Air conditioner evaporator leaked the refrigerant out in about one day. I installed a new evaporator, and replaced the heater core while I was in there. That was almost a year ago and it is still working great.

It started with a leek of the heater core flooding the interior and letting the front window swet al the time, I disconected the heating, it is not a problem here and this problem was solved for now. But shortly after that A/C failed and a check of a specialist diagnosed a leak in the evaporator. A/C is needed here, so the dashboard has to go off, thats the oportunity to repair both.
