Hello, some help would be appreciated as l have a problem. In the past there was a problem with the windows not working traced to a broken wire driver door to the A pillar. This has now come back suspect another wire broken. But now also the front wipers are not working (rear wiper ok washers ok). If you sit in the car power on nothing, however if you open the drivers door and actuate the wiper stork you can hear the window relay clicking in but still no wipers. Can this all be related or is it just coincidence. Also please how do you get to the relays and where is the convenience control unit so I can check for corrosion. Thankyou friends
