How to Diagnose if the Window Motor or if the Window Regulator is Bad

Bro I use speaker wires and jumper cables really glad I found this video now because it started raining about 30 minutes ago hell is going to be raining all week I'm just glad I'm just glad I found it while it's still sprinkling my window only went down and would not come back up

Great video tho I think this job is beyond my skill level. Why and how does the cable get unspooled and tangled like that?

How in the heck do wind the wire around the pulley and get it back into the plastic piece so it will fit back into the motor?

Tip: if at some point you upgrade a battery which is still decent, trickle charge it, and pull it out when you need 12V power for bench testing.

Years ago I replaces a small Honda Fit battery with a Miata battery for winter. The old Honda battery has been very helpful (and its tiny.)

Great Video but I have an issue with calibrating the window up function. Every time I close the window fully it re-opens about half way. It is like it is going into anti-pinch safety mode each time I fully close the window. Any suggestions??

thank you for sharing. is changing the window motor difficult? on 2005 honda crv

Thank u it was perfect

Thank you for the excellent vid. I have to replace one of these tomorrow!

I have just liked and subscribed. Thank you! I wish all of my instructors were as clear as you are!

Hi, got a car whose driver side window won’t go down or up with the master switch but the rest if the windows are ok with the master switch buttons. All i can hear is a single click when i push down once or pull up. Coild that ne a window motor issue?

What if one window goes slower than the other one? I'm thinking in replacing the motor.

Just took off the door panel of one sliding door of my van. All I get is the click. Disappointed it might be the regulator, as I just had to put a new one in the driver’s door. BUT, now I know how to check the motor easily and can move forward. Thank you. Great video.

Best video I've seen so far explaining how to bypass everything with only a 9 volt battery.
You made it simple. Thank you very much for your expertise. As I've seen a lot of other videos and I knew there had to be a better way.
Seek and ye shall find

Well, you tested two good, working motors. What did you do about the tangled or broken cables?

My man, I haven’t been able to find any info on the problem I’m having. I have a 2004 accord and the rear right window was stuck about halfway. When I’d try move it any further, there was a crunching sound. I replaced the motor and encountered the same problem before I noticed that both motors were eating the cable covers. Have you ever seen this before? Do you know what my issue might be?

Thank you!

Hi my rear quater window won't open all I can hear is a click on that side everytime I try to open it what can it be? Btw the same switch controls the front which works

thamk you, your info helped me resolve my questions, knowing the motor would spin reverse by changing the polarity

You sound like raymounds brother from everyone loves raymond LMAO

what was the name of those pins you used when alligator clips wouldn't fit?

Nice video showing the functionallity. It doesn't give answer in the case motor runs fluently, regulator goes up and down but motor won't stop when it reaches extreme positions. That means: I should sense when l have to release the switch,because if not, the motor still runs and there is no thing to stop it. And the mechanism of winding the wire scratcheds badly it!! So I mean I successfully replaced wires, but the mechanism kills it for the motor doesn't know when to stop. Does somebody know what shoud do this duty? Any idea will be appreciated.

Why might my window only work when engine is running but not in auxiliary mode? Only one window does this.

My Toyota Runx Front electric window is not working there's a sound inside when you are pressing it down

The window on the back door will not close

Perfect and to the point! Thank you!

thank you it was very helpful

Your a Pro bro

I learned a bunch here ! thank you ! Have to diagnose a friends window. Could not have saved time without this - thank you !!!!!

What happens if you leave it connected? Will it burn?

So I bought a new regulator and motor assembly and did the test with the alligator clips and a 9volt battery and it didnt move it at all either up or down. I dont have access to a 12 volt car battery. Is it possible i just have a faulty assembly

My 2020 Chevy does a noise when it rains it sounds like grinding noise is it the motor or regulator? The dealer ship put some sealent but it’s still doing the grinding noise plz help :(

Thank you.

Outstanding! thank you very much. Well explained and viewed.

NOW ITS TIME TO HAVE MOSQUTO MESH TOO AS WHEN AC IS OFF NO FRESH AIR INTEK IS POSSIBLE

Nice video thanks man 👍

I'll be damned. Now I stop researching power probes; I just need a 9v battery and long jumper cables. Back to basics. Thanks a lot man!

Nice explain, only to alert, some models Secnic II have a encoder component and in case of replace the battery or low you need configuration the elevator like new from factory, you can se manual of use how can do it.

I hear a clicking noise from inside my passenger door and the window isn’t working so I’m pretty sure it’s either the motor or regulator. However the switch is also stuck from my driver side. What should I do first?

I thought my regulator was bad so I bought a new motor and regulator combined unit my passenger side window is stuck down I installed the new motor and regulator and the window came down and locked again I bench tested the motor and the motor only turns One Direction whether or not I push the window switch down or up do you have any idea why this is the case please help

I used your 9 volt battery to bench test my motor (2002 Olds Intrigue) and both directions functioned. Got the new regulator and motor back in (old cable was tangled on the spool), and now only up works, no down!! I have power to both at the motor wiring connector! I am so baffled#! Is there any kind of limit switch or ?? inside the motor? This video was super helpful to me, and made alot of sense.

My window motor makes a grinding, crunchy noise. I think it's bad lol

Great informative video. You did a very good job and I appreciate it. Subbed

Thank you! I'm going to try to bench test just the motor. I tried with the regulator attached, and got zip, not even a spark, which I thought was odd (tested it using car battery). I hear the motors are rarely bad, but if indeed it's bad, I guess it won't hurt if I start disassembling it (take out regulator cable gear). Everybody cross their fingers that I can figure this out!

great information....

I have a question, my passenger window has stopped working all the time for example if I lower my window and let go of the button half way and then try to continue lowering or raising it, it will not go up or down. The switch still clicks, sometimes It won't even go down at all. I have to close the door hard and for some reason it starts to work again temporarily, thank you!!

The power window on the left side driver door goes up and down alittle at a time and what would be my problem 2002 toyota tacoma prerunner

i've tried this on my astra with a 9v battery and no luck, will try tomorrow with a 12v battery. I used multimeter to on the wire coming from the switch and no power is coming from pin 4 . When I test on a working door, pin 4 lights up

Thank you for such a very informative video. You taught me something. Thanks.

Hi, I’m currently trying to figure out if my regulator or motor is bad. I followed the video and hooked up the motor to a 9V battery and nothing happened when I connected the positive to positive and negative to negative but when I switched them on the battery ( positive to negative and negative to positive) it started to click. Do you have any idea if that is indicating if it’s the motor that is bad? No movement, just clicked.
