Your heater core has a leak, it's like a small radiator that heats up and the blower motor blows air thru it to create heat in the car. It is leaking anti freeze into the heater box.

I just put a bypass hose on my 91 Buick lasbre and turn on the heat and started seeing steam come out the vents and now its steam on my windshield


Sounds like you have a bad heater core or you have antifreeze leaking in the into the heater box. Maybe a loose clamp on the bypass hose or maybe you damaged the heater core tube when you installed or removed the bypass hose and now it is not sealing properly.

I have smoke coming out of my air vents even with the heat off.


Do you see antifreeze dripping or a fogged windshield? If you do, it's a probably a leaky heater core.

I have a 2000 4.3L silverado. Heater & AC works but when defrosters are turned, on my windows fog. Why???


Check coolant level, if it's losing coolant, you may have a heater core leak. Does it smell like antifreeze in vehicle when defroster on? If by chance your ducting drain is plugged, it may just be water or condensation build up inside where core is. Antifreeze leak will also put a sticky film on inside of windshield, so if you wipe it with finger and it feels sticky, it may be a core leak. Be sure to double check heater hose connections in to firewall/heater core, just to be sure your leak isn't a bad hose connection before going to far if core appears to be leaking. A pressure test on system may give you a better idea what's going on. If all checks out and no leak apparent, be sure your AC compressor is engaging when in defrost mode, as that is what helps remove the moisture in the air during defrost. If compressor is not engaging, it will take much longer to remove moisture in the cabin.

Why my window is fogging whe i turn the heater ?? i recently bought my toyota carina 3 model 1994 but the window is fogging , what should i do?


Make sure the vent system is set to draw air from outside. If it is set to recirculate the same air that's inside the vehicle without drawing fresh air from outside, the resulting humidity that builds up inside the vehicle can fog the windows even when you run the defrost. You can also try opening the windows a bit to get some more air moving inside.
If it still fogs when the vents are set properly, you may have a leaky heater core. The heater core is a small radiator that is located under the dash that the heater system blows air through to heat the inside of your car and provide heat to defrost the windshield. The fog may be coming from the heater core leaking hot coolant steam that's being circulated through the defrost system. If this is so, you will need to replace the heater core.

My front defroster is not working at its best, however the back one is working properly. If I add any heat while trying to defrost my windows the problem get worst.


Sounds like the heater core is leaking coolant. If it is leaking it will blow steam out of defrost vents and fog the windshield. Symptoms: low coolant level in radiator, steam coming out vents when engine is warmed up, odor of anti-freeze coming out of vents, wet carpet in floorboard near heater blower motor.
If so, replace heater core.

Steaming from back of the engine. no heat. windshield fogs in the inside


If you are loosing coolant and you see water under the car after sitting you have a leak. The most likely area is the heater core as you are getting steam inside the car. If you smell anti freeze that is another confirming item. Check all the hoses and connections first before replacing the core. Good luck.
