Thank you for the video. I followed it and I saved myself $500 dollars in dealer servicing. In the beginning I pulled the orange plug to disconnect the battery before working on the fan. I cleaned the fan using q-tips (dry first and then soaked with isopropanol) and some wet wipes. I found it easier to take the whole fan apart to get into all the nooks and cranies during cleaning.
Good video but you missed one important maintenance item. The black intake has a screen filter that gets clogged with dog hair. It is reachable under the right rear passenger seat. You might even be able to clean it with a shop vac crevice tool. (No 10mm needed.)
I told Merv Junior to get good shots, but he neglected to capture that portion of my procedure. I did mention it however. But I'm glad you pointed it out. Thanks for watching. -Merv Himself
the battery and yellow car icon comes up on my dash and I have to reset often. I noticed that it happens when it's hot and previous owner was a dog owner. there was lots of furs in the car. I might actually have a clogged up filter. I'll check tomorrow. Thanks for the video
I cleaned that screen filter out and emptied varmint hair from it but MY FRIEND still needs to clean that battery filter next to the DANGER Death ain't ideal hybrid battery. Is she good if she pulls the orange clip? Does she need rubber gloves? Help please?
I worked a bit to get that screen out and cleaned it up real good. And then I realized what you mentioned. Why not just reach under the seat with a vacuum cleaner hose. My screen was maybe 10% clogged after over 100,000 miles without pets and not many children riding along.
That is a great video. Thanks for the humor and showing us the frustrating parts too. The sound effects and graphics are superb. Folks will feel more handy by just watching. Thanks.
Hola Merv. I have a '13 Prius v and a '19 LE awd-e, which I think is the best bang-for the buck, cold-weather commuter car available. A nerdly point about which battery starts a Prius: "In all versions of the Prius, the motor called M/G1 spins the engine to start it. It is an AC motor powered by the inverter which is powered by the high voltage battery. However... If the 12 volt battery cannot start the computers and power the fuel injection and engine electrics (the spark plugs need to fire, etc) your Prius won't start."
@@MervsServiceSecrets : There’s a pipe connects to the fan and goes under the seat was dirty too. What doesn’t make sense is. Why air is sucked from under the seat? If I turn on the heat which I like it hot. It is blowing hot air on the batteries. 🧐🤔
I learned a lot just by watching since was just charged $293 for a hv [high voltage?] hybrid fan/filter service by Toyota and was wondering why it was so expensive. At least this makes me feel somewhat better than it does take some work to access the fan. Can you tell me what the vents are for that are located under the driver and passenger seats? I can't find anything in my manuals. I also was told to replace an AIR CONDITIONING CABIN FILTER (no price given) and an AIR FILTER, R&R--whatever R&R means ($135). If you have any videos on these filters, that would be great. I discovered what I think is the air conditioning filter accessed through a panel in the lower glove box--it looked clean to me so I'm not going to do it--I don't have pets and keep my car in a garage, so not much dust either. Thank you again for any input.
I think one of the things you are calling a "vent" under the seat is the passageway for the cooling fan. As for the engine air intake filter, you will see me remove the housing for it in the following video: ruclips.net/video/4ALjAsMKhCA/видео.html The housing is outlined in yellow, near the beginning of the video and you'll notice silver clips that can simply be released to open it up. (You won't have to take the whole thing out like I did in order to get to the filter)
so just to be clear on this, you do not need to take the side panel off on the normal Prius as well? The step you skipped. 4:35 mark. Yes I want the shortcut way. the non stupid way. the effecient "i'm not scared" way.
Nicely done! Isn't it a shame Toyota doesn't put a nut on that squirrel cage? You can always get a job as an announcer. I met a woman who sang & I was hypnotized with HER announcing voice. Most men want a woman who shuts up, but I could listen to her all day. 😅 I own a 2019 Prius & clean my squirrel cage w/qtips & toothbrush ALSO. E 15:26 njoy your humor also.

