- Honda Accord Blower Motor, Blower Motor Power Transistor (Resistor) and Cabin Air Filter Replacement 2004 (2003-2007 Similar). In this video I show how to replace the blower motor, blower motor power transistor (also referred to as a blower motor resistor) and the cabin air filter on a seventh generation Accord. This is a good DIY project that can save some money by doing it yourself. The exact vehicle in this video is a 2004 Honda Accord EX 2.4L Sedan. 2003-2007 Accords should be similar. Enjoy!

Amazon (and HondaPartsNow) are both saying the transistor for an '07 sedan is 79330-SDR-A01 not SDA like in your link?
@@ronaldjensen2948 Honda appears to have updated the part number for 2005-2007 Accords, for certain trim models.
Thank you so much! I am a 66 yr old grandmother on a SS income working for my rent (who had some knowledge of "older cars", and used to fix my own cars), but because of modern technology it makes it harder and harder, and your video "hit the mark" - was able to to it and saved the labor fees of possibly over $400! This car was a gift to me from my church so I could continue doing my caretaking for my rent (2005 Honda Accord EX) - God bless you! And thank you again!
Glad it was helpful, thank you for the comment!
This was a $50 fix for me and I can’t thank you enough.
Awesome, glad it helped!
Good job. Straightforward and no unnecessary BS.
Thanks 👍!
Just because the blower motor isn't turning doesn't mean that it's bad!!! I had the same problem with my car. I decided to test my blower motor by hooking two wires from my car battery (one on the negative one on the positive) to the two posts on the blower motor. The blower motor still works!!! It's the RESISTER!! Saved me over $105.. Always check everything!!
This was just a replacement video (I have diagnostic videos on blower motors), but I always recommend testing before replacing. A simple test light and jumper wires (or a PowerProbe) can give direction pretty quickly. Thanks for the input.
Thankyou so much for this. $45 for the blower on Amazon, about 30min of crunching and twisting myself into tight spaces into poses my body wasn't happy about. But I'm sure this saved me a pretty penny.

Exactly what I needed. Even the recommendations from RockAuto. Thank you sir!
Thanks for the comment 👍!
Today I installed an aftermarket blower motor and resistor both purchased from Amazon into a 2013 Honda CR-V. Honda has discontinued these parts for my model year probably because their ten year parts commitment is done. I had to remove a corner piece of the duct to access the resistor. The job was pretty straightforward and everything is working well.
I own 2 Accords, 2006 400K miles and a 2007 270K miles and I replace cabin filters 3 times a year for each one of them. I live in the North East and we have different kinds of tree leaves that make their way to the filter. Since the airflow goes down, the cabin filter catches more debris comparing to engine air filter. I always have my vacuum cleaner ready in case the cabin filter is stuffed and the debris falls down in the blower.
👍
Great work Dave some testing on the transistor would be sweet informative video
👍
Thanks for the video. As for the tab I couldn't find my shorty screwdriver so I cut that tab off. It's covered anyway.
Thank you so much, excellent explanation 👍🏽
Great video, very informative
Dude you are a genius 😎😂❤
On my 05 coupe the blower motor was held in by Phillips head screws, not star bit. This is mine and does not necessarily represent everyone. But I spent 20 mins searching for my ratchet screwdriver that could swap out bits when I didn't need to. My fault for not looking first. Oh and if you're going to swap the air filter you can take the glove box out and remove your problems with clearance to get the resistor out. Hope this helps somebody. I'm glad my vents are working again.
Thank you for your help
Dean tnx muchas gracias campeón 💪
Nice video. You tested the transistor and it seems to be working fine. You should just leave it. It either works or it doesn't. It is not a wear item. When my blower motor was worn, it placed a heavy load on the speed control module. As a result, it heated it up and burned the thermal fuse. I just opened it up and replaced the thermal fuse inside. It also burned the fuse in the engine compartment. Transistor works differently than a resistor. The transistor turns off and on (PWM) to reduce the blower speed. It does not bleed it as heat. The heat is produced from the inefficiency of turning it off and on. A resistor resists the flow of electricity and radiates it as heat.
