Hello,

I've just upgraded my OEM Discharge bulbs on my IS250. Before installing them, I disconnected the negative connector on the battery. After connecting the battery back up, Everything seems OK so far except I am having problems with my electric windows. For some weired reason I cannot control the other windows from the drivers side control, it only works with the independent controls on each door.

Can anyone please tell me how the window controls get effected when disconnecting the battery.

Many thanks

 

Try a random combination of holding the buttons in the up position. Hold the driver's side in the up position beyond the detent for 3seconds+ and so on with the three other buttons. All in the up position beyond the detent click. It probably just lost normalization. give that a shot, if not then sorry..I tried.

 

go to each door and roll the windows all the way down and back up. that should do it.

 

ummm search here there are instructions on how to reinitialize the windows. look in the owner manual its in there.

 

thanks for all your help. it worked. i went through one window at a time and rolled it all the way down and then back up (once it came all the way back up, I held it for around 3 seconds until i heard a click noise and the window control led stopped flashing)
