nothing major I think...

while driving on the local interstate.. 60-65 I realize my a/c is no longer cold, which really sucks because it worked great.. I turned it up and down just out of curiousity and while on the highest level it blew cold for a little bit.. at a stop light I saw white smoke coming up from under the hood.. so I freaked out and immediately pulled over.. came out to be a white smoke with a distinct odor coming from behind the intake manifold.. and there is some residue on my strut tower brace and around that region that is fresh.. only does this when the a/c is on

could this be a coincidence ? or is it related.. I really hope its related.. fixing a/c is alot simpler then who knows what it could be
