Fuse 1 blows when ignition turned on

I've got a 400E that blows the fuse 1 when the cars ignition is turned to position 1 engine not started. Then no electric windows will work or heated seats but the seats will electrical move with the adjustments panel.
Radio dies as well.

I've tried to disconnect/pulled out the radio.
Still blows out the fuse nr. 1

Removed all the plugs from the convenience module and big yellow control boks under the rear seat left side. Still blows the fuse.

Then pulled out the combination relay for heated rear window and turn lights viper etc.
It still blows.

Then tried to remove all relays inside the relay box at the fear of the fuse boks. Then mounted 1 at the time and tried turning the key. Now it never blows. But it turns back some days later and starts to blow again.

Is there any known isues with this fuse blowing out every once in a while?
And are the fuse designation card the correct one for a 400E or are all 124 simular?

No. This is not normal, something is wrong.



Most 124 will be similar. Use the ETM schematics (link below) to trace all components connected to fuse #1.

Thanx. It showed up to be under the ash tray were the 3 pin plug were attached to another plug that had and ekstension plug to the ashtray.
But in between some wires were attached as well. So just removed it and it worked. For while at least.
Then the X30/1 gave problems. It had some korrosion that shorted sometimes.
Then I cleaned it, and it worked.
