Power Windows Not Working on 2004 C70

Hi all, first post - I have a 2004 C70 and yesterday all the power windows stopped working as I was driving it. None of the windows work from any of the switches nor does the 'all down' switch work. It looks like the only fuse is a 60A fuse in the main relay panel (could be wrong). I tried disconnecting the battery to see if it was a computer issue with no luck. Any advice?

Thanks!

That switch does fail on time, and it carries the current to all the windows. You can pop it up out of the arm rest and get to work with a Vom,

A new one is about $150

Have a look at fuse 15.

Abscate is right about the master switch being a common issue
with most 70 series cars, but the drop-top is a different animal.

On your convertible, the master switch is a more of a controller.
It sends low voltage commands to a relay module in the dash to
actually operate your windows. The 'vert master switches usually
live longer than the S/V switches, but are NOT cross-compatible.

main fuses in the box by strut top in engine bay on driver's side has #2 and #7 which also have power feed into circuits.

Fuses in the box just in front of driver in cowl has numbers 15, 35, 37, and 38 to check.

@Jimmy57. Six years down the line I found myself with non working power windows and power mirrors. Spent hours reading and checking fuses that were labelled as relating to power windows and power mirrors and all were ok. Found your post and got to number 35 and it was open. I couldn't have known that this particular fuse is related to power windows/mirrors. Replaced it and windows and mirrors worked. Thank you so much.
