help wiper issue

[everell]

hi chaps

i have a 06 1.9 tdi classic and the wipers stopped working in any mode except when i ask to wash the screen, then for some unkown reason the wipers would come on when driving when it was sunny??

took it to my garage and they said it was the switch and fitted a new stalk / switch , this worked for one day then whn back to its not working or sporadic stop starting so it went back the next day

they di tested the car and said it showed a faulty switch , so another new switch was fitted came home ,all working got into the car the next day and the wipers do not work and come on sporadically again

anyone have any idea what the issue may be its costing me each time!!! my other octi 4x4 is fine??

Help car still not fixed and the issue is worse

The wipers will not work then at a random point the will just come on and will wipe at various intervals not selected on the stalk

The garage has changed the stalk twice saying the original one was faulty then the day I picked it up the new one did the same but worse so the changed it again for another new stalk

It's been at the garage since and is showing no diagnostic faults and all the relays are fine

They are now saying it's the motor and a future 300 - 400 pounds to fix??? If the motors gone then why do the wipers work at all?? And even when the car is switched off and locked??

Anyone with any ideas ?? Cheers going mental now!!!
