If you can identify where the a/c lines enter the firewall on your truck, you can look down below there and you'll see a collapsed rubber hose that sticks out.
You can squeeze the end of the hose and it should open up.
If you have a drainage problem with your a/c you can use a small length of 1/8" copper tubing to probe into the hose to check for blockage.
If this hose is clean/clear you may have a problem with your heater core, more likely this time of year in the U.S., this core could be leaking.
To find out for sure, if you have a leakage problem, taste the liquid or at least smell it.
If it tastes a little oily or smells sweet, it's Radiator Coolant, providing you use it like you should. If it's bland tasting, like tap water but without the taste, it's probably condensation from your a/c that has backed up due to blockage.
If you can't identify the problem using this little tutorial you may need to take it to a shop and have it checked out so you know for sure.
If it is a leaking heater core, you can change it yourself, and do it safely, if you do a little study and take your time doing the job as it's not difficult, just time consuming and a little dirty.

it should be on the passenger side down close below the firewall.
