“Yeah she threw a rod” had me rolling 😂 thanks for the laugh
You're killin' it lately, Eric! Spoiling us with all these videos.
Totally agree it's been brilliant 👍
I agree I needed ole Eric when I was young and dumb!! Ha Ha Still dumb!!
Lesson learned: "Test both the resistor and the blower motor"
Mechanics have it so easy these days. I spent Sept 1970-May 1974 in the Oldsmobile final assembly plant in Lansing Michigan. It was a hoot watching my co-workers assembling the dash. It was face down on a special support, and they had free access to everything from any direction. To assemble the dash they use custom-made tools to snake wires, and cables through the rats nest. Thus, even if your mechanic pulled the dash completely out of the car, they would never ever be able to complete some repairs without those special tools. I will bet only the dealers had access to those special tools. But I don't know.
Eric, I've sat in 100's of those design review meetings over the past 40 year as a design engineer. It usually goes like this...
Engineer: "We're going to use a 6mm hex head screw, it's a common size"
Purchasing Bean Counter: "We can get 5.5mm hex head screws $0.001 cheaper"
Boss to Engineer: "Change it!"
You need to whack the bean counter over his 'computer' to give him a reboot.
I can’t believe I just needed to order a 5.5 deep and 5.5 wobble to remove the ignition assembly thinger I in my Ford Escape. Does a socket set come standard with a 5.5? Nope. So Ford must be collaborating with socket manufacturers to sell 5.5s. Or not
100%
@@marksd5650 not just Ford, I remember Saturn also used a 5.5mm socket for its ignition switch
Just use a 7/32 I've yet to purchase a 5.5 never had an issue
Be careful on Fonzie! This younger generation does not know anything about Happy Days 😂😂🤣🤣
Fonzie - Henry Winkler - is 76 years old now.
Da Fonz does not grow old! Ayyyyyyhhhhhh!
@@flagmichael did you know his full name was Arthur HERBERT Fonzarelli. I had no idea his middle name and I don't recall it ever used in the 255 (11 years) episodes
I love my SMA hoodie. Warm and I’m flying the colors!! Get one today!!
Thanks Eric for a great video. We know it takes time to make them, and I’m pretty dang sure we all appreciate your efforts.
Be safe. And Cheers!!
I feel your pain from the gut feeling. To get paid for actual diag time is almost impossible in my neighborhood. One shop I worked at always sold the resistor and blower as a combo. Truth be told, I didn't mind. I hate just throwing parts at cars, but being under most dashboards is difficult. I'm a big guy with broad shoulders, I don't fit well under most dashboards. I also have had my neck bones rebuilt. If I'm going under, I don't mind replacing them both. As always, your videos are my top clicks. I only watch other channels if the repair is relevant to something im working on. Just know alot of us was feeling the pain of being crammed under there.
I'm sure Eric is thankful he's not a big guy as I think he's at most 5'10" and wears a medium to large shirt/hoodie, so even then, it's tight under there and I've had to deal with being under my dashboard and yes, it's no fun at tall for anyone, but more so for the bigger guys, especially the more broad shouldered, barrel chested ones.
Throughout my career as a master technician with Ford, Lincoln and Mercury I always sold the blower resistor and blower motor assembly together. It’s an excellent insurance policy.
I had a feeling it was the blower motor all along. That is simple repair and easy to get to both those parts. Now I had to change my blower motor on my Mercedes Benz 1987 300TD. That is a tough one to get too. It is just in front of the firewall and you have to remove a lot of stuff to get to it, like that wiper motor. Now the Resistor is under the blower motor and that is a real experience to get. Now I see why a shop would charge like $900 to change out a blower motor..
I love your comedy while you work. I love your bashing of auto engineers. 😀👍. Bob. From Florida
You're awesome. You made a 25 minute video about a heater fan and it's highly entertaining.
In the 1970s I had Snap-On screwdrivers with a hex on the shank for putting real torque on it. The hex size was - you guessed it! - 5.5mm. I had a 5.5MM Snap-on combo wrench to work with them.
BTW, the resistor pack has more than the resistor(s) in it. They include a thermal fuse - it opens when it gets to a specific temperature and doesn't care much about current. Who wants a fire in their ventilation ducts?
With a PWM signal, that "resistor" was likely a power transistor. Usually, power transitors have an inline thermal fuse that blows. Replaced one on a 2004 Honda Pilot. No where in the manual did they tell you about the fine mesh over the blower intake that was in the driver's footwell. Previous owner had had small dogs, so there was a felt built up over the intake.
Couldn't understand why a PWM driven motor would need a big-ass resistor. Thanks for the comment.
