I have a puddle of either freon or water in the passenger side floor board, i was told it was the heating coil. what could it be or where is the heating coil.

Don A has an excellent answer, but if you have a sunroof, that is more likely the reason. The pipe runs down between the door pillar and the windshield and there is often a join there which can part. Be careful with compressed air as it can blow joints apart.

you said water, well that can be clean pure water
from RAIN or HVAC evap condensate,
using AC cool or heat + defrost mode? or just pure heat mode?
I do not know what you do there
i tray to capture water,in jar,and see if it is green or yellow or pink
that is AF antifreeze,
and put my fingers in it and rub fingers to thumb and it feels very very slippery, that is AF. not water
if i sniff it and smells sweet it is AF>
(3 ways to discover AF antifreeze)
ok it's water, so dont use AC or Defrost mode.
so that be RAIN or defrost condensart
sorry i could never even guess the water gravity effects from any car made from fire wall to rear of care, gee hills even change that.
learn to do deeper inspection of all carpets there.

bad door gasket
or last drove car with say a bandanna hanging out the door.
a 1 time event,nobody can guess ever.
and allowed rain to go inside any car.
or windows were not fully up.

Have you checked the rubber door seals for ingress?

Not comming from the speaker! Make sure that the rubber door trim aound the door is intact and not damaged. Additionally, check the rubber seal on the outside of the window where it retracts into the door. These are the only 2 ways that water can enter through the passenger door.

It can only be one of 3 things

heater core leaking. Sweet smell an dfilm on windshield

a/c drain plug blocked, not allowing condenaste to drain on ground

water leak though a seam leak on cowl or around air intake under leaf screen at base of glass on passenger side.

Water on the floorboard, usually on the passenger side, is usually an indication that the condensate drain is plugged and needs to be cleaned out on the AC unit. If unit is low on freon, it could be freezing up, causing a larger problem with condensate freezing, then draining onto the floorboard.

Highly likely they are related. I'd start by clearing the drain, then checking the freon level.

On high fan speed, the air flow may be fast enough t o prevent the freeze up of the coils, at least for a while.

Heater core is leaking.

your heater core is going out its under the dash on pasinger side of you car you shuold get replaced soon it my lead to over heating problems

A/C drain pipe blocked with old leaves and dead flies the outlet is on the passenger side of vehicle lift bonnet and look a lower of firewall for a rubber pipe with a **** in the end and squeeze it and shake it

the heating coil is on the passenger side seems like the house is leaking
