DIY: Ford Ranger Blower Motor Resistor Replacement
Vložit
- čas přidán 6. 09. 2024
- Video tutorial on how to replace the blower motor resistor on a Ford Ranger. This is a fairly common issue amongst Rangers, Explorers, and most likely the Mazda B series trucks as well. The main symptom of a failing blower motor resistor is that your fan speed will only work on the high setting. If your fan doesn’t work at all, then there is most likely a blown fuse, issue with the blower motor, hvac panel problem, or a fault in the wiring. This particular vehicle I am working with here today is a 1998 Ford Ranger, so there maybe some variations between the years and models.

Tools/Supplies Needed:
-8mm 3/8” drive socket
-3” 3/8” drive extension
-3/8” drive ratchet
-blower motor resistor
-dielectric grease
-interlocking pliers
Procedure:
-start by opening the hood of your vehicle and then locate the blower motor resistor which is on the passenger side, along the firewall where the blower motor is located
-down towards the bottom by the inner fender arch you will see a large electrical connector which is connected to the blower motor resistor
-using an 8mm socket, 3” extension and a 3/8” ratchet, remove the two bolts holding in the unit
-this can be a fairly tight spot and you don’t necessarily have to remove the electrical connector first
-unfortunately I am unable to remove the electrical connect, I’m assuming the contacts are corroded which is a common issue amongst these trucks
-you can also disconnect the two upper electrical connectors to gain a little more room
-using the assistance of a couple interlocking pliers and a few minutes of wiggling the connector I managed to get it loose
-if yours are mildly corroded, you can allow the connector to soak for a couple hours in vinegar, then clean up using electrical contact cleaner
-if the connector is too far gone, purchase a replacement hardness and solder it into place
-reinstall the new resistor and apply some dielectric grease to the connector to help prevent corrosion
-connect the remaining connectors if removed and then test

