In today's Quick Tip Tuesday I use the AES Wave U-Scope along with an amp clamp to help verify that a blower motor on was indeed failing. This is a great way make a call on an intermittent blower motor, fuel pump, or even a cooling fan motor. -Enjoy!

Hi The best sales pitch is an unintended sales pitch ha!
Thank you so much. The blower on my 99 Ford Ranger works well for two or three days and then nothing. I tried it the other morning and nothing. Later in the day, I ran over a pothole and it started up strong. The next day nothing.
So a new blower the best solution?
What preset so you have it set too?
Thanks
I have a 2016 Jeep Cherokee and sometimes the fan will go from blowing full to barely any air through the vents and it's not in auto mode. This seems to be a common problem in the Cherokee from owners forums, would an open spot in the motor be my issue too?
Great lesson, thanks!!
Good diagnosis. Nice to see a mechanic using a scope.
Thanks for listening to us. Keep uscope training coming!
i love my u scope i use it every day . another shop came in last week with the same problem and less than two minutes i had a diag for them .love it
I got my uScope last week. Thanks for the tutorial and book recommendation!
also there is an adapter for uScope that allows you to view just the AC portion of the wave so you can really zoom in when necessary.
Great video Eric O
Juan is my dad's brother
Wow you have all the latest tools. Just curious how much invested in all your tools?
Very cool diagnosis and nice liitle scanner or whatever it is.
Crap Delphi blower…
Its great to see someone of your "automotive stature" embracing the uScope and giving honest opinions about a great product.
It's guys like you that make fixin' my stuff so easy. I just google my issue and get a gazillion yotube vids. Keep up the good work. BTW I put vasilene on my Liberty gas cap O ring and my 456 code went away also my 300 but I didn't fix that ? And I got my sticker ! LOLOL
Eric O Thanks so much for using the U scope. How are Mrs O's reindeer coming along? Have a good weekend. ❤️
Do you ever get any criticisms??
Or do you click the FILE 13 button, when they come in??
Hmmm, maybe I should start leaving criticisms, to see if they come thru or not!! Let's give it a try.
Your breath stinks!! U- scope? Try regular Scope!! It's minty fresh!! MRS O will love ya for it!!
Hey. I just thought up a commercial jungle!! You can have all rights to it!! No charge!!
At first I thought it was the switch malfunctioning.
Thank you Eric. Good job.
Good use of that neat 'scope.
400 smakaroo's for that AES pocket picture!!!! Holy Smolly!!
That cool. Thanks for showing me / us this motor diagnosis method.
gutted it wasn't a fuse
great vid
great tip
Just make sure your fan motor is not controlled by PWM. I work on heavy trucks that have fan motors controlled by PWM. But if you set them to the highest setting, you should have a 100 percent duty cycle.
AWESOME! THANKS AGAIN!
I wasted my money on the Auto Wave Single Channel Scope. Should have gotten that U Scope. Thank you again for another good video.
Man WTF is up YouTube I was subscribed to this Channel and when I checked right now it was unsubscribed 😡
bada bing bada boom.
Thanks for the videos.
Thanks, I have been using scopes for many years and I never realized that you could check a brushed motor in that manner. DUH!!! Makes perfect sense, rather than me troubleshooting every little connection for resistance/conductance and opens. Then after all that, still no solution until I tear down the motor and find the brush/commutator in shambles…
Thanks again.
Nice quick and to the point using the little oscilloscope, thanks
My wife's stopped blowing all together. Fuse was fine so I replaced the blower motor and it fixed it.
Should show what a good motor looks like. Rookies like my brother really struggle with wave forms and how to read and interpret them. Thanks for the great content eric. Ps jeep update lol
auto assumes a bad fuse/fusebox now :)))
Nice I like that tool
What brand is BIG Nasty ?
Thanks good info 😁
I took Eric's advice and ordered an AESwave U-scope and talked to Carlos. He was extremely helpful. I highly recommend, if you are going to buy the U-scope basic, seen in Eric O's video, that you call and place your order, 559-292-7851. Ask for Carlos, he will get you what you need
On my car the blower motor is dying. Few love taps gets it going until I hit a bump in the road which turns it back off. It either spins slow on high or not at all. Few more smacks gets it up to full speed but it quits after awhile. Not too fond since it died in Winter time here. But its easy to get at it.
Have an 03 Envoy XL with rear AC. The rear blower will not come on when I want it to. Sometimes it will just come on out of the blue if I leave the switch on (at full blast). after driving around for a few minutes Never works anymore at any of the slower speeds (except for a quick burp of air through the vents then stops immediately).
If the fan is still spinning a little when you turn it back on it will probably always "start".
