Side lights, rear lights and dash fuse keeps blowing!

[Deebareen]

I swapped drivers door yesterday for one with a little less rust, same make model and year, all went smoothly although for some reason the back passenger windows are now refusing to work??

Next thing I notice is the dash lights aren't working and neither are the sidelights or rear lights! The fuse is blown, I replaced this but it blew straight away, disconnected the new door and the fuse is still blowing! Any ideas??!!

Thankyou!!