@Bret Agreed, and I still wonder why a transistor that should be saturating would need a heatsink that huge (30W?)
Exactly. And 99/100 a power transistor is going to fail short . Which is to say the blower will be full on. If it's not, then go looking for that thermal fuse if you have the time. If you don't have the time and it's not your car, follow Eric's path of replacing the parts.
That's nuts!
I take it you mean a non reset-able thermal fuse on the heatsink?
Either way, the only purpose of that would be to protect the mosfet from getting too hot. Why bother if the thermal fuse is just going to disable the PWM driver anyway?
Some designs man, really make you wonder.
If it were my car, I'd build a board with a fet bolted to a heat sink and a gate driver, stuff them in a box under the dash and know that I never had to worry about it again.
thanks 'cause i wondered how a "resistor" would be used in a PWM application.
It took me a moment to appreciate the Fonz quote, ha ha ha. The way he would bump the soda machine and get a drink was legend. Most guys who watch here weren't born yet.
I was thinking the same thing, lol
I remember watching reruns of Happy Days when I was a kid. Im almost 40.
"Threw a rod" made me laugh. I like your chatter.
Thank goodness for winter time more SMA videos for your viewing pleasure
Read the title too quick though we were in for a BLOWN motor 😂
It amazes me that people don’t even have enough respect to clean crap like crona equipment when dropping their car off for service.
Just think what their house looks like from the inside!
Agree, I usually throw all my garbage away at the gas station. I'll usually even go to the carwash and hit it with a degreaser if necessary
@@markkrispin6944 My dad and Grandpa ran a small HVAC company when I was a kid. The stories they told...
@@mattpobursky850 oh I believe you!
@@mattpobursky850 Yep, I occasionally watch Steven Lamoniere (sp?) here on the Tube and he serves customers in his HVAC/plumbing business that are like that, live in not quite abject squalor, but some come close in the south Boston to the SE corner of the state and many are as he calls it, not Taj Mahals or mutters it's a "shit show" as far as their residence is concerned. Mind you, many elderly and many are at best working class types.
Love all your videos Mr O. Keep up the good work 😉
A cabin air filter is a must to keep clean. I have changed my share of resistors and blowers.
I just delete them in my cars. Complete waste of time.
Yes, Eric O., that's exactly how it went down! The birth of the 5.5mm socket finally explained.
I would have seen power at the blower motor, figured it was the only problem, replaced it and then found out afterwards that the resistor was bad, too. I'm used to the GM thing where if it was the resistor only, the fan is stuck on high. I've never seen both bad, but I get how and why one can cause the other to fail. Great video - thanks for posting this!
Kicking ass putting new video's out!!!! Love it...
Love the content, seems like your doing more videos and I love that. I feel I am always learning something new from you.
The Neutral Drop reference at the intro was well done!!
Dang your on a roll with putting out vids lately! Keep ‘em coming!
Thanks for sharing this experience. I learned something. 👍
Always a good day to see you figure it out, twice…haha. It needed all three changed out and you knew it.
You getting us spoiled with all the uploads 💪💪
Again, thorough as always!
5.5mm is actually a very common head size in my experience. It's the default size for M3 nuts. When your screw is only 3mm, 0.5mm is much more significant then when you have a fat M10 bolt.
Randomly used on Generous Motors Resistors too
Once again a great class for us DIY guys Eric. I channeled you the other day when I used my meter and power probe to assess why my "speed control" which is what Ford calls the cruise control on my mint 2001 F-250 Superduty 7.3 was not working. I traced it down to a crusty plug connector on the master cylinder switch. Removed it, cleaned it up with CRC Electrical Connector cleaner, tested the two 2 amp inline fuses (this was a recall replacement fused jumper harness). Fuse #28 was good, I watched your 2015 video on clock springs. Ran through all; the other possibilities like power and grounds, horn function, speedometer function, rear ABS speed sensor (no ABS light illuminated) No air bag check light illuminated etc. Decided it was the cruddy plug. Problem fixed. I was about to do the clock spring dance... no. need as the cruise control came right up as commanded and all the other steering wheel controls were working normally. Thanks Eric for all you do for us. You are at the top of my list of favorite RUclips Instructors. You are entertaining, your wife is a wonderful lady and your filming and editing along with your instruction are first rate. I live on the other side of the continent in WA State. Otherwise I would bring my vehicles to you for things beyond my level. It would be fun to talk to you face to face sometime and thank you in person for all your videos. Please keep the videos coming as they are invaluable. An honest quality mechanic can be a hard thing to find. I had one but colon cancer took him away early in his mid 40's. I miss Mike very much.He was honest and talented to a fault. Now it's me with your tutelage. I'm even making my own how to videos as well. Thanks again Eric. Oh... and I am wearing out my SMA Hoodie. :0)
Good path to a complete repair Eric. 👍
Another great video! We are really getting spoiled with all these videos! Don’t stop now! 👍👍👍
I enjoy your videos they are full of useful information!!!thank you
Another epic vidja Eric. The diagnostic theories and practices that people learn here are amazing. Almost as fun as vids that have lots of ugga duggas! Thank you Sir.
