hi all

I have a x(2000) lx 1.6 petrol picasso i have recently bought it, there is a warning light coming on saying abs fault and the temp gage is saying hot all the time even if the car has been stood for hours, also my indicators are not working and my wipers and the central locking is not working.
Could anyone help please.