Very helpful thankyou. Good lord those holes are a butt to find again when reinstalling. I find disconnecting the hose right above it helps a bit. Lots of patients and small hands. Fixed the issue❤️
Thank you for the kind words and happy to hear I was able to help!
TO ANYBODY STUCK IN THE COLD AND THAT JUST NEEDS A TEMPORARY FIX. GET A SCREWDRIVER, PUT THE END OF IT ON THE CONNECTOR, AND TAP IT WITH A HAMMER. THATLL KNOCK THE CORROSION LOOSE AND START IT UP. IF ITS THE BLOWER MOTTOR WACK IT A COUPLE TIMES JUST LIKE ON A STARTER IT CAN GET STUCK. KEEP TAPPING IT WITH THE HEAT ON IN THE CAR. YOULL HEAR IT KICK ON.
THANKYOU VERY MUCH! VERY USEFUL INFORMATION
Thanks, replaced the resistor & harness assembly, now I have all four fan speeds back. And whoever designed the placement of this thing is having a good laugh!
Thank You for this video, straight forward and very helpful....will be doing this today!
Awesome to hear and glad to help out :)
Thank you. The technology hasn't changed since before my '60 Ford Galaxy :) only the location.
No problem, happy to help!
My blower motor resistor packed up. 1998 model Ford Courier pickup truck. Parts are hard to comeby where I live and only option was to order online and wait for weeks for a part to get delivered. So what I did was connect the broken resistor coils with solder. measure the resistance with a multimeter. Got a new heating element that comes for electric stoves...costed like $3. Cut pieces to match the resistance on my original coil... soldered the new coil off the stove into the resistor coil pack. Whole thing took 10mins tops. Works like a charm and the stove heating element seem to be way better quality than resistor pack coils as it's meant for high heat operations.... So if you have the old style coil resistors, can't source parts in a jiffy.... this is an option
Woah. Good thing i saw this one. I was about to buy the whole blower 💸💸💸
Great Video. I bought a ranger with 176K miles on it and found the AC did not work. Fixed that(bad condenser) went to use the AC and it only blows cold on high. So happy to have air but thinking I will want to turn it down aftera while. Glad to find out it should be an easy fix.
Thank you for the feedback :)
Thank you. Veido was a tremendous help.
Thank you!
Thank you for helping people
Thanks for this video. Seems fairly easy to do.
Glad to help out :)
Thank you for this video! Was a bitch to put back in because I didn’t remove anything but it works great now
No problem, happy to help!
And Wow. I'm used to the nichrome coils opening up Not the plug rotting out like it did.
I worked on a Dodge where it melted the plug, had to get a new replaced from the dealer and splice it in.
Perfect great tutorial , thanks
You're welcome!
Yep, my problem on my 2000 Mazda B-3000
2003 ranger XLT 3.0L...fan working but blowing the fuses quick...fan motor or the resistor thing you mention in the video.?
Very informative! Thanks
Glad to help out and thank you!
Very good that's my issue thanks Guy
Thank you!
these are meant to be removed through the fenderwell, not under the hood.
take out the feder liner and it's right in your face.
Depending on the model. On my 99 2.5 with no options it’s right there, only thing in your way is the windshield wiper fluid bottle which will be in the way no matter where you go in from
Is it normal for the Air Conditioning to be on even when you only want outside air ? When the thermostat is set to cold, will it always turn the air conditioning on ? I can`t seem to get outside air ventilation without the air conditioning to engage.
I’ve wondered why just the fan, ac off would feel surprisingly cooler than expected. And now the blower quit working during a short road trip (~800 miles). Ac compressor replaced maybe 10k miles ago. 🤷🏼♂️
Easiest how to about this issue. Thanks.
Glad I could help and thank you for the feedback!
@@4DIYers no problem 😁 now if you could do one on the blower being on high and no real air coming through the vents.
That would be great.
Unfortunately I no longer have access to the Ranger. But that can be a blend door issue, the motorized actuator is not working or a flapper is broken/jammed or there maybe debris in the vents.
Will a bad resistor cause low air volume? Even on high speed,max A/C it feels like it's on low or second speed, It will blow on all 4 settings. All the flaps look like they're sealing. Thanks
What if air keeps blowing when in the off position?
My resistor is impossible to remove. 30min in, broke both tabs and still cant get it off with pliers/flat head, wd40 🙃
Would you show me where is the blower relay and fuse in a Ford Ranger 02 2.3 L please my blower motor does not have power
Ty sir
Had the same problem on my VW Golf mk2
Fairly common issue amongst all vehicles and they'll all have the same symptoms. Designs will vary between these, some are more expensive than others unfortunately.
Is this the same for my 94 Mazda b3000?
I need a fuse diagram for a 2002 Ranger XLT, 3L engine
Would a bad resister blow the ignition fuse?
When I put it on max ac it blows cold but when I put it on ac it blows warm any idea it’s driving me crazy I would appreciate it if you can give me some idea thank you
Check your blend door, it's a common faulty area.
@@4DIYers yes that was the problem thank you for the response I love the video that you post awsome job thanks again i really appreciate it 👍👍👏👏👏
where's the music I would have some Boston playing in the background full volume
You should show it with the camera for us noobs. Good video tho!
My AC works good, but the blower slows down after some time, As soon as I toggle between different settings, it starts up again, and than in a few minutes it slows down again. So I'm flipping back and forth from regular AC to Max AC.
Any idea what the problem could be?
Could be looking at a corroded wires, a faulty hvac controller, or a failing blower motor.
Well I guess I'm barking up the wrong tree. My issue is not heat. I can see the blend door move so that tells me the vacuum is working properly. I have replaced everything dealing with coolant, thermostat, hoses, water outlet.
1:35 ...interlocking pliers?
Tongue and groove pliers.
what would cause the heat control to stop working?
Like the temp won’t change?
It was the door actuator for temperature control.
I did also replace the resistor so that my fan would change speed. This video was a great on that. Thank you
Mine runs very slow, like slow, slower, very slow and nothing.

Mine was doing the same thing, only working on high and sometimes you'd have to give the blower motor a couple taps for it to come on. Luckily it's a cheap part and a easy fix!