I enjoyed the whole process. Thanks.
Excellent job. Well done.
Love all your videos and how you go after wiring issues
Hey Eric O, been watching your channel now for a year...thanks for sharing your videos! I'm an aircraft mechanic by trade and a DIY auto mechanic on the weekends. You've taught me some tricks that have made the job easier...even on the jets that I work on. I also live in the rust belt, Minnesota, and my next investment is going to be a torch.
Looking forward to getting my SMA hoodie. I will wear it with pride in my hangar.
I agree 👍 💯
You r an absolute champion cobba,enjoy very much what you do
I would like to thank you very much for putting on these videos very entertaining and the chit chat between you and mrs o
As usual Eric you're the king of the electrics and you checked it before you replace the parts that's a best thing about you and you did it good and look at that disgusting looking cabin filter tell that customer change that filter more often .
great work as always
I enjoy watching you man, you take pride in your work which is ver respectable with how many bad and shady machanics there is and on top of that you crack me up with the dad jokes and mechanic jokes all around good people and run a great shop. Keep up the great work and positive attitude. I just did the blower motor in my 97 silverAdo.
Another great video. Thanks for the lesson.
Like always great repair, I had replace the resistor on a trailblazer after I check motor was turning on the fan. Awesome content on the video. Take care thanks 😊
Good stuff!! My retinas are doing fine thanks for asking.
Great video Eric. That's the first xterra I've ever seen with a stick shift.
Thanks as always, Eric!
Find one thing broke and hope you got it. Find a second thing broke and know you got it. Now that's how most of my projects go. Reality at South Main Auto, gotta love it.
Eric you forgot E, when I still was a
tech at a Buick Pontiac dealer I had
a Grand Prix with the same problem,
the blower resistor was burnt out and upon further digging I found the
AC drain was clogged and the condensation leaked into the passenger floor board burning out
the resistor!! Spiders love crawling into
the little rubber boot covering the
drain tube!!! Nice work Eric!!
Love the video Eric very good job very informative
Another solid entertaining repair!!!
I like when you work on Nissans. A rare thing in your part of the woods!
Thanks for the info.Have an idea now where the resister might be in my Nissan Frontier.
Great video right on time. I'm struggling with blown resistor on 02 Dodge Caravan. Going to look a little farther than the resistor this time. Wishing you Happy Holidays. Thanks for Sharing!
Keep up the good work!
you could have got the power probe out and showed the people , apply power and ground no whirly gig . your a great instructor ! learn from you all the time thanks
That's such a cute little ratchet and yes the 2000 Silverado has side-by-side cabin filter, mine does. Great video Eric O..
i was worried when you dident check the blower motor before you sold the job ..been there done that and still do from time to time glad to see even you make mistakes i have been doing this for well over 30 years and not to blow smoke up your ass but you seem to be a great honest technician and business owner ..count your blessings (and i am sure you do ) with that awesome family you have
I love it when bit of a detective investigation lol .
A video a day ! santa bills bit spendy this year ! lol .
Have fun . content always good in humour and professional tips .
Made me smile. Normally if the blower does not work it's the blower motor. :-) Enjoyed watching.
Yep going with your guts up sometimes is the right way to go But Eric you know what they say that's why they put rubber at the end of the pencil because everybody makes mistakes. At least you're the honest guy that will admit it. Many blessings to you and your family during this holiday season.
Thank you for your attention to camera angles, it’s definitely not easy doing this without a video recorder, but with it, just makes it that more difficult. Thank you sir.
Really like this hombre. Trouble shooting excellence
"Do it like you were working for your mother." Love it Eric.
So entertaining. Keep it up! Helped me trouble shoot my 2010 Xterra OR
Another great video, thank you.
I've had luck with lubing the bearings/ on a blower motor and brought them back to life, But that was on older vehicles ..
