It will be on the lowest point of the HVAC housing at the firewall. It is easiest to clean using compressed air.

Thanks, I will wait to be back in my garage to have a look and try to access the drain! Humidity is reducing with the weather but still is in. I'll try and keep you posted if I find something related to the drain.

Thanks again.

Hello,

After doing some research I found that my heater core was leaking enough to creat fog in the cabine but not enough to leak in the foot well.

So I ordered a heater core on rockauto.com with a fuel filtre and studied the diy's on this forum. With a friand of mine it took us 5h to change the heater core and flush the entier colling system to start with som brand new dexcool.
While we were there me changed the engin oil and filter, greased the front end and swaped the tires.

The leak on the heater core was very small. A tiny crack near a solder that would leak only if very hot.

Every thing works fine after the swap.

I wanted to thank you all for the precious information regarding the heater core change.

By the way my blazer is a 2002 4 door LT 4x4 with 123000km.
