I'm a new MBWorlder w/a CLK 320. I hope it's not rude to ask right off the bat, but the temp here in West Tx is a high of 105 today, and my a/c is blowing hot air. MB cannot get me in to check it out until next week, annnnnd I am 45 miles from the closet MB dealer/mechanics. Please help! I did the code checking and here's the results. 1 - 75, 2 - 70, 3 - 78, 4 - 78, 5 - 75, 6 - 17, 7 - 0, 8 - 76. I would greatly appreciate any suggestions that would be helpful. P
