Okay I checked all my fuses and they all seem to be okay. I figured out the wire for the horn is attached where it is supposed to be, but I don't know where to hook it up. When it touched metal it would beep, but for some reaon know it just clicks and doesn't beep. Thats one problem, another is the the low beam hedalights. I pull the **** and they do not turn on, when I turn on the high beams both the high and low beams come on as they should. I was wondering if any knew how to fix it, I'm guessing it has something to do with a loose wire. The washer fluid isn't squirting also. When you turn it on the wipers go and you hear a buzzing noise but the washer isn't being pumped. If anyone can help me out I would greatly appreciate it. I just need to know how to go about fixing these before I start ripping things apart. Please help me
