Under the Tensioner. Attach meter clips to the 2 prongs on switch, Then when the little white push button is pressed in it should show continuity and none when released.

Lastly check ut push start button for continuity with a meter when pushed in the on position, it may have gone bad.

2010 DODGE caravan a/c blower fan inop have replaced reistor and control head rear fan works have checked all relays and fuses

Hi Jim, I will try my best to help you. First off, let see what we are losing at the blower motor. Three things I want you to do. #1-With a multi-meter check the power side at the blower motor connector and see if you have a full 12 volts. #2-With a test light hooked to the battery positive terminal, check the ground side at the blower motor connector to see if you have a good ground, the test light should be good and bright. #3-With the multi-meter set on ohm's check across the actual blower motor connector a resistance reading of up too 7 ohms is OK, but if you have a reading above like 14 to 22 ohms then replace the motor. Hope this helps and have an awesome day Jim!

Blower motor won t work

A bit of troubleshooting is needed to figure out what is wrong. Most common possibilities are blown fuses, blower motor resistor failure, motor failure, or switch. Assuming you've already checked the fuses or you would not be posting for a solution... ;)

Without some electronic testing with a meter I'd think towards this checklist:

Sometimes when a cabin heater fan motor is failing you can give the ductwork around the fan motor area a fairly good wrap with your hand (not enough to do any damage to the duct work or your hand, if it hurts you hit it too hard!) while it is powered on and if the motor suddenly starts turning that usually indicates fan motor failure. Or if it seems to work in warmer temps but not in colder, that can also be a sign of a faulty motor.

With the vehicle off and battery disconnected the blower motor resistor and it's connector can usually be visually inspected for degradation. You can Google up your make/model/year of vehicle along with "blower motor resistor" and typically get a visual of where thething is located and what the part SHOULD lok lijke, Typically they are up on the firewall somewhere. YMMV

If those check out, and you have of course ruled out the fuses, I'd start thinking about the switch, but before I took the time to tear into the dash I'd get a halfway decent digital multi-tester for ~$20-$25, and learn how to use it to test the switch, motor, and wiring. Otherwise it's just a lot of labor and guess work, and those motors and switches can both get pretty pricey.

Good luck!

Blower working on top 2 settings but no air comeing from vents


Thanks for using FixYa. The possible causes due to which the blower is not working normally are fuse, blower resistor or a bad blower motor. Test the voltage at the blower with a test light. Please check the motor relay switch fuse under the dashboard. Use a multi meter to measure ohms for continuity. If these are fine, bypass the blower motor relay switch to make sure blower motor is running fine. Motor relay switch is right next to radiator fan relay switch under the hood. Pull out the blower motor relay switch to see 4 female pin holes. Test the relay switch using a 12 volts power source and a multi meter to measure continuity. If fan works after jumping the pin holes, then blower motor is fine but relay switch may be faulty. You may also need to replace the blower motor resistor. If still the problem persists, then you need to replace the blower motor.

Please do rate the solution and revert for further assistance.
