Hi, I have a problem here. I was trying to drill through the firewall in my 97 expedition. I was drilling on the front passenger side where the floor starts to curve up and head into the dash. My drill poped through to metal and hit something else I guess. All of a sudden a green form started coming out. It sounded like air was escaping. What did I puncture? I have no idea and could really use some help. Thanks a lot!

 

Sounds to me like it could be A/C Oil for the A/C I know this post seems to have been up for awhile now and I am sure you more than likely got it fixed by now. Not to make things worse but that's why you don't just start drilling where ever. You always always check what is behind where you are drilling and double check it again and if there is any doubt about what is behind where you want to drill you DON"T do it.
