I have an AC leak that seems to cause loss of AC pressure in a single day. I noticed a lot of green UV dye emptying out onto the driveway along with the condensate drain water from beneath the firewall area, slightly on the driver's side. I also notice a smell inside the cabin, particularly when the AC is off and just blowing air. Curious, is there a rear evap core drain location that's separate from the front drain, or do they drain together? I just want to make sure it's the front evap core before I rip the dash apart. The only location that I've noticed dye using a UV light is beneath the center/driver's side firewall location. (see photos). Thanks!

Oh, this is an 09 Acadia, BTW.
Unfortunately you have to replace your front evap core. Just did mine, not too bad.
