Recently I started noticing my car was hard to start in the mornings and i thought it was a result of the cold weather we've been having. I would put my car on a trickle charger overnight and the ALH would start right up the next day.
Then I noticed that my AC push-button light would stay lit at times even when I had the blower set to the off position and the AC button not pressed in.
So I did an experiment:
I disconnected my battery overnight and hooked it up in the morning.
The car would start right up in the morning without assistance from a trickle charger or anything.
I noticed a "click" whenever I disconnected my battery.
Then, when I ruled out that it wasn't my battery. I watched my car as it was running. I found that although the A/C was off (vents sent to cabin/foot position, not defrost), the electric clutch on the A/C was staying engaged and dragging the engine. The only way I could make the A/C compressor disengage was by disconnecting the electrical connector on the A/C compressor.
Is anyone familiar enough with this system to help me figure out if a relay got stuck in the on position or whether something else went bad, thereby causing the A/C clutch to stay engaged even when the car wasn't running?
I don't know much about this, but do know that the A/C was the cause of my battery drain issue. Now that the electrical connector to the A/C compressor is disconnected, I have no issues.