Was watching a u tube video changing the the cabin filter on '01 Silverado. Thought to my self maybe that's why the system isn't working well. Didn't even know it had one. Took it all apart, sure enough it was plugged solid. Changed it out works good now I've had the truck 15 years and I think this was the first time it was ever changed.
really enjoy your videos.watching from england.R.Parker USAF MSGT Retired. Thanks
Thanks Eric 'Heeeeeyyyyyyyyyyyyyyyyy' 👍👍👍👍Fonz from Happy Days' and Merry Xmas hols' and Happy New Year to You and the South Main Auto shop and families 🥳🥳🧑🔧☃🎉🎊🍻
Loved the flash light as a push bar / hammer, application.
Well done Eric!
🤣 Good video as usual. The hilarity is part of the reason I subscribed 🤣
My favorite blower motor resistor story: my '99 Camry. Blower motor had a bad bearing, so it made a horrendous racket on high, but was fairly quiet on the other three speeds, so I didn't really care. Then, the blower motor resistor fails about three years later, leaving me with ONLY high. Down to the Auto Parts Box Store, plug that puppy in so I could have heat without deafness but didn't bother actually installing it - I left it hanging under the dash for the ten minute drive home.
The new blower motor resistor lasted almost two minutes before it failed, leaving me with no motor operation at all. It was a cold drive home for a stupid mistake, and when I got home I heated up the soldering iron and re-flowed the solder on the thermal cutoff (it was merely two metal tabs soldered together) and did the RIGHT THING - I installed it as it should have been, where airflow keeps the thermal cutoff intact.
Two years later, it still works, and yes I did end up replacing the blower motor when I had to start doing the tappy-tap to get it spinning.
Another fine job by a good mechanic that motor does sound like a turbo
I had an older Ford Taurus with a runaway blower, full blast. Glad I had a service manual with schematics because I had no idea there was a resistor that controlled speed. Quick, easy, cheap fix (way before YT). I’m sure your video will help a lot of people.
This video catches me this morning as the same time I get in my 2014 Dodge Durango and the fan just blows low. My conclusion is the resistor too but that’s because it blows only low. Seems easy to get too as well.
Perfect. Now when mine packs in I know how to fix it!
Kudos for trying the resistor first, then blower motor.
We must be on the "nice" list, cause Santa O is givin us lots o that sweet, sweet content this week!!! Thanx Santa O! xD
Safety rules require the blower motor to work on high speed even when the resistor fails in order to defrost your windscreen. Oh, try changing the cabin filter on a Volvo S40. You have to remove the electronic accelerator pedal. So much fun.
I think you're exactly right about the 5.5mm scenario! If there's a way to complicate a repair (crab assing it into a spot a contortionist can't reach) or adding more specialized tools, the automobile (not exclusive to automobiles) makers will find it. I think they start out the design process focused on deterring easy maintenance! After working on my own rigs for the past 45 years, that is my conclusion. Another great vid, Eric! 👍
Car design 101, take an engine. Then build the car around the engine. Don't worry about having to service the engine or anything else. Just jam everything around the engine.
Shit, we built the car and forgot the battery, there's no room left for it?!?!?! Hmmmm, stuff it in the fender-well.... aka Chrysler BS. lol
Remember when you could open the hood ant there was an engine there, now you've got to get past the pointless engine covers. Why?
@@watsisbuttndo829 Mice love chewing electrical wire (plastic coating has a soy content), so why not build them a roof for their "house"?
super patient great smart mechanic.
Well done Watson.
Keep it up Eric.
I have an 08’ F350 I pulled the Fonzerelli on 4 years ago, I have a 150.00 blower motor in the basement waiting but it’s been working ever since ! Lol never underestimate the Fonz !
Eric is one of those guys that you could bring ANYTHING to, and even if he's never seen one before, it wont take him long to figure it out. He HAS the "mechanical instinct" that was nurtured by DAD. MUCH RESPECT SIR!
Most men have a mechanical instinct.
Some more then others.
Enjoying your Freudian references about mothers....deep...and hilarious...great video...keep on smashin them out ....love your work...all the way from Brisbane
Nice work! Man that two piece air filter, help me understand. Reiterates my opinions about working on Nissan.
Thanks Dr. O!
had to change the cabin filter in my 2011 altima over yonder in medina area, my fat fingers could barely manage to get it in all snug like, thanks for the content
9:33 is what made me like the video lol Also, a trick that I saw in another channel I think was AMMO anyhow they put a "plate" is about the size of the filer, under the filter to avoid dropping that trash into the blower or at the very least minimize the amount that falls to the blower
I'm too old to reach under the dash like that but we had a cabin air filter changed on a Nissan Pathfinder we used to have. It was horrible to watch but the tech was a good sport about it.
Good job man!!👍👍😎💪
Nice job Eric I just found location of the cabin filter in my Ford F-150 just thought of it by accident
