Hi,
My 2012 Tahoe a/c was working fine (it was too cold and I had to raise the temp. That afternoon it would not get cold) and just started running hot, both front and back. The only cold line under the hood is the line going into the firewall to the right of the drier (it gets very cold, but the drier is not cold). I changed the blend door and re-calibrated it with no help. The compressor seems to cycle on and off every 10-20 seconds or so. Re circulation works as does the defrost, floor, and panel switching. Any help would be appreciated.
Thanks,
Wayne
