I just used his excellent instructions to remove the dashboard and replace the missing foam in the air box.
pull apart the air box to replace the foam (yeah, the next picture is upside down)
Then re-install the heater box (that's it just below the horizontal silver bar on the passenger side)
and re install the dash
This project is not for the faint of heart. Without Meir's DIY instructions it would be a real bear with lots of "hidden" fasteners, and lots of fasteners to find period.
The AC system also has to be opened and the seals and R134a replaced. After re-assembling the AC the system is pulled to vacuum. Since the system needs 850 grams of 134a, I decided that to use a kitchen scale to weigh the R134a going into the system. It worked great. I didn't even run the car.
I put in one can using a hair dryer to heat the can, then weighed the empty can. The system takes about 2 1/2 cans. Weighing the second full can showed there were about 6 grams more 134a in the can than the weight on the label.
Doing a little math showed how much the last can should weigh to have 850 grams so I had it on the scale as it was charging the system to watch the weight decline. Voila! 850 grams more or less exactly into the car.
After putting that in the car I went into the house and realized I'd put exactly 100 grams too much in the system. AAACK!
This morning I hooked everything back up, but put the R134a can in an ice bath on the scale. It's cool in a science geeky sort of way to watch the R134a go back into the can. After condensing 100 grams back into the can, I cranked up the engine and for the first time since I''ve owned the car enjoyed frigid AC and blistering heat.
Thanks again Meir!!!
