I have had this problem for years and decided to try and get answers or fix this A/C problem. The air comes out cool for around fifteen minutes or so and then stops blowing cold air. One diagnosis was a relay or thermostat in the condensor overheating causing cool air to stop. I just took it to the dealer and they say I need a new compressor and receiver/dryer
$900.00 They said the compressor is rattling away. I just did an ac code check and got-188 two different times. This number isn't on the check list. Anyone have any ideas based on this. The car just went over 90,000 miles. Thanks.
