Hi All, I'm really struggling in diagnosing an issue with my front wipers and i'm hoping someone can shed some light on it... Vehicle: AUDI A3 54 plate Scenario: I bought the vehicle around 18 months ago and the concerned was in working order. The vehicle came with cheap aftermarket HID's which i have been meaning to change for some time now (some random Chinese make, i'm not sure which) Obviously at the time i wasn't aware of the potential issue (until trawling helpful forums like these) that can occur with HID's and wiper motor/wiper control module failing, from what i can ascertain that issue is due to either high voltage/current causing damaging Electro-magnetic charges, or the fact that the headlights and wiper unit share the same earth, high voltage causing damage to circuitry??? Anyway, they are still fitted and i assumed this to be the cause of the failure. Also, i have tried the obvious, fuses are fine and the bonnet latch is in good working order, so managed to borrow a working wiper motor from a friend, still not working not even a flicker when ignition on as they do. Now am i to understand that due to the direct power feed to the motor, there is no relay in the circuit that gives an audible 'click' upon using the stalk on the column? this leads me to believe that it could be the wiper control module under the dash? of which i have no way of telling if is working or not, can anybody provide information on what values, resistances etc it should read on particular pins? or another method of testing perhaps? If anybody has experienced this or something similar, your thoughts on what to do next would be greatly appreciated - RainEx only works for so long! haha Regards, Oliver
