It was a chip and her interior filter was damaged and i remove part of the dash to clean out a large plastic bag that got caught it her return vent. Chip free , filter 17.00 bucks! on your girlfriends a/c, i think she might have one of her lines that is leaking or a seal. A good place that could help is ICE COLD AIR, there are everywhere in the bay area, if not maybe i could look at it on the 2nd. Also where did she take it to and what did they said to repair it. (lines, seal, compressor or what?)
