Well after 4 hours of tearing components out and well alot of swearing I came to a couple of conclusions about this issue.
1. Only take your Subaru to the dealer if you do not know how or do not want to work on your car
2. Bad placement of hoses and equipment will make issues like this arise
3. Putting electronic equipment under components that leak fluid is a big no no.
4. Blow out drain hose every oil change
I think the reason my floorboard was soaking wet and there was water coming from under the dash (ie, heater core, vents, switches, and any piece with a crack) is because the last time I took the car to the mechanic, aka Subaru dealer aka Satan for this exact same problem I come to find out that they forgot to put the drain hose on the pan my opinion. So tearing the whole compartment was not a loss. I did find out that water can leak in from the vent where the car gets it's air from under the leave guard under the hood but that would mean that the drain holes will be clogged.
After ripping the entire passenger area out of the car to find the leak I found out where the ECU is located, ironically it is under the kick plate on the passenger side of the floor board right under where a lot of water will collect is you drain hose clogs up. Also who ever designed the heater core unit mounting casing should be shot as there is one bolt that is at the top of the dash that only a 7 year old can fit his hand in there and if he does it will take him 15 minutes to unscrew.
This is still to be continued because I left the passenger side apart just to make sure that this was the culprit and it is supposed to rain tonight.
More to come.....
