Windwhield Wipers

[Stomis]

Ok so I finally did my motor. Got my intermitency back okay awesome. So I realise I hooked the linkage 180* of what it was suppose to be. *Sigh* take it apart and fix it. Everything is back together so I start testing them out. And slowly and slowly they are getting very very slow.

I'm like no way I got a bad motor. So I feel the motor and realise I forgot to hook up the ground to the case of the motor. Do that and let it cool off. But now my blades are stumbling really bad coming down. Any ideas?

is the glass dry?

 

[Stomis]

Yeah I no this seems a little simplistic. I thought the stuttering could have been from the glass being dry but I'm starting to think its cause I got those super conforming windshield wipers and they had this weird like lubricant on the blades and smart me wiped all of it off.

Can't be much help, these wiper systems aren't that great at this age it seems like. Stuttering, slow, intermittent periods of non-stop running, you name it.

Only thing I can think of is to make sure all the connections are good, and that the pivot points are lubed up. Maybe remove the blades and disconnect the mechanism from the motor and see if it's hard to operate.

Hijack, is there anyway to adjust how close the blades are to the windsheild? for mine it seems theress to much pressure on the wiper blades.

 

[dyeager535]

Not that I'm aware of. Pressure on the windshield is due to the spring on the underside of the wiper arm, but I can see aftermarket complete blade replacements having taller "frames" that may contribute to additional pressure. Which is why I don't believe in using anything other than the replacement wiper blade itself. Of course, if the blade itself is taller than stock, could do about the same thing.

The general windshield wiper specification is :: 1 ounce pressure per 1 inch of wiper blade. So a 12 inch wiper blade should exert 12 ounces of weight (pressure) on the windshield. A guage used to weigh fish can be rigged up to check the pressure of the blade against the windshield. Allow the wiper to travel half way up the windshield. Turn off the power. Hook the guage to where the wiper and arm connect . Carefully pull the guage until the blade completely leaves the glass. Record the weight in ounces ( oz. ). Divide the length ( in inches ) of the blade into the recorded weight of pull. This is your ounces / inch. If you are too light carefully bend the arm to make the spring exerts more pressure on the blade ( and glass ). Recheck pressure.
To insure accuracy standardise the fish guage by suspending a known 1 pound weight and checking the scale 1 pound = 16 ounces.

You could change the blade length if you are too heavy then it sounds like. These things are pretty tolerant of different length blades, I think you can fit/use at least three different lengths.
