I have a water leak showing up under the passenger carpet. It's not radiator coolant. It seems like rain water coming from the vents after our recent heavy rains in So Calif. Is there a common problem with the air ducts in this model truck?

I have 1999 chevy truck believe its leaking around where duct work goes thru the cab. Have taken it apart have not got it together but looks like it could be from there. Pulled carpet and repairing rust now. Can't post pics but cut around the plate cover right above the vent opening. And seal around opening and seal the cover back down.
