I just purchased my '04 Vibe in May. About a few weeks ago, I noticed this smell that would come out of the vents when I turned on the A/C. The only way I can describe it is that it smells like urine. After running for a minute, then the smell will dissipate. Has anybody else experienced this problem? Can it be fixed?

I am so glad to hear that I am not the only one with this problem. I purchased a 2004 Chevy TrailBlazer in Nov of 04 and I have the same problem. Everyone that I tell thinks I'm crazy. Did you find a solution.
