Right, this problem has been going on for a while now and still havent been able to fix it. Wierd thing is that Aussie Q45a is having the exact same problem as me now too. The cars are both '89 JDM Q45s.
Now the problem is: Drivers window is not working at all, and the switches on the centre console arent operating the other windows. The passenger and rear windows work when using the switches on the doors though. Window lock button works fine.
Originally somebody did a halfassed test and told me that it was just the switch that was faulty, so i believed him and went off and got a new switch from Japan. Plugged it in to find that it still doesnt work, also tried it on AussieQ45a's car too.
Do the local control units(LCU01-B) on the door ever go bad? Or the body control module? We have 12v getting to the LCU but we aren't really too sure how to test the unit - is there an easy way? What voltages should we be seeing at the switches?
