I have a 98 SS. One of the horns went bad. From under passenger front I dropped the plastic and found the bad horn. Also, there is a small vacuum canister, maybe 2" dia by 6" long with a small broken line coming out. The other end goes into a wiring harness by the battery. I lost the line at this point. Does anyone know what it is for. I did patch it with a slightly bigger hose and siliconed the edges. Everything worked before so I did not see any difference.

 

I am not at home right now , but did you see the manuals in the manual section? There is also a PDF of the parts manual floating around the net.
