Hi without knowing the exact routing of the heater hoses, it seems quite obvious there is a leak in the cooling system to the heat exchanger (on the inside of the cabin). Generally you could find it behind the dash. Just an advice recheck the coolant level to avoid further damage before repairs are done.

I have a 2000 chevy blazer 4.3 auto my windsheld builds up with steam i change the thermostat thinking it was that but still steaming up the windows


Hi, if it is steaming up the inside of your windows, you have a water leak in your heater core. It is located on the passenger side enclosed. Check you water level also. You can try adding some engine stop leak, a good brand is Bar's leak that will seal any small leak which is what you probably have. Make sure you are running a 50?50 mixture of antifreeze. Good Luck, and please let me know.

Steam fills car when i turn on the rear heat liks water have just replaced the thermastate thinking that is why linking no sing of any leak when hood is raised around the hoses or raidiator


It sounds like the leak could be under the passenger side dashboard which is where the heater core is located. The heater core a small radiator that a fan blows air over to heat the inside of your car. Is the steam coming out of the vents when you turn the heat on?

Antifreeze/coolant leaking from under passenger side dash


If it's your heater core, unless you're a mechanic you probably should get professional help. The heater core is located on the firewall and many parts need to be replaced to get to it. Do you see water on the floor inside the vehicle, Many times a heater core will leak inside.

Heat


So I am guessing the heater core, the only other thing it would be would be any leak that is allowing moisture in the car. is the floor board wet on the passengers side?

Brake Lights Confused


Make sure you have the right bulbs in the back. it sounds like a cross feed.If the problem isn't there then i'd say the turn signal switch is bad.
