I have posted on this many times before and thanks to all that responded. I have an air conditioner problem. The passenger side will not stay at a constant temperature. The truck is a 2004 SLT with out dual zone controls. I have had nine attempts in one year to fix it. I have even had a meeting with the district service manager on the last attempt. The last repair was replacing the evaporator and fin temp sensor. Other repairs have been done but all that was done was rechecking and testing. I got a call from my dealer on Friday 7-29 and thay said they dont have anything else they can do to fix it. I have had blend doors replaced twice, freon checked and charged to the correct level and the final attempt as stated above. I have called other dealers but they all tell me the same thing. The diesel trucks with the regular controls all have this same problem but the dual zone controls do not. I have filed arbitration papers yesterday. I also went on the consumer affiars web sight here in Georgia and filed under the lemon law. I dont want to replace the truck, I just want the issue fixed. Can anyone shed some new light on this subject? Thanks in advance--- Chuck
