air conditioner problem
not sure where to post this. i have a 1998 ranger xlt 4.0 ohv 5 speed. runs great! when i put it on max a/c it blows out cool air but not as cool as it should be. i am pretty sure that it needs a little charge of freeon. gonna do that soon. the problem is that when i put it on regular a/c it blows out hot air. i mean hot air from the heater core. i replaced the little black panel that has the 3 knobs (to select the air mode, temperature, and fan speed). this didnt change anything.
all the vacuum lines look good- no cracks or leaks that i know of. the valve in the heater lines works as it should. the truck has 104k miles. every thing is original.
the previous owner smoked in it a lot. im guessing that one of the doors in the duct work in the dash is broken? or whatever moves it isnt working?
i am out of ideas so any help will be appreciated. thanks!
