Relays and Such, Troubleshooting Wiper Assembly Options

[MiniStevieG]

Any idea what these 2 might be? Found the first one tucked up under my dash
The other appears to be a female end missing the relay which I suspect may be related to the wiper assembly which is rusted frozen and will need to be replaced anyway. Going to start another thread seeking advice for how best to remove the old wiper assembly. Not sure though.

Not sure which relay the first one is. There are several on the fuse panel (have to drop the fuse panel in order to see them). Drops the fuse panel (two screws) and see what’s missing a relay.

The second MAY be the block for the intermittent wipers. The intermittent wipers were an option that not all cars had. The absence of a relay there wouldn’t affect the operation of the wipers, just the intermittent function.

I don’t recall the block having 9 spots, though. Should be easy enough to check the 914 wiring diagram for you year and track it down based on the color of the wires, can’t see them (or actual numbers of wires) in this pic.

The wipers are a long job to get to. Gas tank comes out, then the fresh air box. Then you can pull the windshield wiper assembly. There is a small rubber isolator that attaches from the wiper frame to the firewall. Some people miss that and break it when removing the assembly. It’s probably dried out and needs to be replaced anyways. 914Rubber has them.

The usual culprit to slow or non-running wipers is that the shafts seize up inside the tube that they pass through in the assembly frame. If they’ve never been serviced that grease is minimum 43 years old. Clean all the old grease out, regrease and reassemble. If you’re really ambitious the wiper motor itself has a small gear set in it. Pull the triangular shaped cover and clean and regrease that as well.

BTW I see you’re in Dallas. I think Zim’s is having a 914 get together in April.
