I am sure it is the AC drain water but its not coming from the drain pipe under the truck, it is leaking from under the uder wrap as i would call it the heat shield or sound break that is stuck to the bottom of the cab. It tracks down the firewall and leaks out from under the wrap and drips onto the transmission crossmember so that is what got me to look into it further and i think it is the AC pipe is clogged but how the hell do you unclog if it is that. Any help is appreciated.
