On my 98 Volvo S70 how do you fix the master window short affecting the four windows and the sunroof switch goes limp on the dash with that window failing to work as well My mechanics are stumped.?

I don't think these are related issues, but I could be wrong... only because I know I cannot open my sunroof (it will not close then...) so when my window switch bank crapped out, that is what I replaced and it fixed the window issue. The window switch banks are VERY commonly replaced. I sent my broken one in and I was sent a refurbished one. This is better than the crappy aftermarket ones, which i tried twice and they were horrible!! I finally sent mine to Swedish Car Parts in Chicago. When the wierd guy on the phone told me he could fix it I was a bit hesitant, but I am happy with my "new" used switchbank!It WORKS and has for over a year. What more can I ask for?????

These may actually be related issues. They all happened at exactly the same time. On my 98 Volvo S70, a broken switch on the Master Window Control Unit caused a window to be constantly engaged. This may have been what caused a relay in the fuse panel (under the hood) to become very hot. My problem is currently unsolved, but this is what I know:

- The fuse labeled "sunroof" is fine. The dash lights go out when it is pulled.

- The power locks function properly.

- The Rear Lockout Rocker has no effect.

- The power mirror switch also does not function.

- When the Master Window Control Unit is physically disconnected from the wiring harness, the fuel door does not operate - but it works fine otherwise.

- I replaced the Master Window Control Unit with one from a junk yard which provided no remedy. Perhaps both are defective.

- The relay under the hood that had become hot has been swapped with it's neighbor (assumed to be functioning) which provided no remedy.

Can anyone offer any other missed opportunities?
