Testing A Chevy Blower Fan Stuck On

[@th7480]

Excellent video. You stayed on point...... No shuddering, no loss of words, no awkward pauses, and no rambling on about the history of blower motors or why they were invented. 👍

[@mikeyg3002]

Love that you actually explained everything and how in depth you went. I've used your videos many a times for various vehicles. Keep it up 🤘

[@GoTechTraining]

Hello, Thank you for the kind words and taking the time to comment! Glad to help out! ~Ryan

[@attaallaabdalla439]

nice work. just a suggestion to show where you place the oscilloscope probes on the car

[@richardmitchell7836]

Definitely, good info to keep in the back of the old noodle got to say I haven't seen stay on like this, until now. I always look forward to your videos, thanks.

[@scientist100]

It is a new design in trucks from what I have seen. They are pricey.

[@GoTechTraining]

Hi Richard, Thanks for watching, glad you liked the video! ~Ryan Wilsing

[@josephremache3721]

Nice! Could you point out on the diagram where you are back probing your leads?(for future videos). Love your videos. Thank you for sharing ur knowledge

[@GoTechTraining]

Hi Joseph, Will do! Thanks for the kind words and supporting the channel! ~Ryan Wilsing

[@bernardaflores1720]

Tacoma's like to burn the blower motor resistor too. Nice video!

[@GoTechTraining]

Hello, Good old blower resistors! Thanks for the support! ~Ryan Wilsing

[@bobgall863]

Aways good to see the actual fix .

[@GoTechTraining]

Hey Bob, Thanks for watching! ~Ryan

[@cpcoark]

Good video. Learned a new way they control the motor.

[@GoTechTraining]

Glad you enjoyed it! Thanks for supporting the channel! ~Ryan Wilsing

[@nlwin7789]

Nice job at diagnosing and enjoy the video. Seems resisters whether old school or integrated keeps popping up with problems.

[@GoTechTraining]

I agree! Glad you enjoyed the video! Thanks for reaching out ! ~Ryan Wilsing

[@calholli]

All control mechanisms have a limited shelf life.. Even the light switch on the wall of your house, the solenoid on your starter, the relay running your fuel pump, the headlight switch behind your steering wheel.. etc. etc.. When you're dealing with something physically making and breaking contact while the power is still flowing through it, it will always arc and spark, and get carbon build up over time.... One of the only things that doesn't do that is power through induction; For example, when you set your phone onto a wireless charger, it starts transferring power without ever turning on a physical switch

[@duanedonaldson2262]

My guess is that the pigtail is not for a new design? but maybe in preparation for an overheated pigtail that is discolored? Thank you for the video. I am also wondering if what you called the resistor is actually the blower motor processor on the schematic since the head unit controls the speed via PWM and not a set of resistors like the old-school units, cheers.

[@GoTechTraining]

Hey Duane, You are correct, the blower resistor is called the processor on the schematic. Thanks for watching! ~Ryan Wilsing

[@RamyAshraf]

Great video as usual from GoTech, I have a samall question not in the technical part, May I know the program name you use to draw on screen, I see it's toolbar in bottom of screen but can't know it's name. thanks..

[@GoTechTraining]

Hello Ramy, It is actually part of the smart board I'm using, which is a Newline TruTouch. It allow us to connect our lap tops and draw on the board. I hope this helps and thank you for reaching out! ~Ryan Wilsing

[@philh9238]

Can you do video on can bus diag?

[@GoTechTraining]

Hi Phil, We have actually been thinking of doing some more system diag stuff. I will definitely put can bus on the list Thank you for reaching out! ~Ryan Wilsing

[@jerryaltmann1345]

What did you hook your computer up to or your multimeter?

[@ablackformula]

I wasn't expecting the blower motor "processor" to have its own 5v regulator for the hvac module to pull-down. Apparently it's more than just a resistor!

[@GoTechTraining]

Hello, I wasn't either, I originally had the blower processor disconnected and was looking for a signal output from the HVAC module. Pretty cool system! ~Ryan Wilsing

[@scottlofton2607]

I'm having somewhat the same problem. Changed the blower module and the head module and it went through the program but the fan is still running when you turn off the key. Any thoughts?

[@aivarinno9257]

Diagnose, not just swap parts. Simple.

[@scottlofton2607]

@@aivarinno9257 Yes, I bought an O E M blower module problem sloved. Cheeper after market parts can sometimes cost you more in the long run

[@calholli]

Next time it would be nice to see you pull the resistor apart, just to see what's actually inside and how it works. Cheers.

[@GoTechTraining]

Hey Calholli, Good call, it would be cool if you could see the issue I might have to try and cut that thing open Thanks for reaching out! ~Ryan Wilsing

[@mikechiodetti4482]

Nice video. Good explanation.

[@GoTechTraining]

Hey Mike, Thanks for checking out the video! Glad you enjoyed it! ~Ryan Wilsing

[@Bobbygale121]

Good information, Thanks..

[@GoTechTraining]

Hi Robert, Glad you enjoyed it! Thanks for watching! ~Ryan Wilsing

[@scientist100]

Had this happen on a Ford Transit Diesel if I recall correctly. Those resistors are expensive.

[@GoTechTraining]

I agree! If the blower motor is drawing excessive amperage and needs to be replaced also this repair can be really expensive Especially for a system that works, just won't stop working! Thanks for watching! ~Ryan Wilsing

[@juanalcantar9781]

Seen it a few times on older gm with outs air and one Nissan Quest

[@GoTechTraining]

Hi Juan, Cool, haven't seen this issue on a Nissan before! Are those the vans with the blower motor in the middle of the dash? Thanks for watching! ~Ryan Wilsing

[@DependableAutoTruck]

what i like is my 1994 ram 2500 has a knob that controls how hot or cold. a knob that controls speed it has a resister also but there aren't any computer controls controlling heater and guess what i have good heat and good ac and so easy to work on heat without a computer how can it be. its wonderful

[@GoTechTraining]

Hello, Heated seats, cooled seats, multi-zone systems, it will be interesting what comes out next. But like you said more computers, more complex and more chances for failure! Thanks for reaching out! ~Ryan Wilsing

[@penrithautoelectrical1942]

You know what actually would be great. To Diagnose the fault the old fashion way not using a scope.... Do a Video on that. Basic Diagnostics.......

[@GoTechTraining]

Hello, We do use a multimeter in the video, and show the difference in readings between the scope and meter. I agree a scope does not have to be used to get a diagnosis on this issue, but it is nice to see a clean pattern from the hvac control module. Thanks for reaching out! ~Ryan

[@rickowens4397]

At 4:55 you say it needs a blower motor resistor... a minute later, 5:58, you say it needs a processor! hmmm?

[@GoTechTraining]

Hey Rick, Sorry for the confusion, the blower motor resistor is called a processor on the wiring diagram due to it being a auto system. They are two names for the same part. Thanks for watching! ~Ryan

This was good but I feel like this was for advanced mechanics already. didn't show where the wires were hooked up or what the repaired wire is supposed to look like.

A square wave is square; in other words, 50% ON TIME and 50% OFF TIME. That is a Pulse Width Modulated Wave; the ON TIME and OFF TIME changes as commanded.

Hi Greg, Yeah this one wasn't too bad, using a solid state module keeps the circuit pretty simple. Thanks for watching! ~Ryan Wilsing
