weird electrical problem ?
 

ok well first im new so hi to all and i am a new owner of a porsche 1983 porsche 944 and im proud to say its my first car! i love it but i need some help. ok at first things in my way are the horn and wierd lighting at first we found out the horn doesn't work so thats 1 thing thats in my way to pass inspection and the other is lights we thought it is the switch so we cleaned the contacts and switched and we messed around with it and nothing so i drive it anyway around the house and around the roads so i can get familiar with and learn stick (im not to bad) so when i got out of it i just put the lights on to be dumb and it worked as in both lights started working (only one worked at the time) but now when i look at it one is on brights and the other is dim and when you try to hit the brights the left light goes out completely. so i dont know if if there a related problem or a electrical problem or the switch so if someone could shed some light that would be awesome i have some more problems but there are not in the way of getting it on the road
