some tips for anyone doing the Evap core removal and installing:---

-You don't have to remove the steering wheel. The steering column is held on to the dashboard frame and firewall by four 12-mm bolts. Remove them, and the paneling underneath the steering column, and you can drop the whole assembly and work over it. This way, the driver side airbag doesn't have to be removed either.

-The evaporator/blower box comes out as one piece. It's to the right of the heater core box. Once you get it fully unscrewed from the firewall, you'll notice it still can't be removed. That's because the evaporator is bolted through the firewall, and there are three bolts under the hood that hold the pipe in place. You'll have to remove these bolts, but THE SYSTEM WILL BE OPEN once you do. Be sure there is no pressure or vacuum in the line before you open it, and once you remove the evap/blower box, cap the opening in the firewall until you're ready to install the new assembly. After opening and sealing the system, you'll have to get a mechanic to evacuate it before you run the A/C. This is crucial - if you don't remove every little bit of moisture and dust, you could blow your compressor. Work quickly and keep your work area clean when you open the refrigerant line.

-Drape a blanket over the back of the crash panel when you're ready to pull it out of the car, so the sharp edges don't scratch your windshield or the paneling on your doors. It's a heavy piece, and it's a very tight squeeze to get it in and out of the car, so I'd recommend getting someone to help. Be careful with the dashboard so you don't bend it - you need to be sure all the mounting bolts line up when you put it back (one of mine won't go back where it belongs).

-LABEL YOUR WIRE HARNESSES. I did this by attaching a strip of duct tape to each one and writing on the tape with a sharpie. If you're like me and you know absolutely nothing about wiring, or cars in general, then this will be essential for putting everything back together. Leave notes for yourself, so you know how to plug it all back in. I also kept track of where all the screws and bolts went - for each component of the dashboard, I would remove the screws and bolts and put them in an envelope with the correct label.
