1999 Escort Finesse TDI Estate, no sidelights, but headlights work ok?

Hi I have a 1999 Escort Finesse tdi estate, the headlights work ok on dip and main beam, however the sidelights front and rear dont work and neither does the instrument lighting. I have checked the fuses with a tester I believe its fuses 4 (lh lights) and 7 (rh lights), which I checked with a fluke 25 and am getting 12.5v on both sides. i have checked the connections on the fuse box all seems to be ok and ive changed the lights/wiper arm switch assembly for a new one but still no side lights. Any ideas would be helpfull please.
