98 740iL - Wipers still not working

We replaced the relays, and the wipers still don't work. With the old and new relays, there's no sound at all coming from the motor. Anyone else have any ideas? We're hoping it's not a bad motor. With losing my income and our rental house (we've paid our rent on time every single month, our landlords just suck) both within about two hours of each other (****ing fantastic day last Wednesday was), and, in another month being homeless with a toddler, we really REALLY can't afford to be spending hundreds on motors right now especially if the motors are fine and it's something else that's minor. Please someone have a miracle fix for us. Normally I love rain, but not right now, and we've been getting spring showers. We need a morale boost, and a cheap or even free fix would help with that.

And if it does need to be a motor replacement, any leads on one for less than $222 (Pelican)? We really don't have the money right now for that. We'd also need some sort of how-to for doing it. We're so frustrated and stressed about the possibility of losing our daughter (even is not having a home is temporary, as it will be for us, CPS takes toddlers away) and this is the last thing we need.

Do you have a Tester? To test the motor? or do you have somebody who will borrow it for you?

www.car-part.com is a great website to locate a salvage with your part. Keep in mind that if you buy used part you don't get your money back but you should get another part.

But first let's find what your problem really is...you really need a tester to do that. or some ingeniosity with a fused wire..

The tester that I'm talking about is something like this :http://www.advanceautoparts.com/1/1/...rt-cp7665.html

You could have a bad wiper switch or a bad wiper control module as well.

You need to find out if the motor gets power, if you get power to the switch and if the power goes to the relays. You can jump (with a fused wire) the relay to see if it will turn ON. If the module is bad in worse case scenario you could put the wiper on a separate circuit with a fuse until you get some $ to fix it right. Is not the end of the world....yet!

I was hoping you'd be around today You were a lot of help with the relays.

We don't know anyone with a multimeter. I just asked my husband, and off the top of his head, he knows no one who even might have one, and I don't either. At least no within about 450 miles of us. Our mechanically inclined friends are not even in this timezone. If this the point I need to slam my head against the wall really hard a few dozen times?

Check this image : You could jump with a fuse wire to see if the wiper motor will turn on.
So 1 is ground , you need to ground that
2 should be positive since is stage 1 and is coming from relay
3 should be positive since is stage 2 and is coming from relay
4 comes from the module ( the one who count the seconds between intermitent command)

Basically 1 with ground and 2 with positive should turn the wipers ON. To make sure , we just need that multimeter around or use a fused(7.5A?) wire. Don't use a wire without fuse , you might damage something.

Here is the complete diagram for your wipers. Check the fuses in the picture and jump the relay if needed.

Hey everyone,

I am hoping you can point me towards the location of the wiper motor some what I would be looking at to remove it. Thanks!
