The heater core on your Park Avenue is under the dash on the passenger side. There are some covers that you will need to remove to access the heater core. I would invest in a service manual for the car these things can be hectic to get out. you can pickup A manual at your local parts store for around 20$ well worth the $
ARE YOU SURE THIS IS THE PROBLEM. Is the heater core leaking if so you would smell antifreeze inside your car the windows would fog on the inside and you would probably have a puddle of antifreeze on the passenger floor board. If its not leaking have the system flushed out
it could be clogged up
My first guess is that the thermostat is sticking open not allowing the coolant to get warm enough to produce much heat id have this checked first cheaper repair and easier to do, also check the antifreeze level, low level could cause this to. hope this helps
1st make sure it's the heater core. Usually it's the passenger side that is wet. To confirm it's the heater core, 1. do you smell antifreeze? It has a sweet smell, and should be easy to notice it if leaking. 2. Do have a problem with the windows fogging up, and turning on the defroster doesn't help or makes it worse? If the core is leaking, the moisture from the leak will fog up the windows, and the defrost mode struggles to clear the glass, as moisture is blown up the vents onto the glass. If 1 and 2 don't exist, the water on the drivers side is most likely a leak from rain along the door gasket, or windshield, or firewall.
You have an antifreeze leak. Probably in the heater core (a small radiator inside of the dashboard that heats the air as it passes through). When the engine is running do you see any steam around the engine? Or smell the sweet antifreeze smell around the engine? If not then it is probably the heater core instead of a hose or somewhere on the engine. Does this truck have the option to switch the heater to recirculate he air inside the cab instead of drawing in outside air? If it does then you can set it to recirculate the air inside and if it still has the smell then its definitely the heater core. Often with a leaking heater core the passenger side floor and firewall area will get wet, but not always.
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.
