I discovered coolant seeping at the bottom of where the blower motor fits into the HVAC housing.
I BELIEVE its the heater core thats leaking-I have never had a vehicle leak like that-all of them seem to leak onto the passengers side foot well.
About 6 months ago I had my water pump and ALL hoses replaced, so sure don't suspect them.
There is no coolant anywhere else besides at the bottom of the blower motor housing in the engine compartment.
I have watched SEVERAL videos about replacing the heater core and none mentions where they discovered their leak.
Anyone had this happen?
A coolant leak at the blower motor isn't a normal thing since the heater core is inside the cab and lower than the motor. You'd have a heck of a time convincing me that the heater box could get that full of coolant without leaking somewhere else first. The evaporator drain tube would let it all out first.
The heater hose connections are the only things coolant related that are even remotely close to the blower motor but they're even quite a distance.
Are you sure that it's not AC dye? It's green too and a whole lot closer in proximity to the motor (the evaporator can actually be touched with the motor out).
The evaporator coil drain is above the passenger side leaf spring on a 4x4. The mounting point is the same for a 4x2, but I do not know the orientation to the springs. It is difficult to see at times. Check to make sure it is not plugged up.
If you decide you want to crack the box open and clean the evaporator coil and clean the drain from the inside, check out the video below.

This was my first thought as well...
Supercab, is your coolant green? AC lubricant oil usually has dye in it that is also green. Hit it with a UV light if you happen to have one and see if it's florescent.
Is your leak a seep, or a gusher? If it's pouring out gallons then it's obviously not AC oil.
Wow!! Thanks guys for the replies. I run the Peak Final Charge coolant so its Red.
We were changing the serpentine belt and noticed the reddish wetness coming from the bottom of the blower motor,
We have owned the truck for over 15 years and the a/c has never been touched and blows 38* at the vents......IF there is dye in the a/c system it was put in LONG ago before we bought the truck.....
I thought it was very odd myself........
We are going to take a 200 mile trip today so I'll keep an eye on it.....
