Trying to access the Brickboard is similar to buying a lottery ticket! After two days I am able to get on and make a post. This is an update to my original posts at:
https://www.brickboard.com/RWD/volvo/1692758/update_power_window_30_amp_fuse_blowing.html

I had determined that the fuse would not blow if I operated each window from the switch on its door. After getting the car to my work area I was able to operate all the windows (including the driver's) from the appropriate switches without the fuse 8 failing. I tugged and pulled at the wire bundle going from the door to the body while operating the windows and all seemed fine. I added a little load on the motor by using my hand to increasing the resistance on the glass movement with no effect.

I took the block of switches out and took the driver's switch apart to clean it up. Two of the four contacts were black from arcing. I polished all of the contact areas and put it back together for good measure. My experience in the past was that when the contacts were burned like that the switch simply wouldn't make a connection and the window motor failed to engage.

I also found that I had misrepresented which fuse was showing signs of having been hot. It was not fuse 17 it was fuse 16 which is associated with the blower motor. I am confused as to why there are two fuses listed with the blower motor both 16 and 6. That is a mystery to be explored at a later date.

Thanks for the help in chasing the fuse 8 problem. My experience is that electrical problems seldom go away they are just intermittent. So until the next time.....
