Green 2001 XJ owner here, with 204,500 on the odometer. You just helped me a lot in troubleshooting an identical issue. Every window went up and down except the driver's. I put the test light probe one at a time on the two wires going to the regulator motor, and sure enough my switch assembly was not the issue! The light in the probe lit up just like in your video. Ordering a new regulator assembly now, thanks!

Best comment all week! Thanks for sharing.

[@hawkie333]

Excellent tutorial in basic troubleshooting. This basic process is used in everything, even Space Shuttles

[@harvestblades]

Great video & a perfect example of why a multimeter with a magnet is super handy. Those test lights are worth their weight in gold as well.

[@Donnythelatemodeltech]

👍

[@halj0rdan]

great videos on XJ. How about doing one for replacing alternator.

[@Donnythelatemodeltech]

Thanks, I might have one in the playlist. kzbin.info/aero/PLBkNUwyx9olF_GmEwSos5dsKLQGnVo6nM

Use back probes instead of stabbing wiring, can cause issues down the road.

[@harvestblades]

The wiring running from the door into the cabin used some ghetto wire insulation which was prone to cracking in the boot causing a short. That is a common issue on the XJ & YJ.

Give me f****** roll-up Windows any f****** day

[@ambivalentdisaster673]

Did you ever do a video on replacing the motor?

[@jarrodmunder]

Thanks for the video, it is very informative! I have what seems like a strange situation where both wires are showing 12V when I press the switch up and no voltage when I press the switch down. Do you have any idea what would cause that? Bad switch? What's also strange (to me) is that the window won't move in either direction. Maybe a bad switch and a bad motor/regulator? Any thoughts are appreciated.

[@jarrodmunder]

Follow up, even though I was having a different issue, I took the idea from this video (kzbin.info/www/bejne/g3OxenaVZ62SgLM) and decided to take apart the switch and resolder the connections and it fixed the window!

[@volatizee]

recommendations for cheap multimeter? maybe an affiliate link

[@aflykidfrombrooklyn]

Great video. Thank you. In the market for a computer safe test light but unable to find one that connects to cigarette lighter. Can you share where you purchased it or send a link? Thank you.

[@Dayton_EZ_Androsoff]

Thank you

[@Donnythelatemodeltech]

Welcome!

[@marcususa]

Can you post a link to where you replaced the motor?

[@garrettdoesnothing]

How about if the window only works like half the time. Some kind of loose connection I’m assuming

[@Donnythelatemodeltech]

Broken wires in the door jam

[@jdssurf]

That’s what I got too, also driver side door lock, if I reach across and flip the passenger side, it makes the driver side work again

[@gregorysoddworld8975]

Does your fuse box indicate which fuse goes to which operating unit?

[@Donnythelatemodeltech]

No sure

[@tantheman3359]

My windows will go down.. sometimes not all. And then they get stuck like that and it's been impossible to get lucky and get it up like before what could that be all windows all switches

[@WagwanHappyPappyHapPap]

The only time my driver window goes up is when it sits outside in the sun in 80°+ weather lmao

[@henryhaworth1743]

Why is it allways the driver side lol

[@JJBanuelos]
