Where is the drip port on a 02 sport

I'm looking to clean out the vents on my rig and I bought that kool it stuff on Amazon for it but it asks to inject the foam through the drip port from the heater core

Does anyone know where that is? Or what it looks like?

I checked and apparently it's suppose to be by the passenger side firewall but I can't see anything that resembles that port for the foam

Are you talking about the drain for the condenser? That's by the passenger firewall, but it has nothing to do with the heater core...
 
Assuming my '97 and your 02 have the same design, look carefully at the firewall, way down low. Mine came to me w/o any hose. It was just a rubber port, flush with the firewall. Very hard to see. I stuck a hard plastic hose corner in it and rigged my own drip hose. The drip hose now comes all the way down to the bottom of the frame rail. Made it easy to pump in the spray.

Can't you just shoot the stuff through the vents and then see it drip from the drip port? Could that work??
 
Just found a article online and decided to check out my firewall... is this the port that you're talking about?? It comes up right behind the ac-heater core

If your vent ducting is like my vent ducting, then NO.
The ducts are made of a cheap, too-thin PE plastic that warps over time and forms many, in some cases large, gaps between segments. Spraying the stuff in the dash vents could leak cleaner stuff under the dash. Find the drip duct and do it right.
 
It is by the passenger's side firewall. Best accessed from underneath. Looks like a 1/4" or so rubber tube, or hose. Mine was of the same color of the body. Btw 02 Sport as well. About 2 years ago it got clogged with dirt and all the condensate was spilling in the cabin. I had trouble finding it, but this forum helped. Again, bottom of the firewall on passenger's side.
I hope that's the thing that you're looking for.

The drain should already be open... that's why it's a ... drain.

OP is also confusing the hell out of me.
