Before you say it yourself, yes im an idiot for how this happened. The drivers side windshield wiper arm is not giving any pressure towards the windshield anymore this was because we were kidding around and someone ended up pulling the whole thing down. it is a 1987 chevrolet celebrity. motor and everything else works fine im just getting no pressure on the window so its not making full contact.what can I do myself? please dont say see a mechanic because that is a last resort for me.im looking for help here :)thanks!
The pressure on the blade is derived from an over center spring under the arm attached to stops at either end. The works of the spring is to either hold the arm way up off the glass for wiper service, or to apply pressure to the scraper blade allowing it to roll over according to the direction of travel. If the spring has become stretched beyond it's working range, it will appear normal and Must be replaced as an assembly. If it is missing same fix. But if it is there and not mounted, you might be able to reattach it. Caution as you can get cut trying to fix it.
Yes you might be able to buy replacement wiper arms from auto parts stores but these are sometimes repro and not the same as the originals so you would have to change both of them otherwise it will look weird, or you could try a few salvage yards just grab the arm you need it shouldn't cost much and there should be plenty of those models around, also on older cars there is usually a spring on the arm that keeps it on the windscreen maybe you lost or broke this spring? hope this helps.
