jasonk:if you need help i'll help ya, i just replaced my heater core and a/c evaporator in my 2000 quad.
once the dash is out of the truck you have to evac the a/c and then unhook the two heater hoses from the driver side of the truck, hopefully you drained all the coolant out or you will have one big mess to clean, then you have to remove all the screws holding the heater box to the fire wall, this is done from inside of the engine compartment, ther are 5 on the fire wall engine side and one iside of the truck connected with a bracker wich you will see easily, the screws are as followed the 1st is on the driver side in plain view, the 2 is under a wire loom in the center of the fire wall, the 3 is right under it, kinda hard to see, the 4 is part of the a/c accumulator bracket, the 5 is really not connected to the heater box but if you do not take of the a/c accumulator bracket for the 5 you'll never get the box out and the 6 is inside the cab connected with a bracket, once you have the a/c discharged and both the heater lines off, the box should just pull out, given you disconnected the heater duct on the left side of the heater box, once the box is out there are screws all around the box and vaccum pump wires, you have to disconnect all of those wires and remove the blend door hold down to get the cover off of the box, if you bought a new heater core make sure that you use all the sticky foam tape that came with the new core, do not try and salvage the old foam as it is prolly soaked if you had a coolant leak, then dry everything out and make sure to check the a/c drain spout while your at it other wise you have to unplug it later, also the heater core and the a/c evaporator core will both just pull out from the box with no problems, i recommend replaceing the a/c evap core too as you don't really want to do it again, if the new core is thicker than the old one you have to break off a plastic tab on the heater box as it prevents the new thicker heater core from seating properly, once you get all this done. cleaned and reinstalled the whole thing is really alot easier to reinstall, as far as the a/c afterwards go to autozone or somewhere and get an a/c recharge kit, anyway i hope this helps and if you have any problems along the way i'll help you more if i can. also i forgot to mention that you will neeed to get an a/c line remover tool or you will not get the a/c lines off of the accumulator,also make sure you label all of the vacuum lines that you took off and where they came from other wise problems may arise, after i was finished with the whole job i found 3 screws that where left over, god only knows where they came from, and i hope nothing falls apart but it's been a couple of months for me now and so far no problems. good luck

Good point KJS about the special tool to remove the a/c lines.
I first picked up a sciscor type, but returned it becasue it was a pain to use and didn't work for me. I picked up a set of the platic ones from autozone and works like a charm! It is referred to as a "spring lock coupling tool" or "gas and a/c quick disconnect tool".
here's just a sample of what the ones i got look like.
http://www.chain-auto-tools.com/air_conditioner_tools/AMR575D.htm
The set ip got from autozone has 4 pieces.
those extra screws are probably from the glovebox/dash. first time I did it i had 3 extras, 2nd time I did it i had 1 :)

no clue where they go Dan, but it annoyes me that something might come off when i really need it, lol any way i read your other post about the a/c evac, i have not recharged mine yet after replacing my heater core but if it costs that much to evac and then recharge forget it, i'll just roll down the window lol.

I think $45 seems a little high but i may give in next week and pay it. I'm still calling trying to find somewhere. I may just end up buying an ac vac pump myself - I know i could get use out of it over a few years.

How much does it cost for a pump these days anyway? i found an a/c recharge kit at napa for 75 beans but even the guy there say's to evac first so i wanna buy it but i'm worried something will go wrong or maybe it will not work at all.

the ones I've priced on line are $150+. There is a small one you can get to use with an air compress for < $20.
The R134 is pretty cheap, $5 a small can (12 oz maybe, not sure exact size). Larget cans are $8. Some come with the pressure guage. You can also get 3 of the larger cans with guage with conversion kit to convert from r12 to r134 for $25-$30 (wal-mart).
What was in the kit for $75? That seems pretty expensive for just a recharge kit even for napa.

it came with a guage a couple of hoses 3 cans of r134a and 2 cans of the oil that goes into it to lubricate the system, i thought 75 beans was too much a well, but i might as well check wal-mart, i never really go to wal-mart my wife does, so maybe i'll get here to check it out, thanks Dan for the tip.

That kit I am referring to has oil mixed in with the r134 but you can buy it separately and the r134 with no oil.
parts stores carry pretty much the same thing - wal-mart may be a couple bucks cheaper with everything.
