So I thought I was a car guy til this experience that I’ve been having. I have a 2013 Hyundai Elantra for my daily driver. In the last month, I’ve replaced both the alternator, battery, and C/FAN relays. In which both the battery and alternator have been tested numerous times by me and parts stores. So I was dealing with my car constantly dying overnight despite the replacements. I begin to diagnose for parasitic draw and find that the compressor seems to be getting power when the car is off. I unplug the compressor the draw disappears. Also if I unplug the A/CON fuse in the engine fuse box the draw also disappears. The compressor clutch cannot be the issue because it tests with 4.3 ohms. There is no AC relay or compressor clutch relay in my car. There are C/FAN relays which both have been replaced and it seemed almost to have fixed the issue, but until a couple days later and what leads me to today the car is dead again. I’ve also disconnected the AC control panel in the car and that doesn’t reduce the draw. Wiring and ground to the compressor seems fine. With testing it again today I’m getting the same results with a draw of about .25. The wiring to the compressor does seem to be getting voltage when the car is off. I only tested it with what the basically dead battery was at (3.8V) and the wiring showed that it had 3.8V. Also all alternator fuses and such are fine, and the car doesn’t drain if I disconnect the negative terminal, or if I leave the compressor unplugged, or if I pull the fuse. Please help me through this humbling experience!
