AC doesn't work. 99-C230
I have a 99 c230. The AC didn't work when I got it.
My mechanic emptied the system and filled it with freon. It worked for a few days and then my dad pressed the circulation button and pressed the EC button and then it stopped working.
My mechanic then emptied it again, there was a ton of pressure when he opened it. He filled it again with dye, it worked again for a few days and then stopped working again. This time, without pressing any buttons.
Any ideas?
He's telling me, let's empty it and do it again. I already paid $160.00 to him, $80,00 each time to refill the AC unit.
