I have condesation leaking on to the passenger side floor while the A/C is running. Looks like it is near the transmission tunnel. Any ideas on the fix?

 

First I would make sure the condensate drain is not plugged or missing. If thats okay I would start looking for cracks in the housing.

 

mine has been doing the same for years, just started again this week. The first time it happened was years ago and we were on the road so we pulled back some of the carpet and located a crack that was leaking it into the cab. All we had with us at the time was silicone sealent so thats what we used. While it is a good temp fix it seems I have to re-silicone it every year now. Doesn't take much time and its cheap so I just do that about every year or so now now.
