Thank you Pontiac 🙂
- I just got home from school, will start working on it soon

Hacon, look at this and see if it helps. It is what I was referring to.

I'm confused, I thought park relay was only for the wipers being able to shut of momentaraly and "park" all the way down on that chrome plate on the windshield... :/ hmmm,. Does this mean my park-spring could still be bad? I was sure that park only meant that the wipers one way or the other was able to hit the chrome plate and stay there even if just for a few secs... 😛
Thanks

Edit: My wipers only delay if I restart the key, then delay works for a minute at most a couple minutes.

Yes "park" is when the wipers drop down under the cowl and shut off for good. The relay keeps the motor energized until they are all the way down and then a mechanical switch shuts the motor off. "Pulse" or "Delay" is when they stop in the down position but do not drop under the cowl, then they restart depending on what position the delay switch is in. It is actually a rheostat that varies the voltage to the pulse relay. If your delay works, but motor does not shut off, then the wiring or switch is suspect.

Well, run those tests and see what you find. Disconnect all the harnesses and test for shorts to ground. And find out what that blue wire is for.

Oh... well, then i've got more news... My wipers do the exact same thing. When they used to park before wipers got bad they sat in the exact same place as they do when I hit the Delay middle position... They park all the way (almost) on the chrome plate, one of the wipers rides just a tad over the chrome plate, see the pic...

I will do that, just waiting for a hand from my dad who has a little bit more experience with wiring (not in cars though) 🙂

 

[Bonnewagon]

Hmmmm, you may have a worn linkage or your park pawl does not pull them all the way down. It's not all that important unless because of that the switch that shuts off the wiper motor is not engaging. You can bench test the whole assembly but that means removing it from the car and hooking up jumper wires. I would rather test it on the car. By the way, you can make a simple 12 volt tester by soldering some wires to a 12 volt light bulb and leaving about an inch of soldered bare wire on the ends as probes. And, NICE CAR!!!!!!

Yeah taking the whole assembly off sounds like a hassle.. I have a multi-meter 12 volt tester if that's what its called, but a great idea though!
Thanks 🙂
