Water Leaking on Passanger Side Floor, but it's not antifreeze!
Just recently I have noticed an appreciable amount of moisture underneath the floor mat on the passanger side of my 2006 Trailblazer EXT LT. It is not anti-freeze, so I am ruling out the heater core. I was thinking either a clogged drain line for the Air Conditioner, or a leak in the firewall.
Did anybody have this experience with this car? Any remedies?

Have you been adding a little more antifreeze recently if so check the floor on the pass. side,if it is wet your heater core is leaking.That will also cause the excess moisture on the inside mostly on the winshield.
Check heater core hoses thats where they are you just may need to tighten but check the pipe fittings to core and check if the inside floor wet middle passanger side that would mean the core is leaking
Hi , Its leaking water on the passenger rear floor? It could be the heater core leaking and running down the floor board to the rear of the vehical. Do you smell antifreez or see moisture build up on the windshield ? does the car seem more "humid" inside?
You will also smell antifreeze/Prestone Sweet smell if the heater core is leaking and the windshield will steam up in cold winter not to mention the obvious coolant loss. i would think if it's water, unless you are using water in the cooling system, then it could be caused by the AC when it's on. This is normal for the hoses to have moisture on them and you will see it on the ground underneath the car when the AC is running.
Is there a sweet smell inside the car?Heater core leak I beleive would be on passenger side floor.Antifreeze will be sweet to the nose.Are you getting any white smoke out the tailpipe? would likely be head gasket leak.Put a piece of cardboard under the car near the radiator and under the motor to see where its leaking from .One thing Ive learned over the years is that its going somewhere.On the ground? Or out the tailpipe.
As for the floor board leak the 98 s were prone to have the defrost area in front of windshield collect water from being plugged up .Mine was passenger floorboard.Daughter resealed small oval vent (that defrosts /heats hood?) LOL .Its on pass. side under hood on cowl .I think this will take care of my problem but you may need to investigate under the dash/defrost area and drill and then install a drain line to bottom of defroster.Exit drain line to O/Side of car...lol .Also was it raining ? was car outside in rain .if so it could be this issue.Sorry so long ,hope you can make heads or tails of this.
