When is the worst time to lose a windshield wiper?  How about on Tuesday during that crazy storm when conditions were close to white out and you couldn't see anything even with the wipers.  That's when one of my wiper blades became unhinged and ineffective.  Fabulous timing.  Luckily I was close to my destination and once I arrived I was able to get the blade back in place and my wipers worked fine.  So, what do you do if you're on the highway and suddenly your wipers fail and there is no where to stop, or no way to easily repair them.  This is what you do, if you have a passenger.
