Ive been thinking of ways to get the wiper motor high speed out to the wiper arms a bit faster.

any thoughts?

Ive been focused on a way to relocate the radial pivot that drives the arms closer to the wiper motor output shaft , that would make it faster.

this is in my opinion a problem with our cars where the high setting in some rain fall cases isn't high enough.

no traction on this thread?
been doing some thinking on how to mechanically increase the speed of wiper arms,, im thinking of relocating the pivot point at the regulators but this would be a very calibrated adjustment which I don't think is possible in a garage setting,, I think the fulcrum/pivot points would need to come closer to the center to go faster??

Maybe the non intermittent wipers are faster?

I've never been worried about the speed of the wipers

I have found myself in terrible downpours of rain while moving on the highway,, you know those people that you see pulled over under an over pass when it gets real bad??? that's me.

the wipers move normal for high speed yet I wonder why the heck do other cars today have much faster wipers when put on high. that's what im after.

I remember your cars as being higher mileage. My wiped motor burned out on me while i was doing pizza delivery in a snow storm. I took the rest of the day off and hit they junkyard. When i got the "new" on off an 83 bird, it was easily twice the speed of the old one. Car was probably around 290k miles then

You could simply try wiring it directly to the battery and see if speed improves? If it does, replacing the wiring, or adding new wire and relay, will help. Voltage drop will slow down motors a good amount. Wiper motor age and electrical wiring quality will make a big difference. Think about how power windows or power seats move with the engine off, versus engine running. You get close to twice the performance from 2 more Volts, and the motors live a happier life.

I never had a problem with wiper speed, but at max, when really wet, the wipers will slam against the side of the a-pillar. My car cruises with 14.5V at the battery terminals - many grounds, and many power wires, have been replaced and improved from the factory original harnesses. I still have 1/0 gauge wiring for the main power wires and cable going to the audio amplifiers. Just soldering (if the old wires will still take the solder) and re-torquing connections can help a great deal. Using some thick conductive grease at ground bolts can also help cut down on oxidation, so your electrical system continues to function like-new. Think about what people do for maintaining their lead-acid batteries, but neglect for the rest of the vehicle - corrosion and oxidation DOES occur elsewhere.
