Alles anzeigenHello, I suspect your power window control unit is defective because your power
windows are no longer working. A defective power window control unit can also
drain the battery. The control unit is the double relay in the additional relay carrier
under the dashboard. You can't miss it, as this is the only "relay" that is twice as
wide. Just pull it off and see if the battery is empty again after one night.
Alternatively, you can also remove the corresponding fuse in the fuse holder and
use a measuring device to measure the quiescent current that goes out of the battery.
Sincerely, Chris
Thank you Chris so much. So I need to pull this control unit that looks like mp3 player or something, under the dashboard, over the day?
