I have a pretty big leak in my evaporator. I can hear a hissing sound when it's pumped with freons.
So I'm going to replace it, along with the expansion valve and the receiver drier.
It's quite a drag to get to the evaporator since complete dash disassembly is required.
Is there anything else likely to fail that I should replace while I'm in there?
Sorry guys, I forgot to add the model. It's a
2007 Toyota Camry `ACV40 (JDM Model).
I figured out it's a leak because it keep losing pressure along with the hissing noise. Also I've never heard that kind of hissing noise before, it was like air escaping from a pressurized container through a small hole. The system has no colling whatsoever at the moment.
