HELLO!
'I've been having this problem for three years now: the fuse for the window lifters keeps blowing at different intervals!'
Recently, the fuse has been blowing immediately.
OH YEAH, THE SAME GOES FOR THE REAR WINDOW HEATER.
When locking or unlocking, I could always open and close all the windows without any problems!
'THEN I THOUGHT, IT MUST BE A PROBLEM WITH THE WIRING!'
OF COURSE, I FIRST CHECKED THE DOOR AND THE REARVIEW MIRRORS, COMPLETELY UNWITTINGLY.
Standing in the doorway, I noticed the black, flexible cable duct, which was slightly bent in the middle.
I loosened the screws on both sides, pushed it to the side, and there I saw some white cables.
I noticed the same thing on the passenger-side door.
NEXT WEEK I WILL CHECK ALL THE DOORS AND THE TRUNK, AND I WILL INSULATE ANY EXPOSED WIRES WITH ELECTRICAL TAPE!
I will let you know if the fix works.
Best regards.
