The AC in my 1982 300 TDT has a fairly fast leak. If I get it filled it will leak out in a few days, which is too big a leak to seal with refrigerant additives. I have had about 3 charges leak out and they all had dye in them. I have a small UV light and the yellow goggles, and also I took it to a place with a "sniffer." We can't find any leaks, but to check the evaporator you have to do major surgery on the interior of the car.
After removing the front seats, console and dashboard (or as Mercedes calls it, the instrument panel) I have exposed the following - have a look at the picture at:
Has anyone ever replaced an evaporator in this type of system? Take a look at the pictures and you will see why I consider this a daunting task.
Thanks for any help. I called my AC guy and the labor charge is $1500 for them to do the job, so I have to figure this out somehow.
