discovery 1993 300tdi indicator lights stuck on

hi can anyone please help

all six indicator lights are stuck on and wont go off
i have removed fuse in fuse box and all the lights go off but all starts working normal but i then loose the electric windows blowers and sterio

its really being a apin now over christmas

please please all ideas welcome

All indicators?
Hazard warning light switch??
Pull the switch out from the dash and disconect the wiring plug - see if it stops

they dont flash they just stay on so would that be hazard light switch

might be the hazard relay stuck in 1 postion OR could be the indicator stalk on the steering column

ok update removed hazard light switch but lights still on and staying on

if it was indicator stalk wouldnt it do it all the time becasue when that fuse is removed it all works fine but electric windows dont work or heater blowers

Haynes manual wiring diagram no3
Looks to be a simple circuit - looks to be the direction indicator flasher unit (no 48 on diagram) thats at fault
Switch on the hazard warning switch and see if you can hear the unit clicking - if not remove the unit and give it a tap and replace it and try it again.