HI Merv, Gen2 Prius Battery Fan working. Found corrosion in Large Plastic plug connection, closer to the hatch. I tried electrical cleaner and used a needle to pick clean the corrosion. I wanted to wait and get a plug from a salvage yard then splice and connect. But I when't ahead and cut off the connector on both sides then cut and splice together with electrical tape. The wires were black, yellow, purple and brown. It looked like the brown wire was missing the metal pin inside the connector. I assume thats the hot lead. Did not work. I will try and find a good plug from a salvage yard and go it again. It may be that the wires have a short elsewhere. Any suggestions?
Wow. You are going where no Merv has gone before! Wish I could offer more advice, but you seem to have a plan that I wouldn't dare criticize without having more information. Be sure to post your project on social and tag me, so everyone in the MervServe DIY Club can check it out. On Twitter I'm @MervsService and on Instagram I'm @MervServe
I took mine apart before seeing the video, no one has any idea how to get a new one at the parts store… any idea what it’s called? They sold me closed cell weather stripping…
Merv Honey, you didn't really need to do all that with the fan. I was needing some close up shots of the filter on the other end of the vent, that's under the seat. I've seen some videos of that intake filter being clogged and was hoping you'd come through with a better one.
@@MervsServiceSecrets When Junior finally finds the spittoon, please get him to record that part? My 2015 Prius V has black interior, and I need to find that vent screen that hasn't been examined since I purchased it. Pretty Please?
Dear Merv and other viewers, I have a question about cleaning the HV battery fan on a Prius Plus Wagon (2012). The Prius Plus Wagon is sold in the US under the name Prius V. But..., there is one big difference when it comes to the spot where the HV battery is located in the car. In the European Prius Plus this HV battery is placed between the front seats. On the US model Prius V Wagon the battery is placed under the back seat row. From the outside the Prius V and the Prius Plus (Europe) look the same. Both are wagons. However, the European model has THREE seat rows. The European model is a SEVEN seater. The location of the HV battery is therefore very different. Like I said, it's between the two front seats. Would anyone know where to find information on the cleaning procedure for the European model Prius Plus Wagon? I could not find anything on RUclips. The air intake for the battery fan seems to be under the richt front seat for the Prius Plus. Are there Toyota service manuals for car technicians who cover this cleaning procedure? Thank you all in advance for your help, M
Thanks for watching. I am posting your comment in hopes someone with more knowledge than me can chime in. I really don't know much about that European model you spoke of, but whatever you do, be careful and follow all imaginable safety precautions. Do a lot of research and get tips from lots of professionals. Also, please update us if you find a solution and be sure to hit me up on social. Have you tried the prius chat forums? -Merv Himself
@@MervsServiceSecrets Thank you for your swift reply. I hadn't thought about Prius Chat. Thank you for that suggestion. On Prius Chat I found the link to a Spanish language video on the European Prius Plus+. It's title is "desmontar ventilador Prius". Link: ruclips.net/video/MCDHIsRGEYc/видео.html
There is a grate over the end of the inlet duct for the HV battery fan, but it's just there to keep out the big stuff. There is no filter which is why it gets dirty inside that blower. Look under the rear seat on the passenger side and you will see where the duct starts. From there, it goes back toward the HV battery and bends upward where it connects to the cooling blower. Hope this helps. Be careful.
Great video, Merv. I must say, you did make this look easy. My dealership wants $500 to do this! As others have commented, I’m a bit hesitant to do anything on my car myself - Toyota puts the Fear of God into you when you ask them about doing anything around the hybrid batteries yourself. I do have a question - is it necessary to take off the Orange ‘circuit breaker’ bar if you’re just doing this fan cleaning?* (*Asking for a friend who does NOT want to end up with a home permanent hairdo.) ✨😂✨
The idea behind that breaker is to reduce the electricity to a non lethal level. I personally fancy that as a nice feature. Dare devils may feel otherwise, I reckon.
no, the 12 Volt battery doesn't start the engine like a normal car!! Big mistake! The 12 Volt is simply for the lights, the fan, the indicators etc. The engine is started by one of the two electric motors in the planetairy gearset, which is attached to the engine
