wet passenger side floorboard
i have a drainage/condensation issue when i run the ac. water is slowly leaking into the passenger floorboard making it a damp moldy mess. is there a drainage hole or something that maybe clogged up.

Yes, all vehicles with AC have such a drain. When the drain clogs the drip pan overflows onto the floor. There is a hose from the drip pan down to under the truck, if you can find it you can poke a flexible wire up to unclog it.

Unless someone has added an elbow and hose to it then all you should have is a thin metal tube sticking straight out horizontally from the fireline on the passenger side. Others have mentioned their drains being clear of any debris but the wind from driving down the highway pushing the condensation back into the cab. If that’s the case, consider buying a rubber elbow with extension to slip over the drain tube to direct the flow downward

Your third brake light is probably leaking. The drain tube is approx 1/2" diameter and is at the end of a sloped gutter shaped formation below the a/c condenser in the heater box and usually clogs due to molds/algae etc. not from wind. It is located behind and below the a/c evaporator which is against the firewall next to the turbo.
A leaking HMSL will appear as a wet carpet under the passenger side seat. If you pull the carpet down at the firewall on the passenger floorboard you can locate the inside of that drain tube. place a paper towel below it to see if it gets wet just to make sure.....
