Recently my passenger windshield wiper stopped working. When it was snowy/icey I didn't let my windows fully defrost and tried using the wiper blades being in a rush to get going to work and I think something broke. The drive side works fine but the passenger won't go up or move at all. It went for a bit of kind've half moving but not it doesn't move at all.
Yesterday I tried to see if a bolt was loose or something and noticed when my car is turned off if I try to move the drive windshield wiper up it's pretty locked in place but the passenger one was loose and I could move it freely up and down which told me something is broke.
My question is how do I fix this? Do I need to buy a whole need wiper or what can I do. Any help would be appreciated and links to how to fix it if I can or links to where I can buy a new one and how easy is it to install. Thank you, just would like this fixed kind've a pain when it's raining now and I only have one wiper, not to mention looking like a idiot .