LOL! That toothbrush calling out your name really had me. Btw, the thing about Toyota designing 3 diff connector block designs in 1 place ain't for bull. That's a monkey-safe system to prevent any mix up.
For any watching, toyota recommends NOT having the fan spin like he did with rhe compressed air. It apparently can break the fan. Hold the fins gently, spray, and move it a little. No free spinning.
Okay, so you were able to touch everything that you did...using a metal socket, etc. because you pulled the orange prius battery tab which decreased the voltage (and danger) and also I assume because you are wearing rubber fingered gloves? I have ...a friend...trying to clean her car after a family of pernicious varmints tried to make a home (with a full comfy varmint nest) in her glove box, her cabin air filter, some nice scarves she kept in her car in case she needs to look fancy quickly (ask Helen about how a cute scarf can make you look instantly more professional...er...I guess it depends on your profession), and finally made their home for their children also.. in her trunk. It's been a hellish road to clean up their mess but she's been able to clean & change everything out like the air cabin filter, the filter inside the cabin that filters the intake air located next to the back seat inside the cabin closest to the trunk.....but she needs to get to that battery filter you're cleaning here in this video Help? I've..I mean, SHE has got girl parts and she doesn't plan on getting bamboozled by a mechanic shop (who wanted to charge her close to $100 to change her air cabin filter behind the glove box which took her about 5 minutes to remove and change youtube DIY style by herself.) What gloves are you wearing? Will she die?... She (and I) are mere mortals. They also want to charge her $119 to make sure her car is okay to drive 14 hours. Her belts are fine (that's what she said). Filters changed, oil changed recently....what in the world are they checking for for "road worthiness"? This car is fine to drive as she drives it just fine without trouble. 2015 Prius with less than 56,000 miles. Most importantly....How does she clean that battery filter you're cleaning there without getting electrocuted??
Well, the purpose behind that orange disconnect is as stated. But of course as a general rule, don't do anything you aren't comfortable with. The best I can tell you comes from personal experience -- I have never died doing it, nor have I heard of anyone dying in such a way. Yet I always encourage viewers to do additional research beyond whatever information they glean from my videos. And regarding gloves to wear, that brings us to a very special video Demille recently put together which demonstrates various kinds of gloves if a person really wants to take things to extremes. In this video , you will even see special electrical gloves that are recommended when someone is taking apart all the most dangerous parts of a battery bit by bit, although I suppose some might argue they are overkill for minor procedures. But again, you need to decide what's best for you. You'll find the video here along with important references to Mr. Weber. I think you'll like it. Hope this at least helps to point you in the right direction: ruclips.net/video/g12Z_PFihYc/видео.html
Thank you for the video. I followed it and I saved myself $500 dollars in dealer servicing. In the beginning I pulled the orange plug to disconnect the battery before working on the fan. I cleaned the fan using q-tips (dry first and then soaked with isopropanol) and some wet wipes. I found it easier to take the whole fan apart to get into all the nooks and cranies during cleaning.
Glad it helped. Sounds like you did a good job. And I like your attention to safety details!

I just found it. It was completely clogged.

@@MervsServiceSecrets : There’s a pipe connects to the fan and goes under the seat was dirty too.
What doesn’t make sense is. Why air is sucked from under the seat? If I turn on the heat which I like it hot. It is blowing hot air on the batteries. 🧐🤔
I know what you are saying, but I reckon they figure cold air falls and hot air rises, so sucking it from the lowest point is best.

Men do you need to disconnect the negative 12volts battery terminal befire doing this job?
Wouldn't hurt.
You make this educational and entertaining
The 12 volt battery doesn’t crank over the car, it powers the computer that controls the Hybrid battery which cranks the motor in the hybrid transaxle
so just to be clear on this, you do not need to take the side panel off on the normal Prius as well? The step you skipped. 4:35 mark. Yes I want the shortcut way. the non stupid way. the effecient "i'm not scared" way.
Not sure becuase my prius has is the "V". For victory. ;)

Typically I have noticed they come on when the battery reaches a certain temp.

For any watching, toyota recommends NOT having the fan spin like he did with rhe compressed air. It apparently can break the fan. Hold the fins gently, spray, and move it a little. No free spinning.
