Volkswagen Passat B5: Comfort Module Fuse Burnout - Seeking Experiences with 1JO 959 799 AH

Hello, At the beginning I would like to point out that I did not find my problem on the forum. Namely, I have a problem with the comfort module when I was driving, the fuse burned and it must have happened while driving. the comfort module does a short circuit after connecting the plug with the power supply. when I disconnect the module and insert the fuse I have 12V power supply. The module itself I checked and I could not see anything more comforting, I also checked on 2 other modules but with the same numbers and after connecting I immediately blown the fuse. Everywhere around a dry bunch of wires looks ok the same weight. module number 1JO 959 799 AH. Has anyone had a similar problem?

As you disconnect the main power from the module, you do not have power on individual circuits that can cause a short circuit. Many things can be, the windshield wipers can stand, the window lifters, or the beam in the door closes to the weight of the car. More details, what number of fuse, which car?

When I had a connected module and this fuse was blown, the windows, the rearview mirror and the central remote control did not work. The car is passat b5 1999. combo. the fuse number is 14

as far as I remember, you have connectors in every door, with this harmonica. Unplug and check if there is a short circuit. In such cases, I put the H4 bulb on the wires instead of the fuse (depending on the fuse inserted)

Today, I undressed the door and the flap from the trunk and all the cables I removed and it was the same, but after unbuckling the cubes that are downstairs in the driver's seat and the problem stopped but nothing else worked, this is the blue cube on the right. does anyone have a schematic where these wires can go?

did you undress the door and disconnect the cubes eg from the windshield motor, lock? in this way, you have not eliminated the short-circuits in the harmonica. You have to unplug the main plugs to the door. you will see them as you take off the harmonica or plastic in the front pillar

so I unbutton all plugs in the door and there are some other cubes anyway? are these shown in the picture?

No, you have a plug for every door. Enter in Google and see how the door beam looks like.

when I desired with a bunch of wires, I came to the same cubes only on the passenger side

F14 (10A) is the power supply only to the comfort module in the floor, remove the left threshold cover and check the beam in the left threshold to the module itself, because there is probably a short circuit, red / blue cable from the box to the cube on the post, then red / white to the module itself .

problem solved, it turned out that the short circuit makes me a lamp that is in the middle and now everything is ok, but thank you for your help. the topic can be closed
