Beefy NOrm Posted July 18, 2022 Share Posted July 18, 2022 Multiple sensors have gone bad and have been replaced. This has become a continuous thing over 6 months. Local Mack dealer says it can’t be a bad VECU, but a non Mack shop says it can’t be anything but the VECU. Recent issue is that it has burned out two A/C compressors. It is somehow ruining clutch’s because no power going to clutch. Also no A/C in sleeper but cold or very cold fluctuations up front. Mack North America has not replied to pleas for help. What is going ? Help needed. Quote Link to comment Share on other sites More sharing options...

Mackpro Posted July 18, 2022 Share Posted July 18, 2022 He have been getting bad AC compressors right out of the box for our Anthems and CXU’s . We started Ohms testing the clutch before we put one on now. And these are Mack ones for the dealership. The HVAC control panel and the door panel switches also seem to have a high failure rate . The newest door control panel part numbers seem to do better. Quote Link to comment Share on other sites More sharing options...
