Ok most of you that are on this bbs all the time probably know that my starter went and I had to replace it but it was making noises. Well, I figured out that it was not catching the flywheel, i think that's what it's called, right, so I put to Z shims in and walla. Well when I was looking at the starter from the passenger side outside, looking down towards the starter, I noticed a tube coming out of the firewall that wasn't connected to anything. I looked and the closet thing I saw next to it was the intake manifold I believe. I thought it might be the problem for my ac. My compressor works and I can hear air moving but it is barely coming through the vents into the jeep. I turned ont the AC and I felt cool air coming out of this mysterious tube. I tried to look though my Haynes but didn't find anything. Can someone with an 2.8L XJ please stand on the passenger side of the jeep looking down towards the starter. There is a black tube coming out of the firewall down almost by the starter. Can you see where it goes and report back. If you already know what I am talking about don't bother checking your car. I thought tracing it would be easy though. Thanks a lot.
