tech NEEDED....STILL no wipers!

[SwitchBlade327]

the 60 poncho's wiring saga continues....

pretty much got the whole car wired up now, but I can't figure out how the hell the wipers wire up. The actual wiper switch is broken, so I'm just tryin' to rig up one speed on a toggle so I can at least have that much when it rains more than rainX can handle.
I have 3 wires coming into the engine compartment from what looks to be the wiper motor, their color matches the factory wiring diagram I found, and it's showing that brown=fuse panel, white=switch, violet=switch. I've been trying to just get power (using the bettery post) to it just to see if they're working, but I'm not getting anything. Am I doing something wrong or is the motor fried?

[SwitchBlade327]

anyone? anything? I can't move on until I get this wiper thing figured out, all that's left to do is the stereo system and I have to start putting the interior back in to do it.....help...

The brown wire should be hot for park to work. Power applied to either one of the other wires should make the motor work at one speed or another. That is assuming you have the motor case grounded.

[SwitchBlade327]

I'm kinda assuming the motor is grounded inside the cowl since theres no wire for it. so, if i stick one of the other wires to power it should work then right? just for whatever speed that wire may be? like I said, the wiper switch busted, and I'm just tryin' to have some kinda wipers here....

If you have power to the proper wire, test the lead at the MOTOR end.. basically pull the plug on the motor and put your tester on it. If you have power going to the motor, and nothing is happening.. I would say the motor is no good. It's not the most likely scenario.. maybe it's just stuck? Could be you have power going to it, but if it's siezed.. just a couple ideas. Just be 100% sure you have power going to the motor.

Try to eliminate everything in between the power source and the motor, then you can tell for sure.

how would I need to free it up? Just give the arms a few tugs to pull on it, or would I need to sctually remove the motor? I don't even see how to get to the damn thing, all I can see is the wire plug on the outside of it, everything apears to have a nice coat of undercoating on it, which makes identify or removing bolts/screws a pain in the ass.

[Petejoe]

The only way to free it up would be to try moving the linkage to the wipers or if they are unaccessible, you will have to remove the whole assy. Rain X may be the only quick solution http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

Hmm.. so removal is not really an option.. check for power first before you start ripping stuff apart for no reason.

.. could be that little switch you are using is no good? Eliminate that as an option if you can.

You could try moving the wiper arms.. if they move freely, than the motor is probably not stuck. That's kind of a long shot anyway, but you never know. Have they ever worked for you?

[SwitchBlade327]

ok, I tore into the thing, pulled the plug off, cleaned up the terminals, folowed the wires to the round part of the motor, popped the top off of it, exposing some kinda electromagnet looking stuff. Then i hooked plug the wires back up and touched them to the battery one at a time while I poked my multimeter around in the cap where most of the wiring goes. everything in the cap was reading full power, but nothing inside the part the cap goes on read anything. The ground looked like it went to the side of the cap, which would ground to the rest of the motor when you bolt it on right? the cap's prety crusty so i guess I can try cleaning it up to see if it's a grounding problem...I've never opened up one of these before so I have no idea what to call the parts I'm describing. The piece that sticks into the center of the cap from the motor spun easily, so I guess that's good?

[SwitchBlade327]

fuck it. now i can't get the cap back on right cos i dunno how all the little springs and shit in it were arranged before I took it off.....2 springs popped out and there two little magnet looking pieces hanging from some wire in there....I know the shit ain't ever gonna work if that shit don't get put the right place. I'm so sick of wiring.....

[IntrstlarOvrdrve]

Hmm, I really dunno but you could tie your shoestring to them and pull em like I've done once or twice http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif Or just coat the windshield in Rain-x which I have also done once or twice. Sorry I can be of any real help http://www.jalopyjournal.com/ubbthreads/images/graemlins/blush.gif

What you have there hanging loose are the brushes for the motor. The springs are designed to push the two brushes against the armature. The springs should have a place to seat in there and the brushes will fir against the (shaft)armature. You may not be able to install them with the cap off. You may have to remove the motor to get to it right to install them. Check the ends of these blocks (brushes) and see how much wear there is. If they are too wore it may be time to replace them.

Hope it makes you feel better to know in your frustration you're learning a lfetime of experiences doing this. Then maybe some day you can help a young punk along..who knows maybe your son. http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

Heres how the brushes look like in this motor.

If I remember right the wiper switch is just a ground to complete the circuit. You should have power at the wiper with the ignition switch in the run position. Try grounding each of your loose switch wires one at a time ( after checking for juice!). One thing is for sure. I've seen lots of wiper malfunctions and almost all were the result of poor grounds. One of the wiper motor mounting bolts should pass through a heavy copper strap. Try running a separate ground through another bolt to the body. Most wiper motors are mounted in rubber insulators so the ground strap is crucial to making it go. The only common motor malfunction I seen is when the wipers won't park. On older cars that is usually bad contacts within the motor. Good luck. Bob
