I checked FAQs, prior posts via search of brickboard, and wiring diagram before posting.
1988 240 DL with 284k+ miles has windshield wiper issue. Slow, intermittent, and park work. High speed does not work at all. On the wire harness connected the wiper motor, green #53b wire has 0 Volts, the other 3 wires supply about 12 Volts.
#2 fuse is like new.
I presume that the relay is at fault.
However, I checked the wiring diagram and looked up the part number and color for the relay, but cannot find the relay anywhere in the driver's floor cabin area.
Where is it located?
Thanks

Do I have an electrical gremlin?
Yesterday, my windshield wipers did NOT work at all (though the wiper fluid nozzles worked). This morning, they decided to work, but only at low speed (even when put at high speed).
This morning, the radio stopped working, but the cigarette lighter (both fuse #1) was fine and the fuse had continuity. Removing the radio cover and reinstalling it fixed it.
The power locks stopped working this morning. Fuse #8 was broken. Replacing the fuse fixed the power lock problem.
The only intervention I did was the following: yesterday, I was detailing the underside of the hood. The courtesy light was dirty, but worked. I removed it and saw a spark. It stopped working. I cleaned and reinstalled it. Still didn't work. This morning, after replacing fuse #8, it resumed working.
What's going on?
Also, what's the easiest way to test for high speed not working: replace the windshield wiper stalk/lever or check for power to the wiper motor? If the latter, which color wires do I test (I can't understand the wiring diagram)?
Thanks!

Just go back to the beginning of this thread; the first reply you got. Use a test light or meter to trace what connections have battery voltage, don't check for "continuity." Double check, for power at the wiper motor plug: Green wire for in the fast position, brown wire for slow. Don't disconnect anything, and check with the ignition switch in KP-II.
The way to find electrical gremlins is to look for them while they are making an appearance, and tracing them, not by "testing" individual components.

Fuse #2 controls wipers, horn, and lights. There is continuity across the fuse and horns and lights work.
However, the wiper doesn't work at all.
I found the relay (#898151). I opened it and t tests fine and is without damage>
I switched out wiper stalks/levers with a junkyard, but that didn't solve things (albeit I don't know if the junkyard part really works).
There is no power going to the windshield wiper wire harness.
However, applying 12 volts to the brown and green wires (or any other combination) doesn't activate the wiper.
I disconnected the wiper arms from the motor and they move freely and withou squeaking.
Please help.

"So, what happened to the wiper action? Did the wipers work fine and quit on you? What happened? A slow quit or a quick quit?"
I had wiring diagrams and tested circuits before posting today's update. I opened up the relay and saw two solenoids (?) inside click when I added 12 Volts to the corresponding leads. There were no burn spots or loose solder inside the relay. The relay's external contact points were clean.
Wipers currently do NOT work in key position 2, but work for the horn and headlights. In these positions, the wiper fluid works perfectly.
I haven't used the wipers in a month. The only things I did differently were to change the wipers and lubricate the outside threads, per your suggestion in another thread.
At that time of my initial post here and when I bought the car, the wipers workd, but only slow speed worked.

Thanks.
I think that you posted that suggestion last week; if so, I have to credit you for that idea, which I did the other day before posting my follow up yesterday. In fact, I sprayed the top of the screw thread and added junkyard black plastic covers to protect the base of the wiper blades.
Just to be clear:
I switched out relays and wiper stalks/levers and the problem is the same (ie only on high the wipers seize on the up stroke).
I disconnected the wiper motor from the metal arms under the dash; the wipers move easily and without squeaking.
I removed the wiper arms from their screw base and lubricated them.
The wiper motor seizes only on the upward stroke and on high. Slow resumes. There seems to be a grinding noise. I believe that the wiper motor is the problem. I didn't see suggestions about disassembling the motor assembly to look for easy repairs for this particular problem. Please advise. Thanks
PS, on an unrelated topic, my power steering fluid leak suddenly stopped (knock on wood).

A while back, Art asked me to post my solution for I believe his database of odd wiper problems.
Maybe my several month drama will also help someone else.
The wiper motor works off an on, but only at one speed. At high speed, it seizes 1/3 of the way up, but moves when I switch to slow speed.
It turned out to be the wiper motor. I installed a junkyard wiper motor and the wipers are like new: 2 speeds; intermittent; no seizing.
Thanks, everyone!

I don't think you need to look for the relay, which is probably stuffed deep under a panel where you might rest your left foot. The relay isn't involved in high speed.
Zero voltage at 53B points to the switch, or harness wiring perhaps. See if you have anything at the stalk (green wire) when running fast speed. Let us know what you find so I can add "No High Speed" to my list of oddball symptoms here: http://cleanflametrap.com/wiper.html

I don't understand.

The "stalk" is another word for the switch you use to turn on the wipers.

I understand that the stalk means the windshield wiper lever. I don't understand what to look for and how to test it.

Snowflakes keep fallin' on my Volvo
And just like the guy whose feet are too big for his bed
Nothin' seems to fit
Those snoflakes are fallin' on my Volvo, they keep fallin'
So I just did me some talkin' to the sun
And I said I didn't like the way he got things done
Sleepin' on the job
Those snowflakes are fallin' on my Volvo, they keep fallin'

Rain-x
Never need the fast speed on the wipers, or the slow for that matter. Interval still handy.
Pretty good in snow too.

I'm a big fan of paying an extra few pesos for the Rain-X infused washer fluid ever since I owned a 850. On that model the drivers side wiper has a tendency to pull away from the windshield over time requiring modifications to keep the wiper in contact.
Once properly Rain-X'd I prefer to use the wipers as little as possible. But then I found myself constantly distracted by adjusting the interval speed of the intermittent setting. Now that I own a S40 (2005) I drive along (distractedly) marveling at the wonder that is automatic rain-sensing wipers.

Have used Rain-x before. Great stuff! I use Rain-x car wash now. Best car wash I have ever used. Not only does it help keep the windshield clear, it also gives the whole car a beautiful shine because it has some wax mixed in. Allows me to skip car waxing! However, with winter around the corner, I will compound and put a coat of wax on it...:)
