after removing the heater control cable the dash came loose with a upward and outward tug. the heater/ac box came out with a little difficulty still but I was glad to finally get to at the problem area! once I separated the heater box I found that the AC core was the one that was clogged with all the dirt and dust. I would say that it was 60% or more clogged. and the heater core was OK. I took the AC core and sprayed it with oven cleaner then rinsed it and repeated this process twice. it cleaned up really good! I also found that my vent door hinges where dust/dirt filled also this might have been alot of the cause of the air flow problems that I was experiencing. I used some white grease to lubricate all the hinges then put the heater/AC box back together. putting the box back in behind the dash was as hard as removing it but after wiggling it around it fell into place! I hooked up the heater hoses and vacum lines and blower motor wires and did a test to see if all was working right and to my surprise it was just like brand new! I think the hardest part of removing the heater core/ac box was the fact that you had to deal with so much other non related issues like draining the ac lines, removing the steering wheel. remove all of the dash parts and side panels, center console, seats so you can have room to work, vacum lines etc....If you are going to attempt this job I would recommend using some of these tools. duct tape for holding the insulating/vacum lines in place while you install the heater box, silicone for sealing the places where you cut the the insulation to break open the box. a shorty Phillips screwdriver, steering wheel puller, ac line disconnect tools, this has been a real challenge and I wonder what a dealership would charge to do this job? I wonder how much money I saved by doing this job myself???
