So last night I decided to jack up the car and look at some loose wires hanging under my white 1994 XJ12. While I was under there I thought I would also do some investigation about a wind noise I had been hearing from the passenger’s side front footwell when driving down the road. I pulled the front right wheel off the car and started digging about. Just below the bottom of the inner fender liner I found this:

Small rust hole below lower edge of inner fender liner on passenger front of the car

Once I found that hole that was only about an inch across horizontally and about 2 - 3 inches vertically I didn’t think this was enough to cause all of the wind noise I had been hearing so next I removed the various fasteners holding the back half of the inner fender liner so I could pull that away to look behind it. As I suspected there was a larger hole behind the lower corner of that fender liner.

Much larger rust hole behind lower edge of inner fender liner

So I guess I have to remove that front fender so I can get at this and try to make some patch panels and use my mig welder to put them in. Hopefully without burning any wiring or other stuff that is exposed behind this hole.
