2006 Mustang GT Electrical Problem

[kargan]

Wondering if any of you have seen this before.

I have a brand new 2006 Mustang GT Convertible that I have owned for a week. After 6 days suddenly the top wouldn't raise or lower and the power windows wouldn't raise a lower. I took it in to the dealership to have them check it out and they found it was a blown fuse. No big deal, they swapped it out and it seemed to work in the parking lot. I drove it 40 minutes to home, pulled into the garage and figured I would try the top and windows again just to be sure -- and they didn't work! I popped open the hood, tracked down the fuse they replaced and sure enough it popped again. So I swapped it out with my own fuse and got the top up. I raised and lowered it several times while idling in the garage, no problems. Wife takes it out, top goes down, gets to the store and the top won't go up -- same problem -- blown fuse.

It's now back in the shop for them to evaluate. So far they cannot reproduce the problem. I am thinking somehow it's related to driving it though I cannot imagine why. They are trying different combinations of accessories and cannot reproduce. I just know if I pick it up and drive it home it won't work again.

Anyone had this before?

If it helps the fuse in question is the 'delayed accessory fuse'.

Thanks!

You've got a short to ground somewhere in that circuit.

Its probably related to either heat (when things get hot, they expand) or vibration.
