Thanks to Brutal on this forum for telling me that it can be fixed by a PC repair company (I actually own a network consulting firm). So with that knowledge I figured I would take a stab at it, what's the worst that could happen? Broken climate control module (just buy one on ebay, $150 or so if you can find one...)

Okay, so here are the pics and the steps. may come in handy if you don't have a jtis CD and don't know how to remove the trim because of it (lolrd knows I was worried).

You need to replace your DCCV first, because the board doesn't burn itself out. I noticed that when checking the DCCV when it is unhooked from coolant, it cycles when key is clicked to on position. Just look in the holes and you will see it move. Mine only moved on one side, so my climate control unit was bad.

Tools needed, solder, soldering iron, some small wire, a few torx bits for the center console, and some tiny torx for the climate control circuit board (or just cut a groove in them with a dremel tool like I did, and remove them with a flat-head screwdriver). 8mm socket (I think) to remove the climate control and radio unit from the dash.

First step, remove shifter trim by opening ash tray and pulling up like so.



Then open up center console and remove cup holder and fluid catch tray beneath it.



remove two torx screws that hold center console compartment in.



Lift up center console storage compartment and disconnect power outlet (yummmm.... KFC box in the background, less than a week old!)



Remove center console trim by first pulling up here



and then pulling back from this point on each side.



remove 4 bolts holding in climate control and radio



remove the crazy amout of wires going into all the sensors, buttons, radio, and climate control module. The bottoms ones just squeeze and pull they will come out



remove 4 torx screws that hold in climate control module



pry off air-bag distance sensor from back of climate control module



separate back cover from front on climate control module, by pusihing in on the two tabs



pull connector off of back circuit board



Remove four tiny torx screws to free up circuit board from back piece. (I had to cut a groove in them with a dremel and use a standard). Ignore the hole I cut out of it to get a better view..



Locate your bad trace (or 2 I guess, depending on how bad yours failed).



Follow trace from beginning to end, and solder a small wire from the pin going to the board, to the hole where the trace ends. For the pin going into the board, I just made a J with my wire, and hooked it around the pin and soldered it into place... For the other side, I just pushed the wire through, laid a glob of solder on it, then pulled it into the hole while applying heat (gently). I don't really know what I am doing with electronics repair, so there is probably a cleaner way to do it.



Test with Ohm meter, reassemble, and enjoy your air-conditioning (I know I am, its almost summer in southern california, I've been burning up!).
