1996 Chevy Silverado V8 Four Wheel Drive Automatic 218000 miles
Whenever it rains (I live in WA state, so it rains a lot) I have water in the housing for my heater fan located under the glove compartment. I have tried flushing out the outside vents under the windshield, but water seems to keep getting in. It has not created a mold problem. What could be the problem?
