Q: AC compressor seized

asked by on

Hello. You have several problems to sort out. The first thing to do is an OBD II scan for fault codes, although these may not be related to the AC problem. The AC problem could involve several potential issues including the dash control unit, sensors, the high pressure valve could be stuck or not working correctly, or there could be underdash ducting and control mechanism failures. I recommend hiring an experienced mechanic to start with a detailed inspection of your entire AC system, and address the other issues.
