Loose driver's side wiper arm - Skoda Octavia 2003
I’ve had a front wiper problem for weeks, on the driver side. At normal speed or single-wipe mode, when the car is stationary or moving very slowly, the driver side wiper doesn’t travel far enough and leaves about 15–20 cm uncleared on the far left side of the windshield. If I set the wipers to maximum speed while stationary, it reaches the full area. But when driving faster than around 40 km/h, especially on normal or max speed, the wiper sometimes travels too far left, goes slightly off the windshield, and in some cases gets stuck over the edge.
I also noticed that while turning right, the wiper reaches a bit less, but while turning left, it tends to go too far and can leave the windshield.
When the wipers are off, if I physically grab the driver side wiper arm, it feels loose from the base and can move around 30 cm in the direction it normally wipes. Does this sound like I just have to replace arm itself or the whole mechanism?
