The TCA is loacated in the evaporator case, partial disassembly of the case is needed but removal of the dash is not needed to do the job as mentioned above.
You'll need to remove the glove box, 6 screws.
You'll see the TCA connector clipped on the front of the case with a wire leading into the case, the connector is white.
remove the small silver colored screws that hold the case halfs together and then remove the 2 gold colored ones that hold the case to the firewall.
Here comes the tricky part, pop the case open and gingerly slip your hand in there and temove the probe that is pushed into the evaporator coil, try not to overstress the case as it could crack. Small hands are a must for this.Insert the new probe in the same general area.
Then reassemble all and thats it.