The transistor works hand in hand with the blower motor to control the speed, not only do the controls wires go into the transistor but so do the blower motor power wires. I have seen too many times where a bad transistor looks like it is functioning properly but has damaged the motor and if you only replace the motor it will go out again very quickly after replacing it. This is why I typically replace both at the same time. And it certainly does generate heat when it is doing its job, a lot of it, which is why that heat needs to go somewhere (bled off into the air stream). Heat is energy and if the energy (in the case battery voltage at the blower motor) isn't being used by the blower motor (when it is turning at a lower speed) then it needs to go somewhere.
Thanks for the video. So many places charge a ton for this. I know my Honda dealer wanted $681 but believe that includes parts. I even called Pep Boys and they wanted I think $400 for parts and nearly close to $600 with replacing it. I see parts so much cheaper on the site you suggested. They do not have the part for the back of the assembly but might sell it separately as I do not know. It is amazing how much money places want for this. I would still have it done though as though it looks simple I would still want some one else doing it. I do not have much patience so would probably break a few items along the way.
👍
Great video very detailed thanks
Thanks!
Thanks for you help my friend 🙏
Thanks for the write way to repair 🙂
I appreciate the comment, thank you!
I was watching another video of a guy replacing the Resistor only in a newer car but still and older vehicle maybe about 2006. It was funny in the video it showed so much space that he did not have to use the small screw driver. What I found out after dropping the panel that you need to is that the car has a side panel that he seems to have removed but did not state this in the video. I guess it has some screws and not sure what kind to remove this. I was so surprised and freaked out when I saw how mine was. I still have yet to replace mine but I did buy the parts. One they have a newer part for the Resistor that has the heart now and which has a 3 year warranty. That one says it is better then OEM but not how. At least the one you suggested states how. For my car it will go for weeks blowing nice cool air and then stop and some times will start again when I get the car at highway speeds it will start to blow cool air all over again. It has kept me from replacing the parts but now it is getting very hot out so know I will need to replace them soon.
👍
Great video as always!
I appreciate the comment, thanks!
Great info,thank u sir👍
I appreciate the comment, thanks!
Great Video. Replaced resistor and now blower works! Fast forward 2 weeks and now the blower stays on constantly, only shuts off with key. On/Off switch won't control, but does increase speed up with fan speed controller. Any ideas?
You are awesome ! Thank you sir❤️
Thank you for the comment!
Good video.
Great stuff!
Thanks!
Outstanding video! Quick question, I replace the resistor and the blower motor for my 07 Honda Accord. It worked for about 3 months but now it runs constantly on high. The only way to shut it off is to remove the ignition key. Do you think I might of gotten a bad resistor?
same issue. Did you find a fix?
Great video
Thanks!
@ big Dog50001 Automotive I have the same issue Wth the blower motor on my Honda Accord 2004 2.4l lx 4 door sedan I have to hit the bottom to make the the blower motor to start sometimes it’s stuck I wasn’t sure if it’s a blower motor that makes a squeaking sound like a bird chirp at first I thought it was a serpentine belt and tensioner so I changed that still the same sound and then I changed the a/c compressor pulley and clutch still the same sound until I found your video I think it might be a blower motor that’s making that sound so the sound only squeaks when the car is in drive in a still position and drive but when u put it in park the noise goes away I knw my car have to excessive vibration cause of my engine mounts also the car is 16 years old so I’m not sure because I did order the oem parts online from cheaphondaparts.com so I’m not sure what it is can you help if it’s the blower motor or radiator fan because I got both because of the cars age
Hard to say. Might need an assistant to help you out by manipulating the car (taking it out of park etc) while you listen for the noise and try to pinpoint it. Otherwise you just throw parts at it which can get expensive fast.
