- How to fix and test your heater blower motor system if it is not working. In this case, the car needed a resistor. I used a power probe, and a test light to diagnose this. This particular resistor is the same for most 2001-2010 Chrysler Town & Country, Plymouth Grand Voyager, Dodge Grand Caravan, with manual HVAC controller, and also 2005-2007 Chrysler Pacifica. 2002 2003 2004 2006 2007 2008 2009 01 02 03 04 05 06 07 08 09 10

Thank you sooo much for posting this video!! I had the exact problem and went for over a year without my front fan! After watching your video, I started troubleshooting the plug and wiring. It turns out my issue was only a bad, corroded connection on the black wire on the terminal block. THANK YOU!! GREAT VIDEO!!
Welcome.
Good diagnosis, and a nice Power Probe tutorial. Thank you for sharing.
One of those, I don't know what I'm doing until it's done videos. You're welcome.
Great video and I'm glad my motor is good- tested it with a small 12v battery jumped onto that 2 wire plug after taking it out, and the blower turned on, so it's my resister that needs replacement
Good video...exactly what my problem was. Thx
I have fix my trouble thanks so much
I was dying when all the trash fell out of the glove box!
I really enjoy your channel, I hope you keep getting subs! I've made sure to add your channel on mine, I hope others will see it.
Power Probe is a great tool! More people should know about it, it saved me a LOT of time when I needed to check all the tail light wiring. You might even want to do a full video on the Power Probe, show how it can power up different things. This video was a good use for it. Thanks for sharing. Hope you had a good Christmas. You get anything amazing from Santa? Any more kids fighting outside in the street!?
There are a gazillion video's on power probes out there. I see it as a standard technician tool that is so common, it's not worth mentioning. Most regular people will not buy one, and you're not a technician if you don't have one.
Yeah, I agree. But if you were to make one, you'd put a good spin on it. I don't use mine a lot, but when I do, it's a great time saver and I'm all about that! My buddy is a new car tech, he should probably get one. It would make a nice birthday gift!
Maybe if I use it in enough video's, I will just cram them all together, so it looks like it is good for something.
There ya go!
Way to go. You saved me some $$
From san diego ca. Thanks
Great Video, FYI, not a diode / resistor . . It IS a - FUSIBLE LINK . . . Thank You Again, for a GREAT video . . God Bless . . .
I think you are incorrect. A fusible link is a fuse in a wire.
Thermal fuse. They put it next to the resistor to make sure it doesn't get hot enough to catch something on fire. If resistor gets too hot it pops the fuse.
Since I have no power coming into or out of my resistor, what would that mean? All my fuses and relays are good. I even put in a new resistor. But I'm getting no power apparently, to my resistor. I used a test light to probe my new resistor and wiring. It would seem I'm getting no power to my resistor.
Check your controller switch.
resistor was nice and cheap? How much was it? Cheaper to just install a new diode in that assembly? Thinking diode is cheap and solder in. Thanks for your feedback! Thanks for the video!
You could fix it, but those things are little toasters. That's why there is always air blowing on it. I always buy a new toaster.
Hey guys anyone can help me out ?
I have a 01 dodge caravan and I recently replaced the resister but my wires keeping burning and the fan speed isn’t working at all , is it maybe the resister again or is it the heating fan ? My mechanic has already soldered news wires but more our burning now
Thanks for the video. If you don't mind what tool is that you are using to check the fan with?
Power probe?
@@RustBeltAuto Yes the power probe, my apologies for not specifying!
2001 thru 2007 Caravan and Town and Country only. Vehicle platform changed in 2008 and, by the way, much easier to replace than this model.
Thanks! Do you know if the newer ones are pulse width modulated like the newer GM's, or is it still an old fashioned resistor?
That was nice of you to toss the candy you didnt have to do that but you did
Yup.should have just picked it up off the dirty dog hair covered floor and put it back in there 4 the kids. What a a hole huh.
My 2003 Caravan just clicks when I try any level. No blowing.
Hi,
I bought my Caravan and it came with wind speed 4 not working.
I replaced the blower motor resistor and it worked for less than 1 month, and speed 4 stopped working again, I thought the part I changed could be defective. Then I bought a new blower motor resistor and again in less than 3 weeks speed 4 stopped working.
