Has anyone personally repaired/replaced the A/C evaporator core issue that I am led to believe is the cause of possible leaking and/or the A/C sounding like it's on a respirator? I'm going to attempt to replace it in the next few months myself. Currently I'm gathering all the information and knowledge I can before tackling the job. I just can't swallow giving the dealership almost $3k to make the repair considering I already paid them about $800 last summer to "fix" the issue. As it stands, I'll be replacing it with a TYC Evap Core. Any suggestions or tips on the necessary steps and tools side would be appreciated from anyone that has experience doing so.
