So...I was told that my evaporator has a big hole in it. My AC stopped working about a month ago (I live in Houston, so I will need it soon). Noone has actually looked at the evaporator to confirm that there is a hole in it. When I first purchased the car (6 months ago). the AC made a hissing sound for a while and then stopped working. I had the freon refilled, and the hissing continued and the AC eventually (weeks) stopped working again. I had my cooling fan replaced because the low-speed resistor was not working. I figured that the AC was overheating and hence ejecting the freon. I had the freon refilled, and the AC worked great for 4 months or so. Then the hissing came back, and the AC died. That's when the evaporator was diagnosed with a hole.
Is there release valve that might be stuck open that would be fooling my mechanic into thinking that the evaporator is leaky? I trust my mechanic, but also know that he doesn't have much experience with Saabs. Is there anything else that could be causing this problem?
If I do need to have the evaporator replaced, I decided I might as well replace everything but the compressor (e.g. the anti-frost switch, the drier, switch/es on the drier, evaporator, etc...) Should I also replace all of the AC piping? Any other suggestions? That wasn't in my plan, but if it is necessary. This is a huge task, and pretty expensive.
Lastly, I think the drier has switches on it. Because I am now in Houston, should I install two switches (for use in warm climates I think) or just remain with the one switch? Thanks.
