Lights and horn problems and Idle problems too

bobbymarceland

Well i got a Chrysler plymouth grand voyager se 3.3l v6 first thing is the lights are stuck on i tryed replacing the fuses and replays thinking thay were broken but that didnt help then i noticed once i took off the fuses and replays the passenger light is stuck on so i was thinking a faulty replay on fuse, but then now we have the horn its stuck on won't turn off once i pull replay it turns off could it be that the horn may be stuck if so how can i fix that, and last idle problem its might be just a throttle sensor or co2 sensor well it idles fine once started but 1-2 min it starts to idle below 0-1 which i know is unusual then after 3-6min it highs up to 2rpm then back to 1 and remains there for the remainder of time its started. Anyone have awnser please help me out

loose ground wire can cause those electrical symptoms. an oxygen sensor can cause the varying idle. so can failure of part called idle-air-control valve or pump.
