My R reg xantia estate has big electrical problems all of a sudden. Central locking not working, alarm not working, electric windows working intermittantly and send all the dials crazy when the buttons are pressed. clock keeps going off and on, radio goes off then needs code again. Car will start and runs fine but everytime anything is turned on or off all the dials go crazy so I don't know what speed I am doing etc. Can't open the boot or the fuel cap. Any suggestions as to the cause of all this. The day before yesterday everything was fine. thanks
