The heater in my 90 Geo Storm smells like urine the warmer it gets. When I first got the car a few months ago it was VERY strong and since running it, it has very gradually lightened up a little, but is still strong enough that I really need to find out what is causing this so I can get it fixed. Nobody will ride with me because it stinks! It's only when the heater is on, and the hotter it gets, the stronger the urine smell. Any help you could give me would be greatly appreciated.
