Ive had a real nightmare with my rear wiper on my A3, firstly when i purchased the car around 2 months ago i tried the rear washer jet when i got home and the water just runs from the inner boot lining which i heard is a common fault? so Ive avoided pressing the rear washer, Then i tryed the rear wiper and it came on and stopped in the middle of the screen so i give it a nudge and it worked ok and has been doing so for the passed few weeks,
Then the other day i switched the rear wiper one and it stopped in the middle of the screen again so i got out to give it a nudge and it was stopped dead and wouldn't move, i opened the boot and there was a horrible smell burning like if the motor has burnt out, i check all the fuses and there all ok, so i then decided to remove the boot lining to investigate, when i got the plastic trim off i removed the alu cover from the wiper motor and the mechanism was full of a horrid brown gunk and it was all corroded and rusty, I cleaned the mechanism and tried the rear wiper again but it does not work at all is this a common thing ? also theres a small PCB module (computer) the the left of the wiper motor what is this ? it seemed like the burnt smell was coming from there? Help please!
