this is a normal recurring problem. it's like the problem u hv with yr wheel alignment with yr dad's car. got a balancing service then after 2 months the car still swerves to the right while u let yr hands of the steering to makan yr nasi bungkus like i always do. ;)
ive changed my wiper countless time. cheap "cap long" ones, expensive silicones and even affordable "cap ayam type R" wipers. (btw, type R wiper blades for a kancil? hehe these guys are so creative and over-ambitious :D ).
my advise, dont park under the sun, keep the windscreen clean. if u cant do tht, make friends with the taukey coz u'll soon be his regular customer hehe.
