So a while back I noticed my battery was having issues when the car would sit for a while. It seemed fine after long drives so I figured the alternator was good. I replaced the battery and the issue persisted.

Long story short, I used a current testers and found that there was a draw on the battery with the ignition off. I pulled fuses until I found that the circuit for the interior lights was the culprit. I have since left that fuse out without any more problems. Apparently that circuit also controls the keyless entry system.

Electrical draws can obviously be a huge pain to diagnose, so I was wondering if anyone had a similar experience and found the cause.

Thanks!

 

the HFL is a known cause of parasitic draw.

check the Hands Free Link Module.

 

I'll check it out. Thanks!

 

Easiest way is to put your hand on it in the morning with the car off overnight. It shoulf be warm.
