1996 Buick Riviera Q&A
1996 Buick Riviera Question: Water unter the passenger's side carpet.
The A/C evaporator drain may be plugged or disconnected. I'm not sure exactly where it is on this vehicle, but you will want to check on that. Peek up under the dashboard, on the right side, on the bottom of the heater box. - lawrenceg
Hi, Because you said "clear water", we'll rule out a leak in the heater hose. So the next obvious "source" could be a leak/tear in the weather-stripping. Not knowing where your battery box is....I'm guessing water/rain is getting into the engine compartment AND is probably coming in behind the dashboard and traveling down to its lowest point (under carpet - passenger side). Pull up the carpet, dry everything, then place a couple of dry paper towels on floor.....then use a hose or carwash with doors & windows up tight. Look to see where the paper towel gets wet 1st...and try to locate any additional wetness! Good Luck! - callhow - callhow
