Question about 2001 Honda CR-V
I think my heater core is starting to go bad.Now that winter is here,the defroster has to be on high all the time to keep the windshield clear while the other windows fog and ice up on the inside. I do smell a faint smell of anti-freeze, but have't notice any leaks or low coolant leavel. I did but some of that "raditor fix a leak" in the other day, but that didn't help. I guess the next thing to do is to replace the heater core. What's the best way to get to the core? I have the problem with the windows fogging up inside but I don't notice the smell. Any answers?
Try looking at the air filters. MIne was totally clogged with ****. No air circulaton equals foggy windows

If there is no coolant loss and the rugs under the heater box are dry, Depending upon design, the vent for your air conditioner (a small hose that empties water from the a/c evaporator, back outside the firewall) may be plugged. They can be cleared by using compressed air (even a bicycle pump will work if not too plugged) DON'T stick anything sharp in there or you may damage important stuff!! Only one thing: If there is water in there and it's frozen, it won't come out till it's thawed!!

The early sign of a heater core leak is the smell of coolant, the reason is that only vapor is leaking now, it will gradually get worse in most cases and coolant will start comming out the heater box condensation drain.
