With my wiper control relay plugged in, my windshield wipers refuse to turn off once the key is turned to the on position. With the relay unplugged, the wipers work perfectly. What the hell is going on???

Very perplexing windshield wiper issue, relay related

Hey Adam, can you tell me if the wipers are stuck in the high of low position when on, and relay installed? Also with the relay removed only the high and low function correctly but intermittent, and wash do not function correct?
Also, do you have a multi meter that can measure continuity?

You might have gone to bed already, if you have then here is some stuff you can check when you get back on.
Check for continuity between pins 1 and 2. If there is no continuity then the relay is bad
Next check for an open between pins 2 and 5. If there is continuity between those two pins then the relay is bad.
Give those a test and get back to me.

It's stuck in low with the relay installed. With the relay removed only the high and low function. I don't have the sprayer system anymore (99% removed). Yes I do have a multi-meter, but I don't what settings to put it on to use it (I wish I was kidding).

What settings do I set my multi-meter to and how do I know if I have continuity?
Your multimeter should have a setting that looks like the above image. While this setting is correctly used to check diodes it works great for testing continuity. If it beeps you have continuity, if it's silent then you have an open.
I'm willing to bet you will have continuity between pins 2 and 5. In which case your relay is bad.
You moved back to Cali?

Yeah I'm back down here, but I'll be up for PACNWN.
Got the basic model, but that's no problem. Turn it to the 200 next to the horseshoe symbol. now take the test leads and touch them together. It should read between 0.1 and 1.0 depending on how precise the meter is. This is to verify that it is working properly. Now separate the leads, whatever is now displayed is how your multimeter shows an open (different mulitmeters display this differently). Ok, now go ahead and preform the tests I mentioned above. You already know what an open looks like and for continuity, it should be between 0.1 and 4.0 more than 4.0 and the relay should be replaced. These are my numbers from what a standard relay will show and not necessarily the ones Toyota specifically lists, I don't have those. Actually 4 ohms is a little high but I have seen them still function as high as that.

When I touch the leads together, I get a reading of 004. When the leads are apart I get a reading of 1. When I touch the leads to pins 1 and 2 on the relay I get a reading of 004. When I tough the leads to pins 2 and 5 I get a reading of 1
Even when the lead are separated, not touching anything? Your multimeter is supposed to display a -1 when not touching anything. Without it working right the readings are hard to correctly understand.
Ok, for the time were going to assume, i hate assuming, that the ( - ) is not showing up. I base this on the fact that the pin 2 to 5 reading would be incorrect if it showed anything below the reading given when the two test leads were directly touched together. So well say the reading on pin 2 to 5 is indicating and open, which indicates that the relay portion of that module is functioning properly. So we move down the line. Next we check the connector.
Place one lead in pin 8 and the other lead in chassis ground (pin 7)
Now with the wiper lever in the off position it should indicate an open ( 1 ). Next move the wiper lever to the "Intermittent" position. At which point it should indicate 008 or less.

The first part of the test did as you said it should, giving me a reading of (1). The 2nd part of the test failed, giving me a reading of 083
Well the second part of the test failing isn't a big deal as that won't cause the problems you're describing. If the first part had failed we would have had some answers.
Ok bud, last test
Check for continuity between pin 5 and pin 7 if you get any reading other than an open ( 1 ) the relay is bad.
