Well as far as the water under the passenger mat it sounds like your heater core is busted.

How is the A/C not working? No cold air through the vents? No air at all? Have you checked to see is the compressor engages?

Before you rip out the heater core make sure its coolant your seeing and not just condensate water. If the drain hose is plugged water will accumulate in the bottom of the box and overflow inside the cab. If your coolant has the proper amount of antifreeze in it then you should be able to see and smell it. If its just water then I’d suspect the drain hose is plugged. If the A/C only works for a couple of days after recharging it I'd recheck the system again and if its low check for leaks.

^^REV^^I will check again today but I think its just water under the mat. I will check the drain hose too, if I can find where its at. I need to drain and refill my ratiator...havn't done that in 2-3 years. But I do know its full and mixed 50/50, and it doesn't leak. Later this week we are supposed to get into the 80's maybe 90's so I will recharge the system, but how would I check it for leaks? Thanks for the help!!

you need to put UV dye in the system, run it and use a UV light with special glasses to check for leaks. the dye will glow under the UV light.

hey fddriver02, whats up with the "ASE= Ask Someone Else" in your sig?

whats up with that?

Any time refrigerant leaks out, oil goes with it.

Look at all the air conditioner lines FITTINGS.
Look at the underside of the HOOD.

Look at the front side of the condensor (radiator look alike that is in front of the radiator).

Last leak spot is the evaporator. Look there if you end up replacing the heater core.


Anyway, if you find a spot with dirt/dust/grime, THAT'S where your leak is. Refrigerant oil is sticky, so it attracts dirt.

If you see dust/dust/grime on the underside of the hood above the compressor - then it is your compressor shaft seal (means replace the compressor).

OKay...I can't tell if theres dirt dust or **** on anyo of the hoses...its all dirty/dusty under the hood...I keep it clean but its been a few months sense i've clean under the hood. But I did notice that I went threw some anti freeze and water from last night to today from about 25miles of driving. Would that indacate anything? No water or condacation under the mat but its also been warm here latly. I am going to fill it up again when I get home in an hour...I will report to you'll in the morning and tell you if its lost any or what.

hey beau, you can maybe check auto zone or a local parts house and see if they maybe have the UV light and glasses to rent, and shoot you a can of 134A with dye in it. then when you notice the A/c out again, use the UV light and glasses to look for the dye. and the guy above talking about ac oil attracting dirt, look at the front of your ac compressor, thats a popular spot to leak, it will be very oily if its leaking. also the crimps on the hoses where it goes from metal hose to rubber.
