Hi all,

I'm about to lose my mind. I have a new OE-Style AAW harness under the hood and new OE-Style AAW under dash harness. It's very nice and complete. Kudos to AAW on the quality.

However, my wipers never worked and so I belief is that the motor was dead. So I purchased a new wiper motor from New Port Wipers and it went right in - no issues.

They include a new switch and wiring from the motor. The red wire is to go to a 10-amp fused circuit. Well, looking at the diagram, it appeared that I'd be able to use stock Yellow wire that leaves from the fuse block to the wiper motor - so that's where I connected the red power wire. Go to fire it up and no go. So out come the multimeter and I find that I have no power on either side of the fuse labeled "Wiper" on the block. Tried it ignition on and off.

I can't figure it out. Am I crazy? That should be hot there, right? In stock config, it provides voltage, runs thru the motor and the switch controls the ground (The New Port just takes a 12v to the switch and the switch applies voltage - there is a ground wire on the motor like the stock one).

Any ideas?

Thanks,

--Jon

To add to this, when I pull on the parking lights, the left blinker light comes on? Also, when I pull on for the headlights, the front parking lights go out - I seem to recall them staying on when the headlights were on.

Weird. I should have mentioned that the under hood kit was there - things like the blinker light with the parking light didn't happen before the fuse block/Dash kit change.

Parking lights will go off on the early cars when the headlights come on. The indicator light being on when the lights are on sounds like a backfeed ground on the affected parking lamp. You should have voltage on both sides of the wiper fuse when the key is "on".

Thanks Donny. I'll check the wiring on that light.


I don't have voltage on that wiper fuse or the fuse below it - looking at the old harness it looks like their primary side is bussed together - any suggestions on where I'd look to see why it's not getting 12v?

Yes, disconnect the battery, take the two screws out of the firewall and see if the wire that plugs onto the bussbar has pulled off the bussbar.

HI Don,

Finally got around to looking at it and sure enough - no wire connected to it, but I don't see any loose wire that would be the one to connect to it? Here's pic and looking at the diagram, I don't see that there is a lead to it.

Please post a picture of the front of the box and where you are checking for voltage.

Thanks, Donny

I'm checking on both sides of the fuse labeled "wiper". I went and checked my OE block and it looks the same and looks like nothing was/is connected to that tab.

Nothing that comes thru the front appear to be what provides the 12v to the wiper. My lights works, car starts, etc.

Looking the wiring diagram - should this be getting switched power from the Tan/White off the ignition? Seems like the tan wire then might feed 12v to the tan wire on the block that feeds the wiper and the one below?

So, perhaps the problem is at the ignition switch is where I think I should look next?
