Rear Windows only operate from rear switches

[dsp123]

Hi guys I am new to the forum and have a big issue with my 84 300D Turbo. What going on is that I can roll down my rear windows using my rear switches and I can roll down my front windows using my front switches, however when I try to roll down either rear window using the front switch my fuse blows for that window.

To date I have done the following- replaced the relay, replaced the master driver switch with an old one (not sure if it works), removed the door panels and verified that the two wires at each window that should have 12.6v indeed do. I have pulled out the carpet and traced all wires looking for a short. I have even jumpered each window right to the switches. All that and no change.

I am becoming very desperate and have even ordered a new master switch and expect it to arrive later in the week. Any help or ideas is greatly appreciated.

This sounds crazy but maybe someone installed fuses which are below the recommended amps. In the SD the lid to the fuse box under the hood shows which fuse goes to what and gives the proper amp fuse. Not sure where it is in a 300D. Maybe that is your problem.

That said I am not recommending that you over fuse.

Thanks I actually have overammped at the moment so they don't blow every time I simply try them