@@BigDog50001 thank you very much I’ll try that and take your advice
How do you test the transistor
Nice, nice. Video helper !!!
"Have fun with that screw" 😭😂
Hey Big Dog hot a problem with my 2005 honda accord lx radio works but none of the A/C controls work and the blower stays on cant turn it off i have to unplug the wire from the resistor what can it be ???
Transistor also prolongs the life of the blower motor because the blower motor is no longer doing that work and bleeding the heat off
My blower works but the AC isn't that cold unless the setting is at max. Would this my blower or resistor?
how do you take off that white fan part to clean with soap and water. i removerd the squeez washer but still wont come off
Glad to hear you recommend TYC as I've had good experience with their headlight assemblies (on Hondas) plus they're half the price as OEM. Just curious, it appears that Honda superseded the blower motor/fan in 2013 but not sure what changed other than the wiring connector. Honda says the original p/n was 79311-tr6-a71 but superseded by 80030-TR0-305. Many sites say to match connectors. Have you ran into the "wrong" connector ?
Superseded parts can mean Honda updated the part to perform better or to save costs (among other things), or it can be a new parts manufacturer was selected to make the part (many times this is the case), but the specs and wiring connections should not really change as far as fitment on vehicle. Trim levels, country where it was manufactured, coupes and sedans can all have different parts numbers (and wiring connections) and that is where aftermarket parts makers/sellers sometimes get it wrong and it can cause confusion.
@@BigDog50001 I found the blower fan (TYC) on Amazon and ordered it before checking the connection knowing returning it through them would be easier if I had to. In this case, the connector TYC shows matches the car so I should be good.
Hi there.. I just bought a Honda accord diesel estate MK 7 2005 ) steering wheel on the right hand side!!). I noticed that the pax side heating works properly in all modes but the driver's side gives some very light heating (nothing compare to the pax side).
I did the following:
Hot water valve (engine compartment) removed, checked and refitted... works properly
Both actuators removed check and refitted.. both work properly. The groove of the driver's side actuator (the problem side) was also tested manually, from what I can hear the flap connected works properly too but engaging the groove manually (without the actuator refitted).. doesn't solve the issue!!
Any ideas as to why is happening this? thanks
Good job 👍.
Thanks 👍
Thank you!!!
No problem!
Dave as usual another good Honda video. Rule #1 don’t tap item until you start filming Lol. If. The A/C brings the shop down to 90 degrees it must be hot outside. Surprised you don’t take the summer off. Anyway hope you and family are well and drink plenty of water. Oh and Hondapartsnow.com are excellent to do business with. They answer all my questions promptly. Artie 😊😊😊
I order from them at least once a week. Yeah, it gets pretty hot out here thanks for the comment!
Fan wasn't working on my 03 honda after watching this vid I tapped on fan underneath the glove box a few times an fan turned back on. Now I know that it is the fan going out now lol
👍
I would like to change the cabin filter in my 1998 Accord. Someone told me it requires removal of 18 screws and sections of the dash. Any truth to this? Thank you also for your video.
I don't remember how many fasteners there are but yes they are a pain to get to.
❤❤❤❤
👍
Could you please help me with my situation? Honda Accord G7 2004. Fan blowing ok at speed 4-6. At speed 1-3 fan working 3-4 seconds then stop for 10-14 seconds, then start again.
Hard to say without seeing it. Control unit problems, bad blower motors or transistors can all cause problems like that.
@@BigDog50001 thank you for your answer. I'll go check at Honda today.
@@BigDog50001 done. It was burned out thermal fuse inside transistor module. 15$ and everything ok now :)
Seems like you have a person like i do that instantly hits the thumbs down button whenever you upload a video. Damn haters lol
Probably the same person!
Suprised the new blower motor came with with squirrel cage
Denson makes 99 percent of parts for Toyota as well as Honda and a few other companies
Do the same in the Honda civic
If I get one in that needs it I will try and record it.

waduhhhh kenapa bisa marah yaaaa
