wet carpet cure =

95 olds acheiva gets wet carpet on passenger side when it rains. appears to be coming down from firewall. anyone seen this before?? sounds lkie i need to pull the cowl cover and check drain and also for cracks,etc.??

I don't know if this helps at all or not, but I've read that for leaky sunroofs, it could be a plugged drain hole, which can be solved by running weedwhacker line into the hole to clear it up.
