I just replaced the windshield wipers for my car (full blade assembly, not just blades) and have just had my first need to use them. The passenger side wiper barely contacts the windshield and the driver‘s side is not much better. Long story short, the wipers don‘t contact the windshield near hard enough, when at all. How do I correct this without having to pay out the wazoo? Off hand I don‘t remember the brand, but I believe they were Bosch and I believe the problem not to be in the wiper blade and assembly replacements but that the problem was likely present before I got the car. How does one fix this problem?For what it‘s worth, these are on a 1984 Camaro Sport Coupe
