How do you replace an evaporator core

The Evap is located inside the vehicle under (in) the dash interior. To obtain access; you have to virtually remove the ENTIRE front end of the car - stripping it down to just the firewall. Yes, you have to remove the steering wheel, speakers, electronic components; dash displays, heating/vent controls, etc. etc. etc.
FINALLY after dealing with a TON of hidden fasteners; being upside down and disconnecting various bolts, screws, and nefarious wiring connectors - you will have all of the front end of the car out - a lot of times this will also require removing a type of long pipe which some wires might be running in (partially); whose main purpose is keeping the side of the car from collapsing during an accident; and also providing partial support for the 'safety pad' or main portion of the dash.
This is a BIG job; and totally requires a FACTORY manual; or a subscription to 'alldata'. A good condition Factory manual could be obtained possibly from a dealer or from 'books4cars.com'
The Evap is also usually located inside of a large plastic housing which is also going to be holding the heater core; and some other components; and you have to be careful disassembling the 'box' to get to the evap.
A 2007 generally doesn't have any problems with the Evap at this point. Why are you wanting to replace it?? Are you sure this is the problem?
Technically, you also are supposed to recover any refrigerant; rather than just letting this vent into the atmosphere. If you don't know what you are doing; disconnecting a line incorrectly can give you severe frost bite and send you to the hospital.
If you are comfortable with all of the above - since NONE of it is an exaggeration - then really - get yourself a FACTORY issued manual. Hanes or Chiltons will NOT cut it for this info.
You will still need to be VERY careful with a bunch of plastic components; and you will probably break a few trim pieces - but they should still be available to purchase.
TAKE PHOTOS. HUNDREDS of PHOTOS.
After all is completed; you will still need to 'evacuate' the system (bring it to a vacuum via a pump); otherwise it will not work correctly because of the moisture which is in the system from the air. The moisture will freeze in various places; and cause severe problems (like in the Expansion Valve). You should also replace the receiver/dryer (important to do that - no joke.)
In other words, this is not a job for the faint of heart; or for those who do not know what they are doing. I have done them on Camry's - but I am a licensed Aircraft Mechanic. I don't enjoy all the work and time requirement to get it done correctly; without damaging a hundred easily damaged parts.
If you own a Manifold Gage set for R134a refrigerant; and a vacuum pump; and know what you are doing - or are willing to go to the LIBRARY and do some serious reading first on how this stuff works; and you have the TIME - then go for it after you have obtained a FACTORY manual; and you still take HUNDREDS of photos. (Believe me - you WILL need them!)
OTHERWISE - take it to the dealer (who theoretically) knows all about the numerous hidden fasteners; and won't be breaking a ton of them...
