Hi guys recently brought a ls400 on a k plate the car was fine for a day then the battery died i replaced the battery and it has been fine until i got in the car and there was no igntion lights but it still starts and drives,but there is also alot of stuff not working ie radio,heater,rear demister,mirrors,windows,wipers but all these where working fine until i started the car with no ignition, is this just a relay or a fuse any help would be most grateful thanks
