After 26 years, it is time.
Well I got in the C126 and the Texas heat was coming but the airflow inside the car was hot. From perfect the day before to nada! Removed and replaced Klima relay, no change. Hooked up a can and I was EMPTY, no refrigerant. 1 can in and compressor came on, 1/2 can and aux fan kicked in. Cold air back from auto-part store. Few hours later, fire up car and cool but not cold, I backup and breath the band-aid smell of 134a. Stop the car midway down the drive and there it is, worst nightmare! Dinner plate size gob of green fluid smelling like a case of bandaids. Go back and look at transmission and its dripping green condensate. So I either have O ring failure at the evaporator or failure in the core itself, not possible to get refrigerant out the drains, those items are sealed deep in the bowels of the airbox.
Dash removal, and replacement of Orings, expansion valve and new evaporator. While I am in there, replacing vacuum pods that I did not replace in 2012.