The other speeds work normally.
Any suggestions as to what could be causing speed 4 to stop working?
Thanks
High speed doesn't use the resistor. It is a 12v supply. Is your harness, or connector burnt, or looking like it got hot? Wiggle test connector? I don't know.
@@RustBeltAuto I'll check what you mentioned.
But the interesting thing is that speed 4 worked as soon as I changed the blower resistor motor, but only for a few weeks, then it stopped working again.
Thanks
@@zanzangado you moved the connector around.
@@RustBeltAuto Well thought.
I'll check that out, thank you very much.
I wish you help me with my 2010 Town and Country. Bought new blower fan and control module. No power at all. Rear ac system completely functional.
@@americanpatriot2999 check your fuse. Make sure the connector is not burnt.
In my 05 we removed the resistor under glove box and now the rear is out too. Or does it control both.?
You mean the resistor? There is one for each.
@@RustBeltAuto edited that. Yes resistor. Your saying the one resistor controls both front and back. That would make sense then. I'm just going to replace it new.
@@2Jeezuzisreal no. There is one for each.
If it's whining and grinding and keeps stopping then it's the motor bearing? Resister when no movement after testing directly the motor moves? Just makingsure I understand correctly.
Your motor should be quiet.
@RustBeltAuto ok I am replacing motor. And will need to clean the drain as the cage was full of water. Update replaced motor cleared drain nice and quiet and heat distribution is fine for every setting. Other than ac compressor isn't kicking in. So that's next.
It’s kinda goofy love the accent.
Dude U R way tooo funny !!! LOLOLOLOL
My heater and air were making noise before they stop blowing air
If ah the black and green wire plug is toast what would that imply
Resistance makes heat.
So the plug resisted the power, thus beingoverthown by the resistor?
Ill have to rewatch the video p
@@yorkfirepulse8724 it depends. 1. It's a resistor. Resistors make heat. Heat melts things. The blower motor blows air onto it to cool it down. It doesn't always work as good as it should. 2. High amperage, and loose connections make resistance, connections in general make resistance, creating heat. 3. Technically a failing blower motor can create over amperage, creating resistance in wires, and resistors that cannot support it. Just replace the connector, and resistor. If you want to test the current after, see if it gets hot after running it for a period of time, and check your ground have at it.
Thanks bro i didnt think ud respond and well
I got a new resistor it looked like the prevoius owner did the same
So with that i will direct focus to those
Ah thanks a million, sincerlery
Human- person
There will tell ya how well it turns out later homie
Clarifacation noted tumbs up
Ok but what's the part number for the resistor?
Ask the parts store.
@@RustBeltAuto thnx....had a bad blower
yeah, thanks for helping us 'electrical losers' on this. i'm going w/ jumper cables and little wires to test the fan...
I don't think that's a diode. I pulled mine out and the numbers on it track to a thermal fuse. Mine showed an open circuit both ways. I found one on Amazon smile.amazon.com/gp/product/B0115D709O/ref=ox_sc_mini_detail?ie=UTF8&psc=1&smid=A2QJE0ZA90KWTL. $6 for 5 fuses not much savings compared to an all new resistor block, but satisfying if you're a fixit junky. Thanks for the good info on where to look and what to look for.
I never knew. Thought it was a diode. Thanks!
I wish I could find a mechanic that knows the difference btwn a resistor/module so I can get my ac/heat fixed🤔
What? Basically, a resistor reduces voltage, and a module reduces amperage. A motor that requires a module, basically soaks up as much power, as you can give it, until a fuse blows, unless it runs on a duty cycle to lower the current flow going into it. Correct me if I'm wrong. Is this a trick question?
@@RustBeltAuto it's not a truck question. My air/heat went out @ the same time & my mechanic says it's a part that goes in the front dashboard. He said I needed to replace (08 Dodge Grand Caravan) the resister.
I meant to say truck, not trick.
@@bigmama72. that should have a resistor, and not a module. A module is a solid state device. They use one of those for blower motors on like newer chevy trucks.
@@RustBeltAuto Ok. Tyvm. Here in GA, the part I need can only be purchased at a Dodge dealership.
MONEY, MONEY!
Where?
@@RustBeltAuto in the glovebox 😂
