just recently got a 02 v6 mustang, and just the other night this happened. when i turn on my headlights in park or neutral it makes a grinding noise, but doesnt make a sound in drive or reverse. and my windshield wipers dont work anymore. please give me an idea

 

where exactly does this grinding noise come from? im assuming the front of the car, maybe due to the strain on the charging system when you turn your headlights on. does it grind every single time you turn them on? and could be a bad switch or fuse for the wipers. not sure if the wipers have their own fuse or not

 

yes every time i turn them on it makes a grinding noise. and when my engine is off and i turn them on my car starts to try and crank up, without the key in the ignition

 

i do believe that your headlight wires are crossed with the starter

 

ok so i can turn the head light on with the dash lights turned all the way down and its fine, but as soon as i make my dash a little brighter it does it. so its my dash lights not my head lights. so could my dash light wires crossed with my starter?

 

can't say for sure without being there to test it but if the engine starts to spin when the cars is off and the dash lights are turned up id say so, also explains the grinding, when the car is running and you try to engage the starter it makes a good grind

 

yeah thats the sound it makes if you try to start the car while its started so how should i go about looking into this where would i look

 

had anyone work on your car lately that would be related to the problem?

 

nope ive had the car for only two weeks. and all i did was change battery and change some fuses

 

any ideas
