I just recently changed my heatercore about 3 months ago. All went well, no more coolant smell after turning on heater. I have pics if anyone is interested in the job. Anyhow I notice now that it is rainy season my driver side floor under the mats feel as if someone poured a gallon of water on them. I thought maybe the floor was somehow leaking when I drive, leaking into the car from the ground, but then thought it would have drained back out the way it came back in. So I just re adjusted my door seals to see if that fixes the issue. The odd thing is, the water is right in the middle of the carpet so Im not sure if it drained down the door seal and didnt touch the un taunt carpet near the door, and just settled in the middle or if something more is going on. Anyone have any ideas?
