Battery Drain
Ok guys, I have read through the various threads in the forum, so please don't blast me for asking for help. I have a 2002 that I bought just a few months ago and the previous owner installed an after market stereo, with the iPod charger adapter. So after each use, I disconnect the ipod and things seemed fine until I parked it for three days and the battery was completely dead. I have replaced the battery previously.
I am also having the turn signal intermittent disfunction as well as only the center brake light working on occassion.
It is getting really frustrating. I am asking for help. My frustration level is rising daily and I am almost to the point of selling it, I have wanted one my whole life....don't let me do it. I can fix things that are broken but the electrical stuff is foreign to me.
Thanks in advance...

Some of the I pod adaptor harnesses were wired incorrectly and caused a constant drain on the battery. The stereo section covers this.
If you measure the actual battery current draw, with an amp meter, it should be 0.025 - 0.020 amps (25 milliamps). If its higher, you need to find what is not turning off and not letting the BCM go into the SLEEP Mode. It takes the BCM 8-15 min to go to sleep so when yoiu first connect the meter in the circuit, you will see a HIGH reading 7-8 amps and then it will work down to it finial low sleep current draw.
Have you seen the current draw info in my stickey post:
