1985 W123 300CDT Electrical Short - Windows blowing #2 Fuse

[kalikar85]

I just bought this 300CD and spent the last few weeks doing all the recommended service and maintenance myself to get it in good shape.

Im nearing the end of my restoration and have a problem with an electrical short.

When the car is on and I'm operating the windows fuse #2 blows. This causes not only the devices listed on fuse #2 to not receive power but it causes the windows and hazards to stop working also.

I had the radio, antenna, clock, visor mirrors, all out at one point and this problem persisted. I also replaced the drivers door switch.

Why are the windows affecting an unrelated circuit (they are on fuse a and b)? Similarly, why is fuse #2 causing the separate window circuits to lose power, once they cause it to blow?

Could I have a frayed window motor wire in the door post? Im duped.
