    so i have a slow leak somewhere in my ac unit. put some dye in it and still cannot figure out where it is leaking from. if i charge it it blows very cold for about 24 hours then leaks down enough that it doesnt work anymore. any ideas?

    If it runs out in 24 hours, then you have a large leak. It shouldn't be to hard to find with dye, UV light, and glasses. When you get it blowing cold again, check for dye in the puddle underneath you truck. If there is dye, then you evaporator is leaking

    i forgot to mention that it doesnt totally leak out. just enough to make it not blow cold. the guy who filled it for me told me it was just a lil low. this is why im having such a hard time finding the leak.

    The condenser is in front of the radiater and the evaperator is behind the glove box. I used a spray bottle from home depot filled with soap and water and sprayed everything I could get to.

    ill have to try the spray bottle method. if it is the evap, is that comparible to changing a heater core? 2 lines one in one out, located in some kind of box. i do know it would have to be evacuated first.

    Yes it is comparable to a heater core, and you do need to drain your system. Then of course pull a vacuum when you put it all back together. I would reccomend a haynes manual it will show exactly how to take your dash apart. Its a good idea to call around to auto zone, oriellys and places like that first so you don't waste your gas. They won't always have your year model book on hand they may have to order it. Chilton will work but Haynes is much better.

    Sorry to dig up such an old thread, but i thought this might help someone in the future. Found another 97 in the junkyard and bought the whole box that contained the evap core and lines for 50 bucks, swapped em out and got it charged. Been blowin cold all summer now.
