I have a 2002 cavalier. The passenger headlight doesnt work at all. The drivers side only the high beam works. The daytime lights dont work at all. I changed the switch. Checked the fuses. Not sure if it could be related but the horn doesnt work and I have had problems with the battery. The battery is only a year old. Sometimes I have to jiggle the battery around in order for the car to start. Ive already cleaned the battery terminals. I had a remote starter installed 2 years ago but havent been using it since january.
