help, am i destined to never have a rear wiper

[gyoung]

I have gone through 5 rear wiper motors, remans and new, in the last year. power to the motor. we inatalled a brand new about 2 weeks ago at the auto parts store, getting real good at it, and the brand new just growled till you nudged the wiper arm. imediately swapped it with a remanufactured and it worked fine. i tried it on and off for a couple days. last week it rained and no wiper. it is getting a bit perplexig. any ideas? thanks.

I doubt all those motors are bad. Check the power line and ground wire for voltage when the motor "fails" the next time. Also check the linkage to see if there's something binding up.
