I have a 96 a4 2.8, I used to be able to lock all locks and roll up my windows by turning the key in the driverside and passenger side keyholes now it will only work on my pass side. The worst part is my aftermarket alarm is connected to my driverside lock so the alarm will arm but not lock and unlock my doors as its supposed to. Does anyone have any ideas at all as to what the problem could be? I found a left door lock computer control module on ebay if that could be the prob but i dont want to buy it if i dont need it. Thanks again for saving me time and money as always!
