My right windshield wiper will only feebly produce spastic motion now - not sure why. It does attempt to function though. I checked at the base of the wiper arm, and the black nut was loose so I tightened it down only handtight to see if that would make it operate normally - no handtools at this time. It is raining quite a bit in North Carolina today... Having two functioning windshield wipers would be sort of nice. Luckily, my driver-side wiper is still working fine. Does anyone have any words of advice on this problem? I'll be at work the rest of the evening, and I hope to repair the problem on my off days this weekend. Thanks in advance for any help you folks can give me.
