For the past few weeks, I've noticed a problem with my car. While I don't think this is related, let me preface this by saying that 2 months ago, I got all 4 engine coils replaced. The battery is 6 months old and the proper battery for the car, and I've double checked the cables, they're tightened properly. The car was used when I got it, but there's no after market radio or anything of that nature that would seem like an obvious cause. The first few times this problem presented itself, it seemed minor. I was driving and the radio more or less reset itself. Was off for 2-3 seconds and came back on, I noticed no other problems, so I assumed it was a loose wire/fuse. The next step was that the air conditioner went along with the radio. Again, 2-3 seconds, no interference from me, and it came back on its own. The next time was a little more severe. Everything above, plus all the lights on the dash came on as if it had stalled, but it did not stall, the car does keep running while this happens. Again, 2-3 seconds, and things were back to normal. I kept driving it, and it happened again about 3 minutes later, but was fine after that. I took it to Advanced Auto for a systems test, and he did find that something was draining the battery (what should be .5 amps or so was 26). I think the problem MAY be related to the air conditioning. The times it's happened so far, I've had the AC above the lowest setting. If I kept it on the lowest setting, it seemed just fine. Today, the problem happened four times on my way home, three within maybe five minutes of each other. The only thing I'd done was switch my AC to defrost, but as it was raining, I had my headlights and wipers on. Also, this does seem to act up on the hottest days (hence the need for more air, today was a record breaker heat-wise), so someone suggested that it may be more temperature related than AC related? Again, these are only speculations, but they're the only patterns I've noticed for sure. I'm fairly certain I have a short, but I thought it might be my best bet to ask here first, and if any of you could give me an idea of where to look before I take it in for a complete electrical servicing (money I do NOT have thanks to the $700 coil problem), I would really appreciate it!
