HELLLPPPP !!!! Audi A4 2003 Wipers don't work because an electrical fault !!! Hello everybody !!!! I have a problem with my wife's car: audi a4 (b6) 2003 1.9 tdi 130 hp, RHD Last week after a very heavy rain in London, my wife told me some water leaked inside the car around the acceleration pedal area. When she put the ignition on next day she heard a strange noise like an electrical short and the wipers started working fast without any command :D ....she couldn't stop them...then they stopped on their own and then wouldn't start on command. Now they seem not to be working at all, they start randomly working without comand and then stop. I am trying to identify the issue I read almost all forums about this problem, and am sure that: 1.the linkage is not seized, it's moving free and working very fast. 2. the switch is probably functional because the windscreen washer and the bord computer are working 3. I read about some wiper relay no 377....but on my model i don't have this relay .i looked all over the car to find it ... 4. the wiper motor i think is ok because i checked another 2 and none is working...so i measured the connector that supplies the wiper motor and I have a live 12v in pin nr 2 and that's it and some one told i must have life in 3 pins . So my local garages told me: Ecu is dead because of water lick but i check the ecu compartment and everything is dry and clean there,Ccu is dead and need recoded for audi...and audi specialist told can be some relays located in back of steering wheel.... After diagnosis with a bosch software was found it 15 errors ...but the most important was : can't communicate with Conventional Control Unit...wiper motor stage 1... control unit...wiper motor stage 2 ... Some errors wasn't true...but was erased. Anyone have some ideas about how to fix this problem without spending thousands ?

WHAT IS THE PROBLEM EXACTLY?WIPERS DONT WORK?IS THE HOOD CLOSED???NEED MORE INFO TO HELP

Check both ends of battery's earth lead.
Remove, clean all surfaces with emery/sand paper, replace and seal with grease or vasaline.
If this is not the fault - it worth doing and eliminates something.
Hope this helps.

How to change a wiper assembly & repair wiper mechanism on 1999 Audi A4

First time you must diagnose why windscreen wipers going slow and/or stopping.
In order to find out the cause of wipers stopping you can try follows:
1. Carefully extract the wiper arms from their axles (two pieces). In some cases you need to use an extracting tool. Heed of the windscreen !!!
2. Disassemble the plastic covers from the bottom of the windscreen.
3. With the bonnet up you can start the engine, (transmission in "N" or "P" position and parking brake on). Now you must switch on the control lever of the wipers, and go to the engine compartment. If the wiper motor runs let the wiper motor running for a few minutes and switch off. Go to the step 4. If the wiper motor do not runs you must check first the electrical feeding of the motor. It is necessary to unscrew three bolts of the mechanism and disconnect the electrical coupling (difficult assurance). If the electrical feeding is OK you must replace the motor - steps 5, 6, 7. If not you must check electrical connections, the control switch of wipers and electric cables.
4. Now you must check the two bearings of wiper mechanism with your hand. In the most cases the left bearing is out of order (is very hot). This is the most encountered fault of the wipers running at Audi.
5. For have enough space to manipulation the wiper motor together with their mechanism you must extract the plastic cover of the engine computer box, and extract also the box screws. Then you can move slowly the engine computer box, just for a few milimeters.
6. You must disconnect the electrical coupling of the motor (difficult assurance), unscrew three bolts of the mechanism and extract together with the motor. You must move them slowly between windscreen and engine computer box until the wiper motor go out together with the mechanism. This is the most difficult operation!
7. Now you can repair the bearings, replace entire wiper mechanism or replace the wiper motor. It is not very simply, but it works.
Heed of the windscreen !!!
Refit all in reverse order.

Please do rate my response. Thanks!

The problem is in the wiper switch assembly itself.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Relay fault. Simply replace and all will be restored :o)
