Hello, I own a 2006 Equinox LT. For several months now the A/C keeps freezing up. I will have the A/C and fan on then about 15 min into the drive the air flow almost comes to a stop. I will turn the A/C off and leave the fan on, eventually the air flow will come back up to full force. It is almost like you can smell ice melting and sometime i have seen ice come from the vents. I have checked it for leaks and changed the in cabin filter. Please if anyone can help with this that would be great.
