I have a '97 with 184,000 miles. The carpet is slightly wet on both driver's and passenger sides and is occurring when it's dry outside and without the heater being used. Just had the water pump replaced since it was leaking. Had hoped the water pump leak was finding its way into the cab, but that's not the case. Other posts say the heater core would only be leaking on the passenger side. Is it possible a leaking hose to the heater core would hit both driver's and passenger carpets.
