You'll probably be colder than normal.
If it still blows cold when it is at running temp, check the engine thermostat, its probably stuck in the open position.
the humming sound is causing the heat? Your fan clutch has failed, or the radiator/condensor have dirt blocking airflow.
IF YOUR CAR LEAKS WATER AND HEAT BLOWS COLD AIR WHAT THE PROBLEM

the ford 99 is a younge truck and if it does that then you need to get a new heat/air conditioner you might need to get a new truck.
heat the cap up with a turbo torch and burn the plastic out of the cap groove.
yes However, it is not recommended .. so the damage needs to be in front of the shock mounts .. and only heat to a soft red color
make sure both knobs are all the way up on red for heat...
