This moring my GLA 220 Cdi was full of snow, both on the roof and the front mirror. I turnd my windshield whipers on, and they push all the snow off. A bit later on the freeway i was doing around 120km/t and the whipers started touching, they got stuck, to make an X over the front class. I stopped the car and cleaned off all the snow, as i stopped the snow form the roof went over the front mirror to push the whipers down. Now only the whiper on the drivers side is woring, and the other one has stopped workings completly, and it was stuck i this wierd posision when i open the hood too check. Anyone here got some tips for me?
