The other day my passenger front turn signal bulb blew. I changed it and within seconds it blew again. As I was going to try again, a friend of mine noticed this thing and the cap was off. I experimented and with the cap on, everythings fine. With it off, the bulb blows everytime.

heres the link to a pic:http://www.imagestation.com/album/inbox.html?id=4289238851



Thanks

Yes, it was a short I am sure, but why when this cap is off? The cap has metal contacts on it and in the part it screws into. If you are standing in front of the car, there is a big empty space in the engine compartment closest to the passenger side. If you look in this empty area you will see a round black cap. Unscrew it and lift up. I tried to attach the pics but got a message saying no attachments at this time. Thanks

Thanks Davy, nothing is wrong with it except the cap had popped off. It seems if the cap is off, your passenger turn signal blows. I took the cap off, started the car, and sure enough blew the front turn signal, just to see if it would do it again. I guess it wasnt screwed on tight and the cap just popped offby itself last time. Thanks again, had me stumped as to what it was.
