If you're planning on removing and replacing an a/c component you're going to need an a/c machine to recover the refrigerant with and to check your system for leaks once the component has been replaced. you're better of just taking it to a shop

the entire dash, door to door top to bottem has to be removed to be able to take out hvac housing so you can take apart to get at the core [recomend do heater core at same time] the dash comes out as an entire unit guages and all. bolts on ends under plastic covers,on top near winshield under vent trim.,bolts on floor in center below radio and a/c controlls,steering column has to come out. multiple wire connectors etc. its an all day job for a pro so its going to take awhile but its pretty straight forward
No just the Radiator and take it to the Rad people for perssure testing first before doing any work on it as if it shows more leaks under pressure than the one you have Dont get it fixed as it will be out again in 3 weeks get it recored and fit a new thermostat the same time..
The heater core is a bit tricky and time-consuming, but you can do it if you take your time.
Remove the following: 1. Negative battery cable from the battery (just to be safe) 2. Drain the cooling system. There is a valve at the bottom of the radiator for this purpose. 3. Raise the front of the vehicle. 4. Disconnect the A/C drain tube (it is just a small tube that allows condensation from the evaporator to drain outside of the car) 5. Remove the heater hoses from the heater core. These are only accessible from underneath the car and run through the firewall. 6. Center console 7. The kick panels/under-dashboard sound insulators 8. the filler around the steering column. This just pulls off if I remember correctly 9. floor air outlet duct (also just pulls off if I remember correctly) 10. heater core cover - this is held on with several screws - maybe even a dozen or so. It is much easier to get access if you pull the carpet out of the way first. 11. remove the heater core mounting clips and the heater core.
Installation is the opposite of removal.
Be prepared to have a sore back/ribs after doing this. You'll definitely want a flashlight and maybe a mirror to help you see under the dash board.
Yes, there is not an access hole that allows any other method. Start by disconnecting heater hoses, then remove dashboard ***'y. Not too bad on Jeeps. Then you may or may not have to remove the whole HVAC box depending on where the lid for the heater core cavity sits. Usually this whole box must come out to get heater tubes thru the firewall. Then you can take the cover plate off, unbolt the tiny screws that hold down the arms, and remove the offending core. Good luck, takes me a day or less, and I've done it for years. Worth the 400-600 plus that shops charge for this if you are not into meticulous work, tiny screws, and lots of crawling around inside a Jeep. Don't worry, you're not alone in this. Only a handful of today's cars can be re-cored without removing the dash, or at least setting it back on the seat (on a blanket) to gain access to the HVAC box. Hope this helps you make your decision. TT
Hello. My name is Chuck and I owned a radiator and air conditioning repair shop for 20 years. The answer to your question is the whole dash board assembly. You need to remove everything to gain access to the evap core. I'm sorry to be the bearer of bad news .At my shop everybody wanted their a/c fixed but nobody wanted to pay the price and I can't blame them. I charged 800 to 900 bucks complete for this job and the chrysler dealer charged about 1200 plus for the same work. Good luck.
