How to test windshield wiper motor 

Thanks, hope it helps!

I m trying to test my Windshield Wiper Motor for My car also

Did it work?

Most welcome

Just like I mentioned in the other comment: Red and black leads I made myself out of high quality test leads. My local electronic store sells it by foot, very flexible and 600v insulated. Crocodile clips also bought at the same store. You can search on amazon or any other electronic store will carry those jumper wires. White wire I found laying around on construction site, it's 18/2 size and mostly used for low voltage as door bell wire, etc.. Battery is Dewalt 12v, but you can get one from the car charger, car battery or any LED lights transformer that has an output of 12v DC. They really cheap, again any electronic store will have it.

Glad to hear that, Thanks!

That's normally the relay playing up

@@SkidsNDonuts Excellent! Thank you!

Both, positive and negative comes from battery.

Sorry I have no idea, I never needed a meter or to see how much current it's pulling. I just measured voltage to make sure you have 12v.

if you have power at the wiper motor and when you turning it to all different settings power still there in that case has to be the motor. Also check the Neutral cable, if that has bad connection all the way to fuse box, it will not work. You have to test power right inside wiper motor plug, to make sure you have solid ground and good power. I measured steady power and then all the settings on speed 1-2-3 and so on, to make sure you have voltage coming on those settings and speeds. Hope it helps!

@@biesasuk yes it helps a ton because now folks are talking about buying a BCM

@@jeffwatson151 Yes I would say test all pins first to make sure your plug works properly, specially on older cars, could be a broken ground somewhere and that would not work. If plug with pins has power and settings work then, has to be the motor. If settings don't work, has to be something with relays and more testing needs to be done. It might even make you to change whole board which is most likely very expensive, hope not!

I have labeled it on the sticker. which is which. there is 2 different speeds
