Car is an 04, a couple of weeks ago the battery went dead so i jumped it, but it died again a few days later, so I just replaced the battery. Old battery was an unknown, was in the car when we got it and I didn't bother trying to decode its age, I just replaced it. A week of so later it is dead again, so I know I have a bad battery or a draw. Put another known good battery from another car in and within 3 days it is dead, so I know I have a draw. Up until this point everything was working fine, I just had to find my draw.

Started off with the good old VOM and some fuse pulling but I couldn't find one that effected the draw so I removed the alternator and taped up the cable. Charged the battery and let it sit 3 days, no luck, battery dead. So I put another battery in and tried the fuse puling again starting with 9 & 35 that seem to show up in every thread. No luck there, but when I got to #23 "soundbooster" the draw dropped into the normal range. I put that fuse back in and pulled the radio fuse to see if the radio, an aftermarket Kenwood, was giving the amp a signal, but the draw remained the same. So now I've located my draw and I go searching for this issue but don't find anything about a constant draw with the amp, has anyone had this problem before? That fix is easy, I just left teh fuse out and teh battery has stayed up for 10 days now.

So now I notice that my interior light isn't working, my initial thought is I had it turned off, so I wasn't concerned. Next I realize that the power locks are not working.

When I push the button on the fob the lights flash and I can hear the relay clicking so it appears that that much of the system is working, but no sound from the back. Went back to the fusebox to make sure everything was good and it is. Did some reading and found out about the water problem in the right rear so I pulled it apart, but it is dry as a bone. Probing around with my VOM I find 12V at 2 of the larger wires but I don't have a clue from there. I took the pump apart and briefly applied power directly to the pump motor and it ran. So now I am at a loss as to what is next. I haven't been able to find a schematic of the system that tells me what wire triggers the pump and clearly this module runs lots more stuff. Anybody out there have an ideas or suggestions?

I have to think the amp and the locking pump module are two different issues that just happened around the same time.

Any thoughts? Thanks in advance for any suggestions!
