I disconnected the batery on my 01 e430 and now the window auto up/down does not work on 3 of the windows. I Read about resyncronizing the windows on an old post. there were no details on this, can anyone elaberate on this?
to resync all the windows one by one hold all the buttons in the up position for 10 seconds after all the windows have shut (meaning that at one time all are being held in the up position).
Worst case if that doesn't work, bring them all down (by pressing the switch half way), and then bring then bring them all up as mentioned above.
Here is a comprehensive list of all items that need (or may need) to be synchronized after loss of power (i.e., battery disconnect):
Synchronizing Head Restraints:
If the power supply was interrupted (battery
disconnected or empty), the head restraints are no
longer adjusted automatically. To resynchronize the adjustment feature, turn electronic key in steering lock to position 2, move the seat completely forward and the head restraint fully down, and hold respective buttons for approximately two seconds.
Synchronizing power windows:
If the power supply was interrupted (battery
disconnected or low), the windows cannot be opened or
closed by the Express feature. To resynchronize the express feature, press side of power window switch to resistance point until the window is completely closed and hold for additional 2 seconds. Repeat procedure for each window. The automatic full opening and closing procedure of the windows should now be restored.
Synchronizing sliding/pop-up roof:
If the power supply was interrupted (battery
disconnected or low), or if the sliding/pop-up roof is blocked during closing/opening procedure, the system has to be synchronized. To do so, turn electronic key in steering lock to position 2, move and hold switch in direction (3), until the sliding/pop-up roof is completely raised at rear, and
hold for additional 1 second.
Synchronizing ESP:
If the power supply was interrupted (battery
disconnected or empty), the BAS/ESP malfunction
indicator lamp may be illuminated with the engine
running. Turn steering wheel completely to the left and then to the right. The BAS/ESP malfunction indicator lamp should go out.
Synchronizing remote control:
The remote control may have to be resynchronized, if
the vehicle cannot be locked or unlocked. To synchronize insert electronic key in steering lock.
The remote control should once again be operational.
