The door is not loose. But I have a friend who has an older 1500 Silverado and he said it was his heater core but I didn't know if anyone with a blazer has had that problem or at least heard of the problem.

F your not losing rad fluid, and your heater doesnt lose heat, then I would say it's either the door weatherseal, or check your undercarriage for a rust hole in your floor. Might be coming up from the road while driving.
if you notice it getting wet on dry days, then I would say you have a small leak your your heater core.

The easiest way to tell if it's a heater core leak is to see if you've lost any coolant in the radiator. You can run a finger in the wet spot and stick it on your tongue. If it's coolant you'll know. My leak was so big that the inside of the windows fogged up when running the defrost. Pray it's a door seal and not the heater core......

check the carpet on the middle tunnel.
The heater core is inside a casing which in turn is hidden behind a cover above the right hand foot of the passenger side on the firewall below the dash.
The casing of the core itself leads to the center console and HVAC. If it leaks sometimes the coolant runs along the seam and drips down onto the right side of the tunnel in the middle. Also by prying back the carpet you can feel if it is wet behind. If there is moisture or even wet in the middle of the passenger side at the firewall it most probably is the core.
When the truck is warmed up and with the engine running you may run your hand or a towel along the under side of the casing. Kitchen paper does a good job in detecting any moisture. If it is a real leak you can feel the warm water.
The cores can leak from just moisture to a steady drip.
Just put my repaired one back into my blazer one week ago. PITA the first time you take it apart.
