Another slow wiper question

[knever3]

My wipers are slow and kind of jerky. I replaced the bushings when I pulled the assembly out. They are much tighter now and don't slap the cowl. They are still slow. Added a better ground and checked voltage. I have delay that works in every position. I wanted to open the motor and clean and grease it, but I thought the bolts were going to break. I don't want to spend $100 on a reman motor and have the same problem if that is the way they were designed. Does anyone have a success story they would like to share?

 

I thought about retrofitting a newer motor from a 97+ but haven't seen if that was possible. Maybe a video would help.

I had a similar problem, open it up, pull it completely apart, clean everything and put a lot of grease in all bushings and gears, it is the only way. Jhook arms help a bit too, it will never be as fast as a modern wiper system but you can make it functional. This was on a "remanufactured" motor too, they just spray paint them and call it done.

This^^.

 

what did you do for a ground improvement?

Just got done pulling the assembly back out, a few things of note.

I added a ground from the case ground to the vertical bracket bolted to the cowl from inside the engine bay with a piece of 14 AWG wire and ring terminals. I opened the gearbox up and the grease was still perfect. Decided that since I was in there I cleaned it all out and put moly grease back in. I had already put moly grease on all the linkage bushings previously. They are still about the same, although I think I fried the delay box while unplugging it while the wipers were running. They would not shut off. So now I have no delay. I measured 13.1V at the delay plug. I guess it is what it is, OLD. Now I will open the delay box up and peek in there at some point. I remember someone has done this before but can't remember the outcome.

Where is the delay box located, I would love to get that working again. Interested in what you find out.

Delay box is under the driver side dash, it's kind of flat with connections on two sides and is Velcroed into place.

You might have moved the little fingers in the gear box that tell the delay module that it completed a cycle. Did you pull rotor out of the motor and clean and grease those bushings? 

[knever3]

I didn't pull the rotor out, however I did pull the cover and repack the grease so the pins may have gotten moved. I'll revisit when I get a chance. The wipers don't return when I shut them off, but I think it gets confused going through the delay setting on the stalk.

I had that issue with the wipers just being on-off with no return to home. For me it was the fingers in the gearbox (attached to the cover), make sure they make contact with the electrical contact points on the big gear and put a little silicone grease there to keep them clean.
