Non-E30 tech question: '91 Nissan pickup

[Jand3rson]

I have a '91 Nissan pickup, and yesterday, the windshield wipers quit working. When I turn them on, the arms still lift up and down slightly, but only about a 1/4", and the blades don't move at all. It's like the motor doesn't have enough power to move them. If I manually move the arm by giving it a little nudge on the upstroke, the arm will move across the windshield, but won't come back down. And when I do this, the other arm doesn't do anything at all. Anyone have any idea what might be going on?

sounds like your motor is going. Is it making any noise like the gears being stripped? Are the arms screwed down seculrly?

[SpecM]

yea, do they (each arm) move together or indapendantly?

Wiper Motor. 28815-01G00 - $178.84 cost. $296.90 list.

The arms would move together, as there is only one wiper motor on the truck.

Upon closer inspection of the arms, I can see the little spindles that turn the arm turning back and forth inside where they mount to the arm. It seems like they aren't gripping the inside of the arm base to turn it.

this happened to a landrover my dad had, the spindle inside the arm stripped out to we drilled a hole horizontally through the wiper arm and spindle and then put a bolt through it, it worked very well and it was basically invisible.

Joshie: you need new wiper arms, I see it happen all the time

^^ What he said, or you can cotter it and screw the output shafts up forever, or junkyard some new arms.

Let me guess, turned the windshield wipers on to clear a bunch of snow off? Bad, bad idea. The weight from the snow stops the arms from moving and the motor keeps turning resulting in stripped splines.

Pull one off and check to see if the splines are stripped on the arm or on the shaft. Hopefully they are just stripped on the arm.

luckily, most of the time it is just the arm that strips. so much easer/cheaper to replace just the arm!

Stripped. If you really don't care. Tack weld the arm to the spindle.
