Rover metro Full Beams lights and wipers dont work?

I have a rover metro, 100 ascot when i first brought the car my lights began to play up. The dipped head lights would work and high beam but for them to come on normal i would have to sit there for about 3 minutes for them to click on themselves and as they would come on u would hear a click so we changed the relays and still the same today. Also i brought myself a new car in january and stopped using the metro it was parked up on the drive after afew months we started it an changed the battery and got it working again but the wipers have completely stopped working and also the heater has stopped working. Ive changed the fuses under the steerin wheel and ulso the fuses under the bonet. Anyone got any ideas to what it may be??? please help
