I'm yet to take the car to the garage (this coming weekend), but I was wondering if there is a guide on how to test the horn? If I'm not mistaken, you can apply volts directly to it and test if it works?
Just thinking it will be easier if I test that and if it doesn't work I can tell the mechanic what I've already done and at the same time I'll also be learning how to fiddle with cars a bit more!!
Edit / Also, while I'm here... After driving for about 30-40 meters, wheels/brakes are making a really high pitched 'grasshopper'-sounding noise which stops immediately when the brakes are applied and starts again when I lift off the brakes, is this a warped disc maybe? ..Cheers!
