Problem: Windows steamed up like at Lovers' Lane

[gusopenshaw]

Regrettably I'm usually alone in the car. Always, there is light moisture on the inside of the windows. I don't think rain is getting in anywhere. The problem persists even when it hasn't rained in a week and the car has been parked windows open (in Alabama). The heater does not seem to have any water in it. I'd appreciate any thoughts.

i'd check for wet carpet & or underlayment....something inside the car's wet causing the condensation

I'd be inclined to believe there may be a small leak in the heater core.

I've checked the floor/under the carpet like a bloodhound. I'm interested to know more about why you suspect heater core, Bob, and what to do about it. Thanks.

A small pinhole in a heater core will do exactly as you describe.

Try bypassing it and see if it goes away. Just pick up one of those bypass pipes from your local parts store ( usually in those stupid red HELP packages ) just find the right diameter and hook the heater lines together ( motor side please ), just leave the heater side open.

If your problem magicly disapears I believe you have a bad heater core my friend.
