My windshield wipers decided not to work yesterday while driving down the freeway as it downpoured. Luckily i was already at my exit. Anyway, I went to check the fuse and there's like a piece of black plastic lock on it, so i can't pull it. I checked the manual and it says to have the wiper fuse checked by a dealer.. wtf? Is there any way i can check that myself, or do I really need to go to a dealer. I tried listening for the clicking sound of the relay, but hear nothing. My rear windshield wiper works, as well as my squirters. Any insight?
