Q: 1.69 amp parasitic draw, previous owner had hitch. Everything stock

asked by on

My battery keeps draining I figured out the car was drawing 1700 mA when off- all doors closed lights off nothing plugged in. I can't seem to find any wire near the tai lights/engine/under loose or corroded. Any suggestions? Ideas? I've been trouble shooting for weeks now

My car has 140000 miles.
My car has an automatic transmission.

The best way to find the draw is to pull fuses out one at a time. This isolates which circuit needs to be diagnosed. You may have a module (computer) that is not going to sleep. I found a technical service bulletin for just that. The sunroof module may need reprogramming. The dealer is the only one that can do this. The TSB is #08-015-07. However, if you are out of warranty, they will most likely charge you for this.
