Hi everyone! I've got a 2007 G6 and I love it! I do have a question. I used my ac for the first time yesterday. I switched it to recirculate the air and this morning, when I turned it on, it's making a "clicking" noise. Sounds like it's coming from the glove box. When I switch it back from outside air to recirculate it stops. Does this mean I need to replace the blower/mixer? Thanks!!
